On Opel Astra N cars, fuse boxes play a very important role in protecting vehicle from fire due to a sharp increase in voltage. Therefore, some information about their location, functioning and device will be very useful to the car enthusiast.

Fuse box "Opel Astra N": purpose and device

The electrical equipment of the car plays a rather important role in the functioning of the entire vehicle. The operation of the headlights, ignition system, instrument panel illumination, car cigarette lighter and radio tape recorder depends on the health of the car's electrical wiring.

As noted earlier, the fuse box is designed to protect the vehicle from fire if the voltage rises rapidly. The fuses take the blow and are disposable. must be replaced immediately. Fuse boxes can be installed in the passenger compartment or under the hood of the vehicle.

It should be understood that each car manufacturer installs fuse blocks individually: on the Opel Astra N model, for example, they are located under the hood and in the passenger compartment (next to car cigarette lighter). However, this element can be installed in absolutely any part of the car: trunk, hood or interior. Trucks have about four to five fuse boxes.

On each car, the location of the safety blocks is individual: in order to find the safety blocks on a particular car model, you must refer to the operational documentation of the vehicle.

The fuse box "Opel Astra N" consists of a variety of relays and fuses directly. Each element is responsible for protecting one or another component of the vehicle.

On many models of the Opel Astra N car, two safety blocks are usually installed: one under the hood (on the driver's side), the other is located in luggage compartment and is located under the cover of the outer trim, also on the driver's side. The arrangement of the block components, as well as the diagrams, differs depending on the vehicle equipment. This arrangement is typical for the 2011 and 2010 Opel Astra N fuse boxes.

Therefore, for owners of these car models, the process of replacing parts will be approximately the same. After all, the 2010 Opel Astra N fuse boxes went unchanged into newest model auto.

Preparing to "tamper" with the safety block

Before starting the search for the fuse box, it is necessary to plug the power unit and turn off the ignition by turning the key to the OFF position. This must be done to prevent electric shock or short circuit of the 2008, 2010, 2011, 2007, 2006 Opel Astra N fuse box. Well, avoiding these consequences will save the vehicle from fire.

Since there is a risk of closing the contacts with a screwdriver when disassembling the fuse box, safety precautions must be strictly followed. Also, you should not deal with disassembling the part if you did not have experience with such car breakdowns before. It is cheaper and easier to bring a car to a specialist for a complete and thorough inspection.

How do I open the fuse box?

It is convenient to open the cover with a screwdriver. On the left side there are two clamps. The process of opening the cover of the 2007 Opel Astra N fuse box and cars of other years of production is as follows:

• the screwdriver is inserted into the slot between the clip and the cover;
• the clamp is slightly bent, then the cover should be lifted;
• a similar operation is carried out with the second clamp;
• the cover is placed vertically.

If you do all these operations, you will be able to remove the cover without any problems, it will only have to be pulled up slightly.

The 2006 Opel Astra N fuse box consists of two parts. Therefore, the disassembly process looks slightly different. The cover is removed from the block for mounting relays and fuses. To dismantle it, press on the inner clamps. After that, in the same way (pulling up), the cover is removed, thereby opening access to the main fuses, which are placed in a row.

It is worth noting that the 2007 Opel Astra N fuse box also consists of two parts. Moreover, this car model is the last on which a similar part was installed. The fuse box "Opel Astra N" 2008 and subsequent years of production - one-piece, not divided into parts.

Fuse box decoding

After the cover has been dismantled, the "bonnet" fuse box "Opel Astra N" 2008 and other years of production, on which an integral part is installed, opens. An open fuse box is an ordered arrangement of fuses and relays. Each element is able to withstand a certain amount of electricity, and is also responsible for the car's devices.

For ease of identification, each fuse has its own color, depending on what amperage it can handle. Based on this, the pinout of the Opel Astra N fuse box is formed.

Layout diagram of relays and fuses in different models auto with various configurations will be different. Therefore, before the intervention, you need to make sure that the existing circuit fits your Opel Astra N car.

"Distribution" of relays and fuses: the first type of equipment

The fuse box, installed on the "Opel Astra N", when basic configuration the car protects a number of important elements from failure as a result of a sudden power surge.

Anti-lock braking system fuses are capable of withstanding 20 to 30 amperes; climate control, as well as the system responsible for heating and ventilation of the car's interior space, withstand about 30 amperes. The cooling fan is protected by a fuse capable of withstanding 30 to 40 amperes. The central locking can handle 20 amperes.

It is worth noting that the above list does not fully reflect all vehicle systems that are protected by fuses. To find out full list, it is necessary to carefully study the technical documentation of the car.

Rear fuse box "Opel Astra N"

As mentioned earlier, in the "Opel Astra N" there are two safety blocks: in front, in engine compartment car, and in the trunk. There are some designations on the fuses and relay of the trunk that require decoding:

• Heating rear window- KZ X131.
• Terminal 15a - K2 X131.
• Terminal 15 - K1 X131.

A complete decoding of the fuse box "Opel Astra N" is in technical documentation vehicle.

Trunk fuse box

The fuse box in the trunk of the "Opel Astra N" is located on its left side. In a car with a hatchback body type, you can get to the block by performing the following steps: the fixing elements of a round shape are unscrewed, after which the trim cover is lowered. The sedan also has a small cover equipped with two handles. You need to pull on them, disconnect the clips, and lift the cover up.

As with the bonnet safety block, a fully equipped vehicle is equipped with the largest and most complex safety block available.

How to diagnose fuse performance?

Often in the car, problems begin with electrical equipment, as well as with the ignition. One of the reasons for the malfunctions that have occurred is the failure of the fuses. However, before you climb into the safety block and check the fuses for the fact of operation, you need to check other possible malfunctions: The problem may be a dead battery or a burnt out light bulb.

Currently, fuses with a transparent body are used. Thanks to him, you can immediately determine whether a work item or not. If the fusible part of the fuse is melted, then such a device must be replaced immediately. However, on some fuses, this is quite difficult to see, therefore, you should also use a device that will allow you to accurately determine whether the fuse has failed or not.

When checking the performance of fuses, it is necessary to follow a certain algorithm, which will significantly save time and effort:

1. Visual inspection of the fuse.
2. Using a tester and indicator to determine if the fuse is working.
3. If the indicator light goes off and a short circuit is indicated, the fuse must be replaced: it is serviceable.
4. If nothing happened during the check, then the fuse must be replaced.

Checking by the indicator and tester is also carried out in a certain sequence:

• Pull the fuse out of the socket and clean its contacts.
• Study the instructions of the indicator and tester before testing, in accordance with the instructions, connect the fuse contacts. When an indicator appears indicating a short circuit, it can be concluded that the fuse is working. When checking the operating fuse, the indicator on the device should light up the lamp.
• Install a new fuse in place of the blown one. The main condition for replacement is that the characteristics of the new fuse must comply with the manufacturer's recommendations.

If there is no special device at hand, then you can always drive the car for an unscheduled inspection. Experts will be able to say with confidence whether replacement of old fuses is really necessary.

What if the problem is not with the fuses?

If the checks have shown that the fuses are operational, and the performance of the automotive systems has not been restored, then a complete diagnosis of the vehicle should be carried out at a specialized service center.

Independent intervention in other systems of the car can lead to the occurrence of serious enough breakdowns: it is then that a serious overhaul... Many motorists, wanting to save money on service inspection and maintenance, independently trying to figure out the breakdown of a car, only waste a huge amount of time, and also face huge monetary costs.

Precautions When Replacing Fuses

When you have everything you need to independently find out the cause of the car malfunction, you need to be extremely careful when interfering with the fuse box. After all, their replacement implies the observance of a number of precautions:

1. Before opening the cover of the safety block, turn off the engine and turn off the ignition.
2. All operations should be carried out carefully.
3. The fuses are removed carefully.
4. No need to rely only on visual inspection fuse, it must also be checked with instruments.
5. Before engaging in self-diagnosis and replacing fuses, you should carefully study the information about which fuse is responsible for what.
6. The new fuse must comply with the requirements and recommendations. car manufacturer which are presented to technical parameters devices.

The above precautions will allow not only to "bloodlessly" repair the car and replace defective fuses, but also to protect the repairman from electric shock, and the car from fire. Ignoring the above recommendations can cause a fire in the vehicle's wiring, as well as quite serious damage from electricity.

In this case, you should not ignore and postpone replacing blown fuses. If you drive with faulty fuses, then at the next power surge there is a high risk that the car's systems, which are left without protection, will fail. And replacing them is much more expensive than replacing fuses.

Conclusion

Summing up the above, it is worth noting that replacing the fuses is quite an important operation. Indeed, the performance of all vehicle systems that are "powered" by electricity depends on their performance.

The main reason for fuse failure is a sharp increase in the voltage of the electric current. The fuse is blown. Fuses are "consumables", they cannot be repaired, they are replaced.

It is possible to visually diagnose a breakdown of a fuse by a fusible element: if it is melted, then it should be replaced. But visual inspection is best confirmed using a tester and indicator. Some fuse models simply cannot be diagnosed by visual inspection alone.

Replacement of fuses is carried out only when it is known for which system each fuse is responsible. This information is found in the technical documentation for the vehicle.

Fuses must be replaced with precautions. Failure to heed them could result in a fire in the vehicle or severe electric shock.

Do not overstretch replacing a blown fuse. The next sudden increase in voltage can lead to a short circuit and fire the vehicle. The cost of fuses is not particularly high, therefore you should not save on this small, but rather important part in electrical system vehicle.

To gain access located in the engine compartment, squeeze the two latches and remove the cover. To access the fuses and relays located in the luggage compartment, turn the two cover latches 90º and fold it down.

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 window lifters 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 the panel illumination do not work, also check the 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, 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.
• 11 (25 A) - rear window heating.

If the rear window stops fogging or the heating turns on for only 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 to this, prev. 15 in the engine compartment. A common problem is moisture ingress into the engine and rear wiper mechanisms.

Rust can cause some parts to 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 on it. If the shaft is clogged, rusted, or does not turn, knock it out, clean it and reinstall it.

• 13 (5 A) - parking assistance system.
• 14 (7.5 A) - air conditioning system. See prev. 4.

• 21 (7.5 A) - heating of side mirrors.

It usually turns on when you press the rear window heating button. 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.

Wiring and connectors inside the rearview mirror in the Opel Astra H

Decoding:

• 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 up / down, check the wiring harness that goes 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 itself 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.

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 devices into it, make sure that there are no foreign washers on them that can fly off and close the contacts. It is better to connect the devices to an additional 12 V socket (if available) or to a splitter.
• 30 (15 A) - rear 12V socket.
• 31, 32 - not used.
• 33 (15 A) - Open & Start system.

• 37 - not used.
• 38 (25 A) - central locking, terminal "30".

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 is out of order and the unit “thinks” that one of the doors is open. This usually generates 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 you connect the device to the diagnostic connector.

• 39 (15 A) - heated driver's seat.
• 40 (15 A) - heated front passenger seat.

If the seats stop warming up when this feature is turned on, check the connectors and wires underneath.

Fuses in the box under the hood

Decoding:

• 1 (20 A) - anti-lock brakes ABS.
• 2 (30 A) - anti-lock brakes ABS.

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. The case may be in the ABS control unit. A more precise 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 unit or air conditioning. 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 has frozen in 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.
• 14 (30 A) - cleaners windshield... If the "wipers" do not work, most likely the mechanism in the gear motor or the wire contacts is clogged or frozen. Disassemble and clean. Also check the motor brushes.

Setting the interval of operation of the cleaners in intermittent mode: press the wipers' lever down to activate them, wait for the required time and turn on the intermittent mode of their operation (switch the lever up). The cleaners will now run at the specified 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) - heating fuel filter(only for diesel engines).
• 18 (25 A) - starter. If it does not twist, 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 solenoid relay and the wiring / connectors. If there is an automatic transmission, check its selector, the serviceability of the brake pedal switch. Diagnostics will indicate the exact cause.
• 19 (30 A) - electronic systems gearboxes.
• 20 (10 A) - air conditioning compressor. See prev. 4 in the luggage compartment.
• 21 (20 A) - electronic engine systems.
• 22 (7.5 A) - electronic engine systems.
• 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” headlamp operating mode, you need to turn off the ignition and remove the key from the lock, open the driver's door and blink the high beam (briefly pressing 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 systems of the gearbox.
• 26 (10 A) - electronic engine systems.
• 27 (5 A) - electric power steering.

If the steering wheel becomes tight, check power fuse FB3, power steering oil level. 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.

Free collection of fuse diagrams of all 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. Fuse holders are often provided for storing them in the fuse box in the engine compartment. You can clarify the wiring diagram in.

Fuses OPEL OMEGA B

Circuit breakers
The marking of the new fuse must match the marking of the defective fuse.

The car has three fuse boxes:
■ on the left front of the engine compartment.
■ behind the storage compartment in left-hand drive vehicles or, in right-hand drive vehicles, behind the glove compartment.
■ under the lid on the left side of the luggage compartment.

Before replacing a fuse, turn off the appropriate switch or switch off the ignition.

A defective fuse can be identified by a burnt-out fuse. Replace the fuse only after eliminating the cause of its failure.
Some circuits may be protected by multiple fuses.
In addition, fuses with no specific purpose can be inserted.

Fuse Remover
The fuse remover is stored in the engine compartment fuse box.

Slide the device onto the fuse from the top or from the side, depending on the type of fuse, and remove the fuse.

Engine compartment fuse box

The fuse box is located in the front left of the engine compartment.
Release the cover latch and lift the cover up until it stops. Remove the cover by pulling it straight up.

After replacing blown fuses, close the fuse box cover and fix it by pressing from above. If the fuse box cover is not closed properly, a malfunction may occur.

Fuse box in dashboard

On left-hand drive vehicles, the fuse box is located behind the glove compartment on the dashboard. Open the compartment and push to the left to unlock. Pull the compartment down and remove it.

On right-hand drive vehicles, the fuse box is located behind a cover in the glove compartment. Open front glove box, then open the cover and lower it down.
