Guys and on me on the go, when I was driving with kondeem in the salon, the sharp smell of the type of wiring and condo is finished working. What is thinking?

Hello. And at the moment I have the same thing, the smell of something burnt and after found that the climate does not see. You have something bad luck. Temperature on Street 7. It was necessary to turn on.

Confressor Konduyuk Daughter. Notpor did not clean the radiator, he clogged, ultimately overheating the system is excessive pressure and here's the result! Now, under the replacement, the radiator and compressor. Although there may be a radiator!

Have a good time day. He will not be flown with you, the temperature of the condushka does not affect the temperature.

but on the sink, when the car was fingering, I heard how the condo and the air is a cool bleach.

The air conditioner compressor coupling is not included. There is no mass on the air conditioner compressor

Not The compressor coupling is driving air conditioner. On compressor air conditioner No mass. VW Golf 4, Passat, Polo, Bora.

VW Polo Sedan ( air conditioning Bad cooling) hot air flow damper!

Try to turn on once again. The handle is all on the glass (up) Press the A / S.Oll button will determine the characteristic click. Glue the compressor, the pulley should be spinning, the engine speed will slightly fall, the evaporator fan will turn on. (depending on temperature) if you have all the rules. There will be a question on cold, write

Hi, tell me the same story The indicator is fastened but not turn on and there is no characteristic click, where to climb what to watch, maybe there is a relay?

Infa was confirmed, I checked on the car. Condes turn on I. works))

Check the pressure of freon in contours. More details describe a malfunction.

i think on lethah I figure out 100% works he or not)

I had it in the spring, but the degree was 10 somewhere, rain, slush. In the morning I started everything worked, I drove to the mother-in-law, went to her for half an hour, then came out, started, drove and feel straight stiffishly terribly and the windows sweat. I come on to poke the Condeye button (I have a sleeper-control), but nothing happened! In the evening, it climbed into the Internet, and a hundred there just did not read, I decided to also sign up for the service! BUT! In the morning, the machine was pleasantly surprised, condo works🙂

well, right now, it shows, tomorrow if I also go to the garage and check there.

below 4 will not turn on.

Where does this information come from?

on the street how many degrees? After 0 degrees, it will not turn on.

The new Volkswagen Polo is very popular with the vehicle in the world, including on the terrain of Russia. Our client remains that there is that the famous German manufacturer managed to cooperate several important features in this machine: usually the highest German quality and the price that makes this car very easier ...

Read 8 min.

A quarter of a century ago, on Russian roads with closed windows, only wealthy people traveled on foreign cars. They could afford to include air conditioning and enjoy a pleasant cool fan during a sultry summer sun. The currently modern car is difficult to imagine without any primitive cooling system of the salon. The air conditioner for the surcharge even our frets. What can we talk about multi-zone climate control systems of luxury SUVs, in which the hot summer can be arranged without any problems, and to give a real winter to another.

The Volkswagen Polo sedan, as sharing a comfortable Europeans, will be guaranteed to save from the heat of its owner. True, adventures with air conditioning start only from Trendline. In the "base" there is only a notorious stove.

Independent dismantling of the compressor and its typical malfunctions

The chapter of the entire complex is a traditional compressor. His main task is to force the refrigerant to circulate on the system. The device is located on the cylinder block. When you start the car, the polycliner belt leads the compressor, the shaft of which is on the bearings on the top cover of the case. With the help of a clamping disc clutch, the power factor comes from the constantly spinning pulley to the compressor shaft. If everything is normal with air conditioning, then when you turn on the function, it is possible to click. This means that the clutch disc came into contact with the pulley, which handed the pulse to the compressor rotor.

Main compressor malfunctions:

1. If the coupling began to creak or the vibrations appeared, then in most cases the symptoms mean a breakdown of the bearing under the disk. In the most launched situations, you will have to repair and replace the coupling itself or its components.
2. If the click you did not hear, then options are possible: the refrigerant "escaped" from the system, the pressure sensor broke down, the electrical circuit, or the electronic engine unit, or the electronic block of the engine decided to block the compressor inclusion (for example, due to overheating).
3. If the coupling works on "Hurray", but there are unpleasant grinding sounds or vibrations in the system, here, alas, the compressor itself is to blame. Repair is excluded - the aggregate will have to find a worthy replacement.
4. The saddest scenario: everything is in order with the coupling, the click operations and there are no vibrations, but the cold air does not enter through deflectors in the cabin. It only remains to apply for specialized help to experts to determine the cause of the breakdown.

Dismantling compressor with your own hands:

The honorable place in the air conditioning system is occupied by a multi-threaded condenser, or in a common radiator. It is installed on the brackets attached to the main "battery" of the cooling system. The radiator condensates the refrigerant pairs, which has passed the stage of preparation in the compressor, and gets rid of the heat generated by the reaction.

Replacing radiator air conditioner

The cells of the radiator need constant cleaning, which is recommended to be carried out at least once a year. It is necessary to rinse carefully, in order not to damage the thin ribs of the device. However, withstanding all tests with water, the radiator will not be able to oppose the inevitable corrosion, which will begin to destroy the metal for the third year of the polo sedan. About repair can not go speech: Zalagov the tiny holes in the housing, after a while you will have to face new holes. And the welding now is not cheap. In addition, some of the finance will take on the removal / installation of the radiator and its refueling. It is easier to purchase a fresh unit: analogues - even debt.

Replacing the radiator of the air conditioner:

On the polo sedan with the climate control system, you can find the air temperature sensor in the cabin. So that he gives faithful testimony on the scoreboard, inside the compulsory blowing complex is installed. The sensor holes should be protected from dirt from entering and in no case to process the vacuum cleaner, since the latter is able to violate the correct operation of the device.

But the data of the external temperature sensor should not be relying. Located behind the lining of the radiator, the sensor easily changes its testimony due to the heating of the motor and long downtime in traffic jams.

The useful function performs the solar illumination sensor. It is located on the "tidy" near the windshield. The sensor studies the degree of heating of the cabin and effectively redirects the streams of fresh air on the head and foot of the driver.

Finally, the main character, the giving comfort and freshness in the salon of the polo sedan, is the refrigerant. Freon carries the HFC134A index (R134A). The volume of refueling for each car is individual. For Kaluzhanin, the norm is 500 grams. Inside also poured a small amount of special oil. It is important to observe the brand of refrigerant and oil and do not interfere with other liquids.

Freon removal from the system:

1. Turn the protective cap from the service valve.
2. Carefully pressed the thin screwdriver to the spool and slowly whip the substance.

In conclusion, perhaps the most banal and widespread cause of the air conditioner failure is a blown fuse. This happens even on new polo sedans. There is nothing terrible in a similar "accident": it is enough to climb into the fuse block and replace the spoiled element to a new one. Coordinates: top row, third right, green. A couple of minutes and - ready: Fighting heat continues!

The heating, air conditioning and ventilation system is a single complex that provides the most comfortable conditions in the car's cabin, regardless of the weather conditions and motion mode. The system includes a heater (increases the air temperature at any modes of operation of the system), air conditioning (reduces the temperature and humidity of the air), the air pressure (fan) and filter air ducts (provide air exchange in the cabin, clean the air from dust), as well as the control unit ( Manages all the elements of the system to obtain specified comfort parameters).

A liquid type salon heater is installed on the car.
The heater radiator is combined with the engine cooling system with two hoses passing in the engine compartment.

The radiator is placed in a plastic climatic block cover, mounted under the central part of the instrument panel. Basic heater nodes:

Heat exchanger (radiator) 6 heater designed to heat the air coolant entering the air to the air salon;

fan (air supercharger) 11;

For clarity, it is shown when the blows of the air of the inflow and the air intake are shown.

Electric motor 12 fan with excitation from permanent magnets, providing an adjustable outdoor air supply to the heater and air conditioning valves. To obtain different values \u200b\u200bof the fan speed in the power supply circuit, an additional resistor unit is installed;

The valve 2 of the air distribution coming from the heater through the air ducts into the salon or to blow the windshield.

Features of the device of the air conditioning system

On Volkswagen Polo cars, the sedan has a compressor air conditioning system. The heater nodes and the air conditioner heat exchanger heat exchanger are connounted in one block. The air conditioning system controls are located on the panel, common with the heater controls.

The compressor is installed on the engine cylinder block and is driven by a polyclinite belt. The compressor provides the circulation of refrigerant in the system. The compressor shaft is installed in the aluminum front cover of the housing on the bearings and is sealed from the drive side of the drive with the gland. The compressor drive pulley is mounted on a two-row ball bearing and when the engine running is constantly rotating. The torque is transmitted from pulley to the compressor shaft through the slave disk.

Circuit diagram of refrigerant movement in air conditioning system: 1 - combined pressure sensor; 2 - a plot of high pressure pipeline; 3 - Receiver-desiccant; 4 - High pressure line service valve; 5 - condenser (air conditioner radiator); b - condenser fan and cooling system radiator; 7 - air conditioner compressor; 8 - Low Pressure Pipeline section; 9 - service valve lines of low pressure; 10 - heater fan; And - evaporator; 12 - thermostatic valve

If the system is properly, while the air conditioner is turned on, the clutch is a clamping clutch disc under the action of an electromagnet comes into engagement with the pulley of the drive, and the compressor rotor begins to rotate.

But during the operation of the air conditioner, the following compressor faults may occur.

1. If, when the air conditioner is turned off, there is extraneous sounds during rotation, the smell of Gary is heated or appears, it probably began to collapse its bearing. In this case, it is necessary to replace the bearing. In some launched cases, it may be necessary to replace the compressor coupling assembly or components of its parts.

2. If after switching on the air conditioner, it is not audible, then the following problems are possible:

Refrigerant leakage occurred, and the control system blocks the inclusion of the compressor;

The pressure sensor in the system has failed;

Malfunctions in electrical circuits of the control system;

The winding of the coil of the coupling electromagnet burned;

The engine control unit for any reason (high engine cooling fluid, high engine speed) blocked the enable compressor.

3. If the coupling rotates easily and freely, but when you turn on the air conditioner, extraneous noises are clearly audible or even stalls the engine, then most likely sworn

Compressor. The inner pumping part of the compressor is not subject to repair. In this case, the compressor will have to be replaced.

4. And the last, the most unpleasant option. Click is distributed, the coupling easily rotates the compressor shaft, and the cooling of the air in the cabin does not occur. In this case, the compressor works in a frightened, nothing pumping. Only an experienced specialist in the presence of special control and diagnostic equipment can determine this malfunction.

You can most accurately determine the cause of the malfunction after complete diagnosis in a specialized service center for the repair of automotive air conditioners.

At the bottom of the rear compressor cover, an emergency pressure reset valve is set. In the case of pressure growth in the system in the failure of a pressure sensor or other abnormal situations, when the installed maximum pressure of the valve membrane is destroyed and part of the refrigerant is ejected to the street. As a rule, after this, the emergency valve does not have sufficient tightness. Therefore, after eliminating the causes that caused pressure and reset the refrigerant, the valve is subject to a mandatory replacement.

When the valve is triggered, the refrigerant is unexpectedly ejected by strong jets in all directions. To prevent injury, people were closed by a cap.
Conductor (air conditioner radiator) multithreaded type is located in front of the engine cooling system radiator. It is attached using brackets to the cooling system radiator. Condensor cells are made of flat thin-walled aluminum tubes with internal longitudinal partitions for rigidity and outer fins to improve heat exchange. Aluminum tanks, with flanges for connecting pipelines and receiver. In height, the tank is divided into sections, therefore, passing through the condenser, the refrigerant flow changes several times the direction. In condensor, the steam condensation of the refrigerant compressed by the refrigerant compressor and the heat of heat released into the surrounding air occurs.

When the air conditioner is turned on, the engine control unit turns on the power supply circuit of the electric fan of the engine cooling radiator, which improves heat exchange in the condensor and reduces the pressure in the air conditioner system.

At least once a year, it is better before the start of the summer exploitation, wash the fins of the cells of the condenser from the nanice dirt, dust and antifungal reagents B. This will improve heat exchange, reduce the pressure in the system and increase the service life of the system elements.

Do not use condensor for washing installations with water jet under high pressure. This may damage in thin-walled feet of fins. Even with a regular car wash, the need to replace the condensor arises much more often than I would like. The fact is that he first assumes the flow of antifungal reagents, dirt and pebbles from the road. It is thin with the walls of the tubes ... In most cases, the condenser is damaged by corrosion to the third-fourth year of operation.

If the corrosion is disturbed by the tightness of the condensor, then repair it is more expensive. Even if the argon welding welker succeeds in patching the hole, there is soon the appearance of leaks elsewhere. By the way, the pressure in the system on hot days can reach up to 25-28 bar.

In addition, the complex structure of the condensor tube should be taken into account: along it is divided by partitions to the channels, so the likelihood is great that after welding, part of the channels will be blocked. Accordingly, the power will fall and the work of the air conditioner will deteriorate, especially in traffic jams and in hot weather.

After each experiment with the latch of the condensor, it will be necessary to pay for the removal of the installation, welding of the condensor and refueling the refrigerant system. So it is better to immediately install a new condenser. Instead of an expensive original, it is quite possible to buy a cheaper condenser from authorized spare parts manufacturers.

The evaporator is located in the heating system and air conditioning system. The evaporator is made of aluminum tubes with outdoor fins to improve heat exchange. Passing through the tubes of the evaporator, the boiling refrigerant actively absorbs heat

From the air that blows out the outer fins of the tubes. The air is cooled and the fan is supplied to the interior of the car.

When cooled through the air evaporator, the water vapors contained in it are condensed.

Condensate through a drainage tube connected to the body of the heating unit block ...
... and extended through the plastic adapter at the bottom of the right side of the engine shield, merges under the bottom of the car. With high humidity of the surrounding air under the car, water can be formed, which is an indirect feature of the condition of air conditioning.

During the operation of the car on a moist of condensate the outer surface of the evaporator, particles of road dust and dirt are sedired.
This layer becomes an excellent living environment and rapid reproduction of rotten bacteria and fungal crops. Over time, an unpleasant smell appears in the car. It is especially felt at the time of turning off the air conditioner and in wet weather. In order to minimize the risk of this problem as much as possible, when buying a new car, it is necessary to carry out the preventive processing of the evaporator with special chemicals, regularly replace the cabin filter and clean the drainage tube. If, despite the measures taken, the smell still appeared, contact a specialized service for repair of automotive air conditioners for disinfection or washing the evaporator. With very strong pollution, the evaporator will have to be replaced.

On the side surface of the evaporator there is a flange for mounting the thermal control valve.

The block-type thermostatic valve is located in the evaporator case. The valve is attached to the pipelines and evaporator using flange connections. Having passed through the throttling hole in the valve body, the liquid refrigerant sharply reduces its pressure and begins to boil. In the valve body, an adjusting element is installed changing the flowing section of the throttle opening depending on the pressure and temperature of the refrigerant. The adjusting element is configured at the factory and during operation the adjustment is not subject to.

Receiver-desiccant is installed on the condense on the left side and is a collapsible block. Inside the case there is a filter element (cartridge) filled with desiccant granules (silica gel). A liquefied refrigerant passing through the receiver is cleaned from possible impurities, dirt and moisture. At the top of the receiver case, a hole is located to replace the filter element.

In the case of repair or replacing the elements of the air-conditioning system, if it was in the open state (any nodes were removed, pipelines were destroyed, etc.), the cartridge of the receiver-desiccant is to be replaced. Otherwise, after refueling the refrigerant system, the acids can be formed inside the system, which destroy the parts of the air conditioner from the inside.

Flexible insert hose design: 1 - outer protective sheath; 2 - fabric cord power frame; 3 - plastic sealing layer; 4 - internal oil resistant layer

Pipelines connect all the elements of the air conditioning system into a single hermetic circuit. Pipelines and fastening flanges are made of aluminum alloys.
Wrap metal parts of pipelines from dents and beggars. Any narrowing of the pipeline cross section leads to a decrease in system performance.

To connect the intercommunicative elements of the pipeline system in some areas are supplied with flexible inserts from synthetic materials.

In places of compounds of individual elements of the system, sealing rings of a round cross section of neoprene are installed. During the repair of the system, when separating pipelines, sealing rings are subject to mandatory replacement. Threaded pipelines tighten the recommended point. Weak or excessively severe tightening leads to deformation of the sealing surfaces and refrigerant leakage.

Service valves for connecting diagnostic and filling equipment are located on pipelines.

So arranged on pipelines, service valves of high a and low-d lines of pressure.
Valves are closed with threaded caps to protect them from dirt.
Sloves are installed in the valves, similar in design with spools of tires of wheels, but differ from them.

Special key is used for turning and screwing the spools.

Check the presence of refrigerant in the system by pressing the spools of the service valves are prohibited, since after such an inspection, the valve spool can not fully close and refrigerant leakage will occur from the system!

The pressure sensor is installed in the motor compartment on the high pressure line pipeline.

By sensor signals, the electronic motor control unit turns off the air conditioner compressor when the system is deployed or an emergency increase in pressure in it in order to protect the compressor from overloads.
The control unit of the ventilation system, air conditioning and heating and car heating is installed on the instrument panel consoles.

Air temperature sensor in the cabin

Located in the front panel of the control unit, if the climate control system is installed on the car. To exclude incorrect readings of temperature values \u200b\u200bdue to the effect of heated elements of the panel, the sensor is equipped with a compulsory blowing system. The system provides a uniform air duct from the front of the car's interior through the sensor housing. For normal air movement, protect the input hole of the sensor housing from any solid particles or fluid. This is especially true of cases of chemical cleaning of the cabin. During the cleaning of the salon, the vacuum cleaner is strictly forbidden to bring the suction tip of the vacuum cleaner pipe to the sensor inlet. With a difficult airbone through the sensor housing, the normal functioning of the automatic climate control system is broken.

The outdoor temperature sensor, although it is located in the front of the car behind the radiator veneer in the solar radiation and the ventilated place is exposed to the effects of such factors as warm air from the engine and radiation from the heated asphalt. Therefore, its testimony can sometimes be somewhat overestimated, especially after a long idleness in traffic jams. The appearance of the outdoor air can be considered correct when driving at a rate of at least 40 km / h for at least 10 minutes.
To improve the efficiency of the climate management system and a more comfortable distribution of air flows in the cabin, a solar illumination sensor is installed. Depending on the degree of heating the cabin with the rays of the sun along the sensor signals, the air flows are sent to the head or foot of the driver and the front passenger. The sensor is located on the instrument panel near the windows glass.

Refrigerant. The system is refilled by the HFC134A refrigerant (R134A). The refrigerant added special oil for lubrication compressor. It is strictly forbidden to use refrigerants and oils of other types in the system.

During the operation of the automotive air conditioner, situations occur periodically when maintenance of the air conditioning system or its repair is required. This uses modern diagnostic and repair equipment. The most common situation is the deployment of the system and the exit of the refrigerant.

To detect leakage places, highly sensitive halogen leaks-swelkers are used with sound indication.

In some difficult cases, the so-called method is used. Ultraviolet diagnostics of the tightness of the autoconditioner system.

The method is that a special dye is introduced into the microDosis system.

In places of microtheps, the dye together with the refrigerant gradually goes to the outer surface of the system elements.
During the inspection of the system, the dye begins to glow (fluoresce) under the action of ultraviolet rays of a special lamp ...
... and refrigerant leakage places are visible.

It should be noted that the dye does not have any negative impact on the system. It can be in a refrigerant and circulate on the system how long and serve his service only when the leakage occurs.

After repairing the autoconditioner, it is necessary to evaporate and refuel the system with a corresponding refrigerant (R134A). The volume of refueling the auto air conditioner for each car model is individual.

To carry out high quality refueling of the automotive air conditioner are necessary:

Precision manometer blocks with special connecting tips:

Two-stage vacuum pump for complete air removal and water vapor from the system;
- High-precision (division price no more than 5 g) scales for dosing the refilled refrigerant.
Due to the specific features of repairing the air-conditioning system, this section describes only the work on the removal and installation of individual elements and the system control unit. Works associated with refueling the refrigerant system should be carried out in specialized service centers.

The air conditioning system is refilled by a high-pressure refrigerant. The liquid refrigerant hitting the human skin causes a strong frostbite, so all the work related to the service, repair or dismantling of the elements of the air conditioning system, spend whenever possible in specialized service centers equipped with professional technological equipment. When carrying out work on your own, take precautions.

Features of the device of the ventilation system

The vehicle ventilation system is applied by car. The outer air can enter the interior through the windows of the doors when the glasses are lowered ...

And through the air box grille, located in front of the windshield in the air intake. The air from the air intake is fed through the air ducts to the car's salon through the winding winding nozzles, side and central nozzles, through the lower nozzles of the heater housing.

The air from the street entering the car is purified from dirt particles and pollen in the cabin air filter, placed in the body of the climatic unit.
The filter element of the air filter should be replaced in accordance with the deadlines for prophylactic work, exhaust ventilation is carried out through the grids, which are made in the rear trunk facing.

When the goods are placed in the trunk, if possible, try not to illuminate the ventilation grids, leave a small gap between the luggage and the facing panel. The effective work of exhaust ventilation improves the temperature in the cabin and reduces the formation of condensate on windows windows.

From the side of the exhaust ventilation holes, closed with deflectors with petal valves, which are installed in the back of the body, in the cavity of the rear bumper (view with the removed rear bumper).

Security Rules for the repair and maintenance of the air conditioning system

1. The refrigerant is a chemical composition requiring careful appeal to avoid harm to health.

2. It is necessary to work in a well-ventilated room and avoid inhaling the chest of refrigerant.

3. When performing work related to the depressurization of the air conditioning system, you must always wear safety glasses and wrapping fittings, valves and connections with clean cloth.

4. It is forbidden to carry out welding work by car near the units and pipelines of the air conditioning system.

5. It is forbidden to curb flexible inserts of pipelines (hoses) by a radius, less than four diameters of flexible insert.

6. There should be regularly inspecting the hoses for the appearance of cracks and scuffs.

7. Before disconnected of the air conditioning pipelines, it is necessary to remove the entire refrigerant from it.

8. Turning the threaded connections of the system elements should be slowly. Do not bring the face and hands to the place of separation to avoid injury when there is a liquid refrigerant residue in the system.

9. When detecting the pressure pipelines during disconnection in the system, refrigerant must be removed from it.

10. After separating any area, it is necessary to immediately close the holes with caps or ribbon. This will prevent the moisture and dirt entering the system, which the ILO cause the failure of the pumping part of the compressor.

There was a time when not many cars drove with closed windows. And, as a rule, their owners were wealthy people. Only they could afford comfort at the hottest time of year. This time dictates its own rules. And today, almost every car is built in air conditioning and climate control. Volkswagen Polo cars Sedan new configuration are equipped with a climate control function that has fully justified in the first years of operation. Use it is a pleasure.

What is climate control

Climate CONTROL The block is located in the front of the car. The design of the appearance is slightly different. The rear can perform, subject to the placement of the board lying, or be shorter. At the same time, the direction and connections are identical in them. They have the same connectors, interchangeable. On functions all blocks are the same. Management can be both mechanical and sensor.

There are all elements of the control climate, connected by aluminum tubes. They create a hermetic closed circle. Therefore, when repairing malfunctions or planned diagnostics, special attention should be paid to the area where there is bends. Since bends can disrupt the air conditioner and provoke serious breakdowns.

Problems arising from operation

How many positive feedbacks did not speak about the system, but, like the whole technique, it is characterized by breakdowns and malfunctions. When some function does not work, you need to diagnose and correct breakage. Several typical reasons for which the problems of operation of the control in Volkswagen Polo arise:

• Circulation of coolant on the system is the main task of the compressor. With full work, while turning on the air conditioner can be heard. When the vibration or the coupling appears, it starts to creak - this is a reason to diagnose and eliminate the breakdown. If there was no click, it was possible to flow fluid, the pressure sensor broke or the compressor is blocked.
• Radiator corrosion. I recommend it to clean, at least once a year. Cleaning should be taken carefully, so as not to damage the ribs of the design. Unfortunately, even the maintenance relationship during washing cannot prevent the emergence of corrosion. After a few years, fine holes begin to appear. Holding them, new, in another place.
• Contamination of coolant dust and dirt in connected between them, block and receiver desiccant. The process occurs due to the interaction of silica gel granules with a cartridge. When repairing the air conditioner, the filter must be changed.

Repair and diagnostics of the system

Prevent the breakdown is much easier than to eliminate it. Treatment of the system always begins with its diagnosis. In order to support the climate control in working condition, you need to regularly, according to the instructions, clean the filter and change the liquid.

The first thing to check in the climate installation electronics is the presence of faults. If you have errors, go to the measuring blocks and view the readings from 11 to 16 block. Calculated and current values \u200b\u200bmust match. If they float, the damper must be cleaned or change. When the temperature changes to the climate control, the valve value changes.

After this is adapting the control climate. It occurs within 30 seconds. To implement it in the basic parameters, you need to select 1. Then read and enable.

If, in the diagnostic process, the compressor breakage was detected, it was possible to solve it using the wizard on the observation site. Cooling fluid from the system, shut down the pads and wires. It is worth paying attention to the state of the belt and bracket. If they are broken, then to be replaced. On the polo sedan for the compressor is provided for an emergency valve. When the pressure significantly exceeds the norm or the sensor stopped working, the valve is broken and removed from the cooling fluid. Therefore, after eliminating breakage, the valve must be changed. Change details better than new, and not used.

Refueling the coolant should be carried out on time in specially designated valves. In addition, it is worth watching the interior temperature sensor. It is important that dust and dirt did not fall into his openings. This entails the failures of the device and incorrect instrument testimony.

Heating, ventilation and air conditioning

The car, depending on the configuration, can be equipped with a system of heating, ventilation and air conditioning with manual control and automatic climate adjustment in the cabin - climate control system. The air into the car's salon can act through the central and side deflectors located on the instrument panels, as well as through the air ducts - to the feet of the driver and passengers.
The cabin air purification filter prevents dust and harmful particles in the air in the air.
It turns out the air from the salon to the trunk through the ventilation grids located in the shelf under the rear glass. From the trunk, the air comes out through the grilles under the rear bumper.

Side deflector of heating, ventilation and air conditioning system: 1 - lever changes in the direction of air flow direction; 2 - the intensity regulator of air intake.

Central heating, ventilation and air conditioning system deflectors.
The control unit of the heating system, ventilation and air conditioning is located on the center console of the instrument panel.

The control unit of the heating system, ventilation and air conditioning (on car controlled vehicles): 1 - air temperature controller; 2 - switch mode of the heater fan operation; 3 - air flow distribution regulator; 4 - the air conditioner switch button; 5 - Air Recycle Recycling Switch.
By turning the handle of the air temperature controller 1, change the temperature of the air entering the interior. To increase the air temperature, you must rotate the knob of the regulator to the right, in the red sector of the scale, and to reduce the air temperature - to the left, in the blue sector. The intensity of air supply to the salon is regulated by turning the handle of the fan operation mode switch 2. In this case, one of the four fan rotation rates are turned on. Turning the knob of the switch clockwise, increase the speed of rotation of the fan. Air flows entering the salon can be adjusted. The flow distribution regulator 3 sets the following direction of air multiple air in the cabin:
- Air flow through deflectors in the instrument panel enters the top of the car's interior;
- The air flow comes only to the driver's location zone and passengers;
- the air flow enters the location zone, as well as to the lattices of blowing windshield;
- The air flow comes only to the lattices of windshield blowing.
To enable air recycling mode, press the switch button 5. In this case, the indicator lights up the button. To turn off, press the button again. Air recirculation mode (termination of the outdoor air supply to the cabin) It is recommended to use if necessary to quickly reduce or increasing the air temperature in the cabin, as well as when driving on dusty terrain or in a dense traffic flow to avoid dust, exhausted gases and unpleasant odors.
