Free collection of fuse diagrams for all Opel models. Opel cars have a lot of electrical circuits that are protected by fuses, thanks to which you can successfully avoid unpleasant, and sometimes even dangerous situations. It will be unacceptable to simply close the burned-out fuse-links with "bugs" made of thick wire. But even a serviceable fuse can bring surprises - due to loose fuse holders or oxidized fuse tips, the contact part “burns”, resulting in an increase in contact resistance and, as a rule, heating, then the contact deteriorates even more, problems arise with the operation of the car’s electrics . We recommend that they be inspected and cleaned at least once a year. It is recommended to keep several spare fuses in the machine at all times. For storage in the fuse box located in the engine compartment, appropriate holders are often provided. You can clarify the electrical equipment diagram in.

Opel Astra N. Location of fuses, fuses and relays and their replacement
Most vehicle electrical power circuits are protected by fuses. Headlights, fan motors, fuel pump and other powerful current consumers are connected via relays. Fuses and relays are installed in mounting blocks, which are located in the trunk of the car under the sidewall lining on the left side and in the engine compartment next to the battery.
The designations of the fuses and relays of the mounting block installed in the trunk under the lining of the left sidewall are shown in fig. 10.1.
In table. 10.1 indicates the purpose of these fuses, fuses and relays, but on a particular car model, some of the circuits indicated in the table may not be available.
The designations of the fuses and relays of the mounting block installed in the engine compartment on the right in the direction of travel are shown in fig. 10.2.
In table. 10.2 indicates the purpose of these fuses, fuses and relays, but on a particular car model, some of the circuits indicated in the table may not be available.
1. To gain access to the fuse mounting block located in the trunk, turn 90 ° two hatch cover latches in the left side trim ...
2….and flip down the cover.
3. To gain access to the mounting block located in the engine compartment, press the two latches with a screwdriver ...
4….and remove its cover.
Note.
Spare fuses B and tweezers A are fixed in special sockets of the body of the mounting block located in the trunk to remove the fuses from the mounting blocks.
5. Before replacing a blown fuse or fuse, find out the cause of the blown and fix it. When looking for a malfunction, look at the ones listed in Table. 10.1 and 10.2 circuits that this fuse or fuse protects.
Warning.
Do not replace fuses with fuses of a different amperage or homemade jumpers, as this may damage electrical appliances and even cause a fire.
6. Remove the tweezers from the base of the mounting block located in the trunk.
7. Grab the fuse with tweezers ...
8….and remove it from the connector.
Note.
This is how a blown fuse looks like (the jumper shown by the arrow inside the holder has blown and opened). To replace a fuse, use a spare fuse of the same rating (and color).
9. Install a fuse of the same rating as the removed one into the connector.
10. If replacement is necessary, remove the relay from the mounting block by rocking it from side to side ...
11….and install a new relay.
For some reason, the cigarette lighter fuse burnout on the Opel Astra H is a frequent occurrence. We have prepared a step by step guide on how to replace it.
Step 1. We are looking for a hatch in the trunk
First you need to find the fuse box hatch in the trunk. It usually looks like this:
The fuse box in the Opel Astra H sedan usually looks like this:
If your hatch looks different from the one shown in the picture, then you have a rare equipment, this happens, it's okay, no need to panic.
Step 2. Determine the type of fuse box
Now we need to understand which fuse box your Astra is equipped with. The fact is that most of the cars of this brand were equipped with a “full mounting block”, but some cars, especially the basic configuration, were equipped with a “simple mounting block”. A simple mounting block is much smaller and very rare. But everything happens.
This is what the “complete mounting block” of fuses looks like: 
This is what a “simple mounting block” of fuses looks like: 
Step 3: Replacing the cigarette lighter fuse
If you have a simple mounting block (this happens VERY RARE), then you can safely close the trunk, there is no fuse you need in it. Open the hood and change the FЕ36 fuse, rated 7.5A (if the cigarette lighter backlight is covered, you can also change it - FЕ33, 5A). But, as we wrote above, this is a rarity.
If you have a traditional full mounting block in the trunk, then you need to change the FR29 fuse, rated 15A (FR18, 5A - backlight): 
What to do if the cigarette lighter is stuck?
Most often this is due to a blown fuse. Just replace it and the fuse will blow back.
What should I do if the charger plug does not stay in the cigarette lighter and falls out?
Instead of changing the whole cigarette lighter, buy a 2-way splitter and plug it into the cigarette lighter.
What is the breakdown if the fuse blows immediately after turning on the device (for example, a navigator) in the cigarette lighter?
Try plugging the cigarette lighter into the cigarette lighter socket and see what happens. If the fuse blows again, then the problem is in the car's electrical circuit, if the fuse does not blow, then the problem is in the connected device.
After replacing the cigarette lighter fuse, the central locking stopped working, what should I do?
We have already written a separate one with a detailed manual on what to do in this case.
What should I do if the wheel pump is too powerful and blows the fuse?
Instead of buying a new pump, it's better to cut off the cigarette lighter plug and solder a couple of crocodiles for the battery. Connect the pump directly to the battery.
Which inverter is suitable for Opel Astra H?
Choose an inverter with a maximum power of 120 watts. If you buy a more powerful one, the fuses will fly out.
Where is the socket in the trunk of the Opel Astra H?
The socket in the trunk is located on the right wall of the trunk, but not all trim levels have it. Those who have it are lucky - you can connect a vacuum cleaner to it while cleaning the trunk or a car refrigerator on long trips. 
The fuse box in a car is an important element in ensuring the good condition of all electrical mechanisms. Each fuse on the Opel Astra G is responsible for a specific section of the electrical circuit. The burnout of this part is a signal of a malfunction or improper operation of the machine components.
[ Hide ]
Location and wiring diagram
Circuit breakers car Opel Astra G are located in separate mounting blocks of the electrical system, which are installed in the instrument panel and engine compartment. The last block contains fusible links and relay mechanisms for the electrical circuits most loaded in terms of current strength. This position of the safety elements allows you to ensure the reliable operation of the car's electrics. Both blocks in cars before 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.
Scheme of installation of elements in the cabin block
On Astra cars manufactured in 1998, 1999 and 2000, on the left side of the block located under the hood, there are sockets F1-F5 for more powerful fuses. To the right - two rows of vertically installed fuse-links marked F6-F23 and F24-F41. Above the fuse sockets there are regular places for spare parts and plastic pliers, which are used when replacing parts. In the same block there are eight more fuse-links, which are the same for all Opel Astra G cars and arranged vertically in a row.
Fuses and relays are installed in the mounting block located in the cabin. The fuses are rated from 7.5 to 40 amps and are located in two rows at the bottom of the block.
Layout of the relay in the early block The wiring diagram of the early version of the cabin unit, the fuse locations are circled in red, the places for spare inserts and plastic tongs are circled in green Block of machines from 2001 with fuse designation Wiring diagram of the relay in the late unit
Fuse decoding
A complete description of the Opel Astra G fuses 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 fuses 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 circuits;
- 2 (60 A) - general protection of the fuse box in the cabin, engine control mechanism;
- 3 (60 A) - relay in the dashboard of the car;
- 4 (40 A) - protection of electric motors of the cooling and air conditioning system from short circuit;
- 5 (60 A) - ABS block;
- 6 (30 A) - circuits of engine control units (gasoline pump, injection system, ignition, etc.);
- 7 (80 A) - power steering;
- 8 (40 A) - protection of electric motors of the cooling and air conditioning system from short circuit (only on machines with air conditioning).
Relay type and purpose
The decoding of the relay of the early sample mounting block is as follows:
- 1 - encoding connector;
- 2 - horn relay;
- 3 - switching on the high beam;
- 4 - rear wiper activation relay;
- 5 - heated mirrors;
- 6 - turn 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 rear window heating.
The turn signal relay can be made in a common housing or in separate parts.
The video from kivalssl1 shows the installation of the "comfort" block relay in the Astra G mounting block.
On models 2001, 2002, 2003, 2004 and the following years of release, the purpose of the relay has slightly changed. Relay 11 was added, which is responsible for transmitting signals from wheel rotation sensors and relay 13 for interior lighting. On the side, a “comfort” device is inserted into the mounting block, indicated in the diagram by the number 15.
Below is the designation of several more relays in the engine compartment block.
How to replace 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
A guide to replacing failed fuses, for example, those responsible for the operation of the stove or cigarette lighter, is as follows:
- Turn off the vehicle's ignition system.
- Open a small folding box on the instrument panel, located in the area of \u200b\u200bthe knee of the driver's left leg.
- Press the plastic clips located 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. To do this, the damaged fusible element must be removed from the socket. There are small plastic tongs included with the mounting block. They need to clamp the fuse case, pull it out of the seat and insert a new part.
- Visually check the condition of the remaining fuse links.
- Perform reassembly.
It is important to note that the new fuse must have the same rating as the failed fuse. In the absence of such a detail, an element of a slightly larger value can be used. Only first you need to check the working condition of the circuit, for this you should install a fuse from any other socket with the required rating. If the fuse remains intact, then a part with a higher rating should be put in its place. But at the first opportunity, it should be replaced with a part with a regular rating. Since prolonged use of an incorrect fuse may damage the vehicle's electrical systems and cause a 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 for changing fuses on a more modern 2008 Opel Astra H or 2012 Opel GTC is identical to the above.
Replacing parts in the engine compartment is even easier. To do this, unfasten the plastic covers of the blocks and change the damaged fuses or relays.

Block replacement
During the operation of the car, situations may arise in which the mounting blocks are severely damaged. In this case, the owners are forced to change the entire blocks, buying new parts or using those removed from other machines.
To perform such a replacement, you need experience with electrical systems, as well as various tools and devices, so this procedure is best done in a specialized workshop.
But in the case when it is decided to replace the block inside the cabin with your own hands, the sequence of actions will be as follows:
- De-energize the vehicle by disconnecting the battery. Before this, you need to make sure that the code for the standard audio system is saved.
- Get access to 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 that the colors of the cables match.
- Connect the power to the car 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.
This model has been in production 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 become 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 error diagnosis - all this may be needed to fix Astra.
In the basic and complete sets, the 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 there is a full-fledged one. Under the hood, the fuse numbering of the basic version does not match the full version. This is due to the difference in electronic components and different electrical circuits.
This article discusses the mounting blocks of a complete set.
Fuses in trunk:
1 (25 A) - power windows in the front doors. If the glass lift of one of the front doors suddenly stops working, first check this fuse, then the wiring at the door opening, between the body and the door.
The wire could break off or the contact connector oxidized. Remove the trim from the door and check the wires inside the door. Check ground (brown wire between body and door). With the casing removed, also inspect the lift drive mechanism and check its motor.
If the power windows 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 power window up 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 the backlight of the panel 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, also check 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 in the vehicle menu may be set. Try removing the ECO mode, changing 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, so in winter it is better to turn it on in warm boxes (for lubricating seals). Check the pressure, top up if necessary and check the system for leaks. Check the operation of the clutch and compressor, the serviceability of the A / C button. The exact cause will help to determine 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.
11 (25 A) - heated rear window. If the rear window stops fogging or the heating only turns on for a few seconds, also check fuse 18 in this block and relay K3_X131 in the block under the hood.
12 (15 A) - rear window cleaner. If the rear "wiper" does not work, check in addition, prev. 15 in the engine bay. A common problem is moisture getting into the motor and rear wiper mechanism. Due to the formation of rust, some parts may jam.
To remove the mechanism with the motor, you need to remove the tailgate trim, and then the mechanism itself. After removal, check the condition of the shaft by knocking out the sleeve that is put on it. If the shaft is clogged, rusted, or not spinning, knock it out, clean it, and reinstall it.
13 (5 A) - parking assistance system.
14 (7.5 A) - air conditioning system. See prev. 4.
15 - not used.
16 (5 A) - passenger detection system in the front seat, Open & Start system.
17 (5 A) - tire pressure sensor, rain sensor, air quality sensor, auto-dimming rear-view mirror.
18 (5 A) - devices and switches on the panel. See prev. 3.
19 - not used.
20 (10 A) - shock absorber control (CDC system).
21 (7.5 A) - heated side mirrors. It usually turns on when you press the rear window heating button. If the heating of the side mirror stops working, check the wiring between the body and the door, as well as in the mirror itself. To do this, remove the trim or the entire mirror and check the contacts in the connector inside it.
Often the lower contacts burn or oxidize. If the heated mirrors do not work together with the rear window heating, also check fuse 11. Photo of the wiring and mechanism inside the mirror with the trim removed:
22 (20 A) - glass sliding roof (motor sunroof). See also prev. 34.
23 (25 A) - power windows of the rear doors. If one of the windows in the rear doors has stopped going up/down, check the wiring harness that comes out of the body and goes into the door. Usually there is a broken brown wire that goes to ground.
Also check the serviceability of the button on the door itself, the motor and the lift mechanism by removing the door trim. It does not hurt to check 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 cover. To diagnose errors, Tech2, MDI or OP-COM scanners are usually connected.
25 - not used.
26 (7.5 A) - electric folding side mirrors.
27 (5 A) - alarm, ultrasound sensor. In the standard Opel Astra H alarm, to arm, you need to press the key fob button 2 times, after which the car will arm with a delay of 15 seconds. To simply close all the doors, you need to press the same button 1 time, then the security mode will not turn on. To open or close all windows, you need to press and hold the open / close button, respectively.
28 - not used.
29 (15 A) - cigarette lighter, 12 V socket on the center console. Usually this fuse blows when there is a short circuit in the cigarette lighter socket. If you insert non-standard connectors from appliances into it, make sure that there are no extraneous washers on them that can fly off and short out the contacts. Devices are best connected to an additional 12 V socket (if available) or to a splitter.
30 (15 A) - 12 V rear outlet.
31, 32 - not used.
33 (15 A) - Open & Start system.
34 (25 A) - glass sliding roof (electric sunroof). See also prev. 22.
35 (15 A) - 12 V rear outlet.
36 (20 A) - socket for connecting a trailer, towing device.
37 - not used.
38 (25 A) - central locking, terminal "30". For problems with the alarm, see 27. If the central locking stops closing the doors, check if the interior light is on. If it is on, most likely the limit switch in one of the doors has failed and the unit “thinks” that one of the doors is open. This usually triggers an alarm.
In case of problems with the central lock, you can try to throw off the battery terminal for a while and connect it back. To determine the exact cause, you can diagnose using the methods described at the end of the article or in a car service when connecting the device to the diagnostic connector.
39 (15 A) - heated driver's seat.
40 (15 A) - front passenger seat heating. If the seats stop heating when this feature is enabled, check the connectors and wires underneath.
41, 42, 43, 44 - not used.
Relay in trunk:
K1_X131 - ignition lock relay, output "15".
K2_X131 - ignition lock relay, output "15A".
K3_X131 - rear window heating relay. See prev. eleven.
Fuses in the box under the hood:
The engine compartment mounting block is located on the left driver's side, under the hood between the pillar support and the left headlight. To get to it, you need to open the lid by prying it around the edges.
1 (20 A) - ABS anti-lock brakes.
2 (30 A) - ABS anti-lock brakes. If the ABS lamp on the panel lights up and this system stops working, check and clean the ABS sensors and speed sensors at the front and rear wheels, their wiring and connectors. It could also be the ABS control unit. A more accurate reason can be said by the result of diagnostics by the device.
Usually, problems with ABS occur after replacing the wheel hubs or their bearings; when assembling the units, the sensors or their connectors are not installed correctly, 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, the fan itself may be clogged, its motor or thermal fuse has blown. 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 only works in the last maximum position, you need to change the resistor. It could also be the climate control unit or the air conditioner. If the stove blows 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 has stopped turning on, check the health of its engine by applying voltage from the battery directly. If the motor does not work, remove it, disassemble and clean, checking the brushes or replace with a new one. The case may be in the electronic control unit, temperature sensor, thermostat or wiring. Proper diagnosis will reveal the exact cause.
7 (10 A) - front and rear windshield washers. If the washer stops working when it gets cold, check the fluid level in the washer reservoir to see if it has frozen in the pipes and nozzles. Reheat if necessary and change. Also check the serviceability of the pump-pump in the tank by applying 12 V voltage and wiring to it.
8 (15 A) - sound signal. If the signal stopped working, most likely the matter is in the CIM module, steering column cable and its connector. In this case, the buttons located on the steering wheel (for example, the 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 windshield washers. See above prev. 7.
10, 11, 12 - not used.
13 (15 A) - fog lights. If not working, check bulbs, connectors and wiring.
14 (30 A) - windshield wipers. If the “wipers” do not work, the mechanism in the gear motor or the wire contacts is most likely clogged or frozen. Take it apart and clean it. Also check the motor brushes.
Setting the interval for the operation of the wipers in intermittent mode: press the “wipers” lever down to operate them, wait for the required time and turn on the intermittent operation of their operation (switch the lever up). The cleaners will now run at the set interval. Valid values are 2-15 seconds.
15 (30 A) - rear window cleaner. See prev. 12 in the trunk block.
16 (5 A) - Open & Start system, opening roof, ABS, brake light switch.
17 (25 A) - fuel filter heating (only for diesel engines).
18 (25 A) - starter. If it doesn’t turn, check the K1_X125 relay, the battery charge, the contacts of its terminals, the negative contact on the car body, the serviceability of the starter itself, the retractor relay and the wiring / connectors. If automatic transmission, check its selector, serviceability of the brake pedal switch. Diagnostics will indicate the exact cause.
19 (30 A) - electronic systems of the gearbox.
20 (10 A) - air conditioning compressor. See prev. 4 in the luggage block.
21 (20 A) - engine electronic systems.
22 (7.5 A) - engine electronic systems.
23 (10 A) - headlights, adaptive light (AFL system), electric tilt angle corrector. If the dipped beam or high beam stops working, check and replace the bulbs. To replace the 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 by turning it to fix it in connector clockwise.
To turn on the “road home” mode of the headlights, you need to turn off the ignition and remove the key from the lock, open the driver's door and blink the high beam (shortly pressing the lever towards yourself). After that, when the driver's door is closed, the dipped beam + reversing lamp will be turned on, which will automatically turn off 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 disappears in the connectors for connecting to these blocks. The exact cause can be determined by diagnostics and reading errors.
25 (15 A) - electronic systems of the gearbox.
26 (10 A) - engine electronic systems.
27 (5 A) - electric power steering. If the steering wheel began to turn hard, check the power fuse FB3, the oil level in the power steering reservoir. The tank is located under the hood on the passenger side, in a recess near the windshield.
If the steering wheel turns tightly only in the cold, it works normally when it warms up, most likely the oil in the power steering system freezes, replace the oil with a more temperature-resistant one. In case of problems with oil, the steering rack may fail or jam. The pump could also fail, in this case, either repair or replace with a new one.
28 (5 A) - electronic transmission systems.
29 (7.5 A) - electronic transmission systems.
30 (10 A) - engine electronic systems.
31 (10 A) - headlights, adaptive light (AFL system), electric tilt angle corrector. See prev. 23.
32 (5 A) - air conditioning, clutch pedal switch, malfunction lamp in the brake system.
33 (5 A) - outdoor lighting (control unit), headlights, adaptive light (AFL system), electric tilt angle corrector.
34 (7.5 A) - steering module (control unit).
35 (20 A) - information and entertainment system.
36 (7.5) - Twin Audio system, display, radio, mob. telephone.
