Location and wiring diagram
Circuit breakers of the Opel Astra G car are located in separate mounting blocks for the electrical system, which are installed in the instrument panel and the engine compartment. The last block contains fuse-links and relay mechanisms for the most current-loaded electrical circuits. This position of the safety elements allows for the reliable operation of the car's electrics. Both blocks in machines prior to 2001 and later have differences in the location of the components. The designation of fuses and relays is printed on the wiring diagram located on the rear cover of the passenger compartment.
Installation diagram of elements in the cabin block
On Astra cars produced in 1998, 1999 and 2000, on the left side of the block located under the hood, there are F1-F5 sockets for more powerful fuses. To the right are two rows of vertically installed fuse-links marked F6-F23 and F24-F41. Above the fuse holders there are designated places for spare parts and plastic pliers that are used when replacing parts. In the same block, there are eight more fuse-links, which are the same for all machines. Opel astra G and arranged vertically in a row.
The mounting block in the passenger compartment contains fuses and relays. The fuses are rated for currents from 7.5 to 40 amperes and are located in two rows on the bottom of the unit.

Fuse decoding
A full description of the fuses for the Opel Astra G is given in the tables in the photo.
Fuses in the old block, part 1 Fuses in the old block, part 2 Fuses in the old block, part 3 Fuses in the new block, part 1 Fuses in the new block, part 2 Fuses in the new block, part 3
The purpose of the eight fuse-links in the block under the hood of the car is as follows (from top to bottom, using the example of a 2003 car):
- 1 (60 A) - ignition switch circuit;
- 2 (60 A) - general protection of the fuse box in the passenger compartment, engine control mechanism;
- 3 (60 A) - relay in the car dashboard;
- 4 (40 A) - protection of electric motors of the cooling and air conditioning system against short circuits;
- 5 (60 A) - ABS unit;
- 6 (30 A) - chains of engine control units (fuel pump, injection system, ignition, etc.);
- 7 (80 A) - power steering;
- 8 (40 A) - protection of electric motors of the cooling and air conditioning system against short circuits (only on machines with air conditioning).
Relay type and purpose
The decoding of the relay of the mounting block of the early sample is as follows:
- 1 - coding connector;
- 2 - horn relay;
- 3 - turning on the high beam;
- 4 - rear wiper activation relay;
- 5 - heated mirrors;
- 6 - turning on the front fog lights;
- 7 - activation of the rear fog lamp;
- 8 - right direction indicators;
- 9 - left direction indicators;
- 10 - built-in telephone relay;
- 11 - reserve;
- 12 - front wiper activation relay;
- 13 - reserve;
- 14 - power supply for heating rear window.
The turn signal relay can be made in a common housing or in separate parts.
The video from kivalssl1 shows the installation of the relay of the "comfort" unit in the mounting block Astra G.
On models 2001, 2002, 2003, 2004 and the following years of release, the purpose of the relay has changed slightly. Relay 11 was added, which is responsible for transmitting signals from wheel rotation sensors and relay 13 for interior lighting. On the side of the mounting block, a "comfort" device is inserted, indicated in the diagram by the number 15.
Below is the designation of several more relays in the engine compartment block.
How to replace it yourself?
No special tools are required to replace elements in the interior mounting block. All you need is a slotted screwdriver and a set of new fuses.
Replacing fuses
Guidelines for replacing defective fuses, for example, those responsible for the operation of the stove or cigarette lighter, are as follows:
- Switch off the vehicle ignition system.
- Open the small folding box on the dashboard, located near the knee of the driver's left leg.
- Press on the plastic clips on the sides and remove the box body from the frame.
- Unscrew the four slotted screws securing the frame.
- Remove the mounting block from its place by pulling on the bottom.
- Replace defective fuse. For this, the damaged fusible element must be removed from the socket. The mounting block comes with small plastic tongs. They need to clamp the fuse case, pull it out with seat and insert a new part.
- Visually check the condition of the remaining fuse-links.
- Reassemble.
It is important to take into account that the new fuse must have the same rating as the failed one. In the absence of such a detail, an element of slightly higher value can be used. Only first you need to check the operating condition of the circuit, for this you need to install a fuse from any other slot with the required rating. If the fuse remains intact, then a part with a higher rating should be put in its place. But as soon as possible, it should be replaced with a part with a standard value. Because long-term operation An inappropriate fuse can damage the vehicle's electrical systems and cause fire. If, after replacing the fuse, it immediately fails, then it is necessary to find out the cause of the overload in the electrical circuit.
The process of replacing fuses on more modern Opel Astra H 2008 or Opel GTC 2012 is identical to the above.
Replacing parts in the engine compartment is even easier. To do this, it is necessary to unfasten the plastic covers of the blocks and replace the damaged fuses or relays.

Block replacement
When operating the vehicle, situations may arise as a result of which the mounting blocks are severely damaged. In this case, the owners are forced to change the entire blocks, buying new parts or using ones taken from other machines.
This replacement requires experience with electrical systems, as well as various tools and devices, so this procedure is best carried out in a specialized workshop.
But in the case when a decision is made to replace the unit inside the cabin with your own hands, the sequence of actions will be as follows:
- De-energize the vehicle by disconnecting battery... Before that, you need to make sure that the code for the standard audio system is safe.
- Access the mounting block by analogy with the procedure for replacing fuses.
- Disconnect the pads and wires from the old block.
- Visually compare the appearance of the old and new unit, check the identity of the fuse and relay ratings.
- Install the new mechanism in place, making sure to match the colors of the cables.
- Connect the power supply to the vehicle and check the functionality of the systems.
- In the event of inoperability of components or blown fuses, it is necessary to find out the causes of the problems.
Free collection of all fuse diagrams Opel models... Opel cars have a lot of electrical circuits that are protected by fuses, thanks to which unpleasant and sometimes even dangerous situations can be successfully avoided. It will be unacceptable to simply close the burnt-out fuse-links with "bugs" made of thick wire. But even a working fuse can bring surprises - due to weakened holders or oxidized tips of the fuse, the contact part "burns out", as a result of which the contact resistance increases and, as a rule, heating, then the contact deteriorates even more, there are problems with the operation of the car's electrician ... We recommend that you inspect and clean them at least once a year. It is recommended to keep several spare fuses in the machine at all times. For storage in a fuse box located in engine compartment often, appropriate holders are provided. You can clarify the wiring diagram in.

Opel Astra H. Malfunctions oxygen sensor
The main malfunctions of the oxygen sensor:
Heater malfunction;
-burning, contamination of the ceramic tip;
-oxidation, violation of contact.
The lambda probe can fail due to its service life (about 60-80 thousand kilometers).
The status of the oxygen sensor is also monitored by a self-diagnosis system. If a malfunction is detected, a warning lamp on the instrument panel comes on.
Indirect signs of sensor malfunctions - unstable operation at low speeds, increased consumption fuel and low dynamics. It should be remembered that these external signs accompany malfunctions of the injection system and malfunctions of the ignition system.
In addition to the listed system elements exhaust system, its other parts may be faulty: the exhaust manifold, the corrugation and the resonator. These elements can burn out, rust, receive mechanical damage, fail due to the limitation period of the elements. Signs of malfunction may be noise during the operation of the exhaust system, odor exhaust gases inside the car, drop in engine power, vibration and other negative consequences. If you find it difficult to determine the malfunction of the exhaust system of the car, then the best way The solution to the problem will be to contact the car service on Nagorny to identify the malfunction and repair the exhaust system of your car.
Oxygen sensor malfunction symptoms:
The consumption (consumption) of fuel by the car increases significantly;
- engine operation becomes unstable;
- premature failure of the catalyst.
The car moves with jerks on the road
- increased fuel consumption,
- the car is "stupid", does not drive well and picks up speed
- the motor runs unstable at idle
- immediately after stopping, a characteristic crackling is noticeable in the area of \ u200b \ u200bthe "lambda"
- during an external examination of the sensor, it turns out that it has heated up to a hot state (reddened).
In the presence of the above problems, it is likely that the oxygen sensor is out of order, it needs to be checked, it is quite possible that it needs cleaning or replacement.
The following reasons can lead to damage to the oxygen sensor:
One of the main reasons, especially relevant in our country, is the low quality of gasoline, the high content of lead in it.
- contact with the body of the oxygen sensor of brake or coolant
- an attempt to clean the probe without knowledge of the matter, or by means not intended for this
Replacing the oxygen sensor
Replacing a lambda probe on a car is very easy, especially if the sensor is located on the exhaust manifold (it is more convenient to get to it). It is better to change it on a well-heated engine, since cold metal is compressed, and the sensor often "sticks" to the manifold.
To replace you need:
Switch off the engine and switch off the ignition,
- disconnect the wires at the connector,
- use a wrench (sometimes a socket wrench is required) to unscrew the faulty sensor
- screw the new sensor into place as far as it will go, but without any extra effort
- connect the wires at the connector.
That's it, pretty basic. Now there will be no problems with the new sensor.
Most of the power supply circuits for electrical equipment in the Opel Astra are fused. In this article, we will describe in detail the Opel Astra N fuse box (diagram), its location, as well as the process of replacing the element.
[Hide]
What is it and why are we needed
A fuse is a device that protects consumers of electricity and electrical circuits from short circuits and system overloads. It contains an insulating body, fuse links, and a special terminal that connects the fuse links and the electrical circuit. In order to avoid overheating, some parts also include quartz sand.
The fuse box is needed in order to protect the system and prevent fire in case of a sharp increase in the current level. This happens due to the fact that they burn out first. Basically, such an item is disposable.
Location and layout
The most popular fuse location is in the interior or under the hood (they are located near the washer). Each car has its own layout, depending on the location (near the cigarette lighter or washer). The diagram is necessary in order to better understand the ongoing processes, as well as the principle of operation. Some types of cars (eg trucks) may have more than one fuse box, or even 4 or 5. They can also be scattered around the car, but this rarely happens.
Engine compartment fuse box
In an Opel Astra, there is not one block, but two. Their location is in the engine compartment and the passenger compartment (not far from the cigarette lighter). A diagram of the working processes in the Opel Astra and the elements protected by fuses is just below.
Removal and replacement process
The block described in this article has properties to burn out, or individual parts need to be replaced. How to determine what needs to be removed and what needs to be installed new?
Car enthusiasts often use such a simple method as simply pulling the object out, viewing it in the light, and if there is no significant damage, put it back in place. Under no circumstances should you check parts using this method, both in the Opel Astra H and in all the others! This method is very unreliable and questionable! After all, processes such as a burned-out jumper or an oxidized part cannot be detected by eye.
Passenger compartment fuse box
There is a method to check the integrity of a part in an Opel Astra car. Nothing needs to be taken out. Turn on the circuits that do not work (this can be a stove, a light, or a tape recorder or dimensions). Next, check the voltage with a probe, first at one end, then at the other. Suppose there is voltage at one end (output), but not at the other. In this case, the spare part is damaged. This check in the car is carried out very quickly - within one minute.
Replace the burnt-out part with the same one at par. The denomination increases only when you add something else to the chain that burned out. How to properly install a new part in the block? They are installed by analogy with the old ones. The only thing that it is advisable to check new parts before replacing. There is a method suitable for any system, no matter if they are located in the engine compartment or near the cigarette lighter. Thanks to him, you quickly check the item for quality, so that your Opel car Astra H was not injured.
So, tie the wires to the ends of the new part and one to the plus, the other to the minus.
Thus, a short circuit will occur. If the part is completely burned out, then the batch is really of high quality and you can continue the installation. And if the element began to melt, then it is undesirable to install this batch. In situations of overvoltage inside the car, they will also melt, and this promises that the electrical wiring will melt along with them, which will lead to serious consequences. So choose your fuses carefully, check in time and take care of your Opel Astra H.
Video "Replacing the Fuse"
We bring to your attention a video showing how to replace the washer motor fuse yourself in an Opel Astra car.
This model has been produced since 2004. For a long time of operation, the owners of this car have accumulated considerable experience in maintenance and repair. When faced with electrical problems, many drivers start to get lost in electronic systems, wires and connectors. And in this model, finding the cause of an electrical malfunction is not so easy even for trained people, because the fuses and relays of the Opel Astra H differ depending on the configuration.
Common problems, ways to fix them and diagnostics of errors - all this may be needed to fix Astra.
In the basic and full configurations, fuses and relays of the Opel Astra H differ in numbering. For example, in the trunk in the basic version there is a small fuse and relay box, and in the full version it is a full-fledged one. Under the hood, the fuse numbering of the basic version does not match the full one. This is due to the difference in electronic components and different electrical circuits.
This article covers the complete set of mounting blocks.
Trunk fuses:
1 (25 A) - power windows in the front doors... If the glass lifter of one of the front doors suddenly stops working, first check this fuse, then the wiring at the place where the door is opened, between the body and the door.
The wire could break off or the connector could oxidize. Remove the trim from the door and check the wires inside the door. Check ground (brown wire between body and door). With the trim removed, also inspect the hoist drive mechanism and check its motor.
If the window regulators do not work correctly, you can program them. To do this, disconnect the battery for a while, reconnect it, turn on the ignition, with the window closed, press and hold the window lifter button for 3-5 seconds. Press and hold the button for each door separately.
2 - not used.
3 (7.5 A) - dashboard ... If the devices or panel illumination do not work, also check fuse 18. It may be the board of the panel itself or the wiring connector on the back of it.
4 (5 A) - air conditioning system... If the air conditioner does not work, check also fuse 14 in this block and fuses 4, 20, 32 in the engine compartment, as well as relay K8_X125 under the hood. Incorrect settings may be set in the vehicle menu. Try to remove the ECO economy mode, change the climate control and air conditioning settings.
At negative temperatures, the air conditioner will not turn on due to the low gas pressure in the system, therefore it is better to turn it on in winter. warm boxes(for lubricating seals). Check pressure, prime if necessary and check system for leaks. Check the operation of the clutch and compressor, the serviceability of the A / C button. The exact cause will be determined by the diagnostics in the service using a device connected to the diagnostic connector.
5 (7.5 A) - airbags.
6,7,8,9,10 - not used.

If the heating stops working side mirror, check the wiring between the body and the door and in the mirror itself. To do this, remove the cover or the entire mirror and check the contacts in the connector inside it.
Often the bottom contacts are burned or oxidized. If the heated mirrors do not work in conjunction with the heated rear window, also check fuse 11. Photo of the wiring and mechanism inside the mirror with the trim removed:
22 (20 A) - glass sliding roof (electric sunroof)... See also prev. 34.
23 (25 A) - rear door power windows... If one of the glasses in back doors has stopped going down / up, check the wiring harness that comes out of the body and enters the door. Usually a brown wire breaks there, which goes to ground.
Also check the serviceability of the button on the door, the motor and the lift mechanism by removing the door trim. It does not hurt to check the fuse 1, which is responsible for the operation of the front power windows.
24 (7.5 A) - diagnostic connector... The OBD2 connector is located under the handbrake, hidden behind the shelf trim. To diagnose errors, Tech2, MDI or OP-COM scanners are usually connected.

2 (30 A) - anti-lock brakes ABS... If the ABS lamp on the panel lights up and the system stops working, check and clean the ABS sensors and speed sensors at the front and rear wheels, their wiring and connectors. The case may also be in the ABS control unit. A more accurate reason can be said by the result of the device diagnostics.
Usually, problems with ABS arise after replacing the wheel hubs or their bearings, when assembling the units, the sensors or their connectors are incorrectly installed, which leads to chafing of the wires or lack of contact.
3 (30 A) - stove fan (climate control).
4 (30 A) - stove fan (air conditioner)... If the stove stops working, it is possible that the fan itself is clogged, its motor or thermal fuse has burned out. Clogging is especially likely if the stove has not been serviced for a long time (several years). Disassemble the stove, clean all components and lubricate the fan axle and bearings.
To get to the stove, you need to remove the glove compartment. If the stove works only in the last maximum position, you need to change the resistor. The case may also be in the climate control or air conditioning control unit. If the stove is blowing cold air, check the level of antifreeze and the presence of air in the cooling system.
5 (30 or 40 A) - radiator fan.
6 (20, 30 or 40 A) - radiator fan motor... If the cooling fan stops turning on, check the health of its engine by applying voltage from the battery directly. If the engine does not work, remove it, disassemble and clean it by checking the brushes or replace it with a new one. It could be an electronic control unit, temperature sensor, thermostat, or wiring. Correct diagnosis will show the exact cause.
7 (10 A) - front and rear washers... If the washer stops working during a cold snap, check the fluid level in the washer reservoir, whether it is frozen in the pipes and nozzles. Warm up if necessary and change. Also check the serviceability of the pump-pump in the tank by applying a voltage of 12 V and wiring to it.
8 (15 A) - sound signal... If the signal stops working, most likely the matter is in the CIM module, the steering column cable and its connector. In this case, the buttons located on the steering wheel (for example, volume) usually stop working. A common problem. If the matter is in the SIM module, soldering the contacts on its board, repairing broken wires or replacing it with a new module usually helps.
9 (25 A) - front and rear washers... See above before. 7.
10, 11, 12 - not used.
13 (15 A) - fog lights... If not working, check bulbs, connectors and wiring.

23 (10 A) - headlights, adaptive light (AFL system), tilt angle corrector... If the low beam or high beam stops working, check and replace the bulbs. To replace a lamp in one of the headlights, you need to turn the wheels in the opposite direction, open a special hatch located in the wheel arch, remove the rubber boot from the headlight through it, remove the old lamp by turning it counterclockwise and install a new lamp, turning it to fix it in connector clockwise.
To turn on the "road home" headlights mode, you need to turn off the ignition and remove the key from the lock, open the driver's door and blink high beam(short pressing of the lever towards yourself). After that, when the driver's door is closed, the low beam + lamp will be turned on reverse that will automatically go out after 30 seconds.
24 (15 A) - fuel pump... If the pump does not pump gasoline and the engine does not start, check the wires under the hood in the corrugation between the engine control unit and the fuse box. Usually they are frayed there or the contact in the connectors for connecting to these blocks disappears. Diagnostics and error reading can determine the exact cause.
25 (15 A) - electronic gearbox systems.
26 (10 A) - electronic engine systems.
27 (5 A) - electric power steering... If the steering wheel starts to spin tight, check the power fuse FB3, the oil level in the power steering tank. The reservoir is located under the hood on the passenger side, in a recess near the windshield.
If the steering wheel turns tight only in cold weather, it works normally during warming, most likely the oil in the power steering system freezes, change the oil to one that is more resistant to temperatures. In case of problems with oil, it may fail or jam steering rack... The pump could also fail, in this case either repair or replacement with a new one.
