If in the car (prior interests us most at this moment), then the driver and passengers this situation delivers a lot of inconvenience. In the summer, this problem is irrelevant, because no one is particularly worried about what the heater is located. And only with the onset of cold weather, the overwhelming number of motorists is puzzled by the problem of the non-working heating system.
Possible causes of cold air
Common is the situation when blowing cold air From the stove of priors, the reason for this may be not alone. It is in determining a malfunction and is the main problem. The reasons for not blowing the stove on the prior may be somewhat:
- The engine cooling system breakdown is the most common problem. It is with it that it is worth starting diagnostics. In most cases, the stove does not turn on on the prior for this reason.
- Highly to be replaced with a new one. This procedure should be performed every six months, without waiting for the moment when the stove starts blowing cold air.
- The stove is bad on the prior, perhaps due to the damper, which can be in the jammed state. It can not open completely, blocking the path of hot air flow paths.
- And the problem may be in the motor deuctor. It is necessary to check it on working capacity.
- If the stove does not work on the prior as you would like to pay attention to the control unit.
- The temperature sensor may also have a negative impact on the health of the heating system. To decide on this moment, you will need to disable the sensor and see how the heater will behave.
We carry out a comprehensive diagnosis
Not so easy. Even experimental motorists It is not possible to cope with this task quickly. In order not to make such a large volume of work invested, it is better to first diagnose the heating system. It is necessary to act as follows:
- Take the channels through which the cooling fluid comes to the heater. They must be warm when the stove is turned on. In addition, when pressed on trunk rubber hoses, resistance should be felt. If the resistance is not felt, you can talk about the fault pump pump. This mechanism is responsible for creating pressure of fluid flows required for normal work heater.
- A small secret may be useful to owners of the Lada Priors: The stove blows with cold air for a long time and warms up not as fast as I would like? Then you can try to fill the coolant to the bottom mark in the tank. In this case, the liquid will warm up faster. If this method is practiced, it will be necessary to constantly check the level of the coolant.
- If working, you can talk about the problem in the bearing, which is located on the electric fan. It is impossible to ignore this situation, because in the future it can jam the fan and repair will gain much larger scales.
- Do not work stove? Perhaps the problem is hidden in the F9 fuse with a par value of 25 A. Its functions are to protect the power electrical heater lines. Dropped fuse must be replaced. If a similar situation arises with enviable constancy, then it is necessary to check all electrical circuits Heater, insulation windings on the fan and the presence of power supply chain overload.
No heating at idle
This question is not in vain for a separate consideration, because it worries many motorists and the solution to the problem can be much more complicated than expected. So, you have a prior, does not warm the stove on idlingAlthough when moving the car, the interior is heated in normal mode. Here you can also identify several possible reasons:
- Insufficient coolant level.
- Leaks that lead to a decrease in the level of antifreeze.
- Availability .
If the first two problems can be easily diagnosed and eliminated, then the case is much more complicated with air traffic. If you excluded the first two reasons and still does not heat the stove priors at idle, it is necessary to eliminate air traffic. It is necessary to act as follows:
- We dismantle the screen from the engine.
- The clamp is lowered, after which it is necessary to remove the heating tube of the throttle node. Of the two choose any.
- On the expansion tank we unscrew the lid. On the neck we place a clean rag and start blowing in expansion tank. The air supply must be carried out until the coolant will begin from the tube that has previously removed.
- We immediately wear a tube on the fitting and thoroughly tighten the clamp.
- Install the screen.
If the option with blowing a tank is not suitable, you can go to another way. Warm the engine so that the pressure in the heating system has risen. After some time, the car and remove the hose from heating the throttle node. In this case, the cork from the tank is not required. As a result of high pressure through the tube, coolant will be supplied. It remains to put the tube on the fitting and tighten the clamp.
Now it should not cause difficulties the stove of the prior, faults how to eliminate, you know, and also to diagnose and identify the source of problems. Let the heater on your car always be turned on, working properly and give comfort, regardless of the weather outside the window.
Why the stove does not work on the Lada Priora
Lada Priora is in many ways similar to his progenitor VAZ of the tenth family, including the heater device. The manufacturer decided to leave the principle of the stove, replacing only some elements new. Together with this, Lada Priora inherited acquaintances, for example, when the stove does not heat and blows with cold air.
Heating system elements (stoves)
The fact that the stove "Priors" is 95% similar to "dozen" can be seen by catalog numbers:
- Heater assembly (2170-8101012 or 2111-8101012-10).
- Air Flow Distribution Motor (2170-8127100). Distributes air flows to feet / face / windshield. It is inside the torpedo.
- Air temperature sensor in the cabin (11186-8128050). Located on the ceiling.
- Heater controller (KUO) or stove control unit (21703-8128020). The block on which the driver sets the parameters of the stove. Located in the panel.
- Resistor Extension or additional resistor (2123-8118022). Determines the speed of rotation of the stove fan. Fastened in the engine compartment.
- Heater Electristant (2111-8118020). Located under the hood.
- Heater valve motor (2110-8127200). Distributes air flow into the salon (Street / Radiator stove). Inside the heater assembly.
- Air filter (2110-8122020).
- Radiator stove (2110-8101060). Located inside the heater.
A malfunction of one of these elements causes problems in the work of the stove.
Principle of work stove
To independently determine the problem of the heater, you should understand the principle of its work.
The heater controller receives a signal from the temperature sensor in the cabin and compares it with the temperature that the driver put. If there is a difference, then Kuo sends a signal to the stove motor deuctor (located under the hood) so that it is closed or opened to a certain amount of the stove valve for greater supply of cold or hot air.
After setting the desired fan speed of the stove, the heater controller sends a signal to an additional resistor (in the engine compartment), which, due to the built-in resistance, sends a corrected signal to the fan. On the maximum speed The resistor is not used and the electric fan rotates at the maximum speed.
Air direction (face / feet / windshield) Determines the driver, exposing the required value to the CUO. After that, the signal comes to the airflow distribution motor (inside the panel / torpedo), which moves the flap in the desired direction.
If the stove blows with cold air (does not warm)
The reasons why the stove "Priors" is bad may be somewhat (in brackets there is a percentage of breakage based on the results of the survey among the owners of this car):
- The malfunction in the engine cooling system (the cutting radiator is cold and cannot give heat). Turn both heater radiator hose, they both must be hot. Sometimes the reason lies in the radiator itself (marriage, not perfectly productive) (8%).
- Dirty salon filter. Try to remove the filter and check the operation of the stove (2%).
- The stove damper does not work, it is simply jammed (17%).
- Faulty stove motor (16%).
- Faulty air temperature sensor in the cabin. Try to turn it off on time and check the operation of the heater (6%).
Paragraphs 3-6 may also be a reason when only hot air from the stove is constantly blowing.
Mode switch does not work (face / feet / glass)
Possible causes (in brackets indicated percentage of breakage based on the results of the survey among the owners of this car):
- Defective heater controller (13%).
- Faults of the air flow distribution inside the cabin (8%).
The stove works only in 4 position
If the first, second or third position of the stove does not work, therefore (in parentheses the percentage of breakage is indicated according to the results of the survey among the owners of this car):
- Faulty stove resistor (7%).
- Faulty heater control unit (13%).
If noise stove
The electric fan bearing is buzzing (17%). Also additional noise May cause a dry leaf that fell under his blades.
The stove does not turn on
- Fastened the fuse to the F9 (25a) stove.
- Faulty heater control unit (13%).
Conclusion
Car heater - not simple system, but according to the reviews of the owners - not quite reliable. Try to determine the fault of the stove starting from the check, and then the remnal details on knowingly sound. Do not forget that the reason may be in a bad contact or cliff of car wiring.
We have already written that the heater of the VAZ 2110 and Lada Priora is very similar, perhaps you will find a lot of useful on their website. And what problems did you test with the stove? Did you have solved them? By participating in the survey, you help other motorists to determine the reasons. Read also other articles on the repair and operation of Lada Priora.

By car "Lada Priora" the heater is not just a stove. In fact, this is a full-fledged climate control device. In terms of its characteristics, the stove "Priors" is not inferior to foreign devices of this type. But as well as all the mechanism, the stove "Priors" may fail. In this article, a review of the heater and features of its repair.
Features of the stove priory
Climate control of this car in some options is designed to install the air conditioner. Therefore, the device of this device in this case is a little different than that of the VAZ-2110 heater. This article discusses standard option heater. Although they have a lot in common. The stove (heater without air conditioning) "Priors" includes the following large nodes:
- Case stove.
- Air duct system.
- The electronic unit Heater control (ECU) with control console.
This is, so to speak, three basic nodes. All of them, except for the ECU, disassemble and consist of various subsystems. According to conscience, the control unit, with a big desire, can also be disassembled. But it is not worth doing this. This is thin electronic deviceAnd only a specialist can repaired it. But with two others there are options.
Housing
After the control unit, the stove body is the most complex object. The fact is that it includes several elements:
- Corpus consisting of two parts.
- Purchasing electric motor with fan.
- Small heating radiator with nozzles.
- Variable resistor.
- Heater air damper.
- Microworoscottor, heater damper drive.
- Cabin filter.
Attention! Equipped with air conditioning "Priora" has additional elements as part of climate control, but this is a separate topic that is not affected in this article.
All listed elements sometimes fail, and it is quite possible to replace them independently, without resorting to the services of a specialist.
Location and access
As with the VAZ 2110 models and modifications, the heater is located outside the cabin. It is in the engine compartment. Right under the windshield. From the engine, it is separated by a special moto-cardboard partition. And on top is closed with a plastic dual casing, which hides this compartment, in which the heater is installed, also the brake vacuum and the engine cleaner drive.
To access the "Priors" stove, these elements need to be dismantled. Disconnect the cooling system hoses. Unscrew the 3 fastening nuts and remove the housing. This process is repeatedly described and shown in the attached video. Therefore, it is not worth repeating here.
Cabin filter
Most often, fails, or produces its resource precisely this part. He simply clogged with mud and dust. It is expressed in a decrease in the intensity of the fan operation. Sometimes, it is contaminated to such an extent that the stove fuse burns. The load on the electric motor grows so much that the fuse simply "knocks out". The reader is located at the air inlet into the heater. Near the right wing of the car. It is closed with a decorative plastic lid.
Important! Do not wait for pollution. It is recommended to periodically replace the filter 2 times a year. In the spring and autumn.
Electric motor stove
To remove and replace the stove electric motor, on the "Prior" without an air conditioner, you have to dismantle the heater completely. Or at least a little to push it forward. The fact is that this motor is located on top of the stove "Priors" and is under the supporting part of the windshield.
Resistor heater
This element serves as a peculiar fan rotation speed switch. It has several resistance steps. Each step is speed. Malfunction of the resistor to determine easily. If none of the speeds do not work besides the maximum, then in 99 cases out of 100, it is the resistor. And only in 1 switch, in the control unit.
It is also on top. But it is quite easily removed without dismantling all the stove. It is enough to remove the connector and unscrew 1 screws fixing resistor. And that's it.
Micromotor
In the climate control system "Priors" there is no option to disconnect the radiator from the car cooling system. That is, the hot liquid is constantly drawn. Cold air supply is provided by the direction of air flow from the fan using a special damper, which overlaps the radiator and passes the flow by.
Moves this detail Special device - microworoscottor. It is controlled by the control unit. It can also be replaced without removing the fully heater. Although it is located between the vacuum brake amplifier and the stove case. However, its diagnosis and replacement has features that will be described in a separate topic.
Air damper heater
One of the key devices of the system, despite its simplicity. The flap moves on the axis rotated by the micromotor. Located inside the stove "Priory". Therefore, for repair or replacement, naturally, the stove must be dismantled.
Attention! The repairs needed the first samples of dampers made of plastic. Currently, the "priors" put flaps from aluminum. Therefore, there is no need for their repair and replacement.
However, if all the same in the presence of a "prior" with a plastic flap, then the drive protrusion can break it. It is quite simple to determine it. Turn on the ignition, and removing the casing separating a niche with the heater from motor compartment, To watch the gearbox, switching the thread control handle from hot to the cold. It can be seen that the drive rod rotates, and the temperature does not change. So, the damper must be changed. This procedure will be a separate article.
Radiator
And the main heating knot is the stove radiator. It is located just on the right side, near the damper drive. Naturally, for his replacement, the stove "Priory" will have to shoot. It is attached to the casing of three screws. And after removing the heater it is easy to pull out twisting these screws. Clear planting place Radiator and install new ones. This item is made of plastic and aluminum and repair is not subject to repair. Only replacement.
Important! When replacing the radiator, be sure to use a special adhesive sponge, it is glued to the sides and the end side of the radiator. This is necessary to avoid the formation of cracks from shocks about the stove body.
Determine the flow of the radiator is quite simple. Although the coolant coolant on these heaters does not fall into the salon when leakage from the radiator, but when it appears, with any position, the evaporation damper is instantly fall on the windshield. They form a clearly prominent muddy film with a sharp smell of toosol. it clear stove radiator replacement signal.
Electronic heater control unit
This is a mini-computer with its program. The convenience is that it is initially connected to the channel computer diagnostics. Therefore, many faults can be revealed to connect diagnostics to the diagnostic "Priory" diagnostic connectors. But this interesting topic will be described in a separate article.
Useful video on the topic "Removing the" Priory "stove:
The main reasons for the breakdown of the stove in the lade prior:
- if the air hit the heating system at the moment when you were replaced by a coolant or damage to the main block of cylinders;
- if the stove with a quick movement warms badly, and at low speed well, then the problem of the thermostat in the open position;
- if the stove radiator is clogged, as insects, leaves, dust, sealant, water or poor-quality toosol can get there.
- in the case of pollution of the salon filter;
- if the fan itself came out;
- with wear of bearings or brushes;
- problems with electronics;
- if the radiator flap is damaged, there is no air access;
- the heater crane lever worked, as the gum were dry, and in this case it is necessary to replace the new together with the stove radiator;
- the upper nozzle broke down, it is not subject to repair, only replacement for a new one;
- may break the stove control unit and interruptions in the fan operation will appear;
- fault of the air temperature sensor.
For all the existence of the car, Lada Priora is constantly being improved. All new models appear.
For example, the hatchback priora car has maximum complete set: ABC, climate control, heated, parking sensors, staff music and much more. Its advantages in the engines, fuel consumption, reliability, good stove and start in any frost. The seat behind the wheel is very comfortable - the back does not get tired, and the legs do not register. Previously, there was one engine in the lades - a 16-valve, outstanding 98 horse power. Now Lada Priora consists of two 16 valves and gives 98 and 106 horsepower.
Bad warm stove Lada Priora with air conditioning and without
Nowadays, the tie of prior, equipped with a system of air conditioning, will not surprise anyone. Air conditioning is an additional installation that increases the cost of the machine. It can be included in the package, as well as it can be purchased after buying a car. To come with air conditioning, this car has become quite recently.
It is worth thinking when buying a car, whether the air conditioner is needed complete. Suppliers of air conditioners on this car are Panasonic produced by Taiwan or Korean Hello. These are both types of air conditioners with their details are designed by contractors and on appearance They look in principle equally. In the case of replacing the filter or belt in the air conditioner, it is necessary to know its model and the size of the filter.
