On Opel Astra N cars, fuse blocks play a very important role in protecting the vehicle from fire due to a sharp increase in voltage. Therefore, some information about their location, functioning and device will be very useful for a 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 depends on the he alth of the car's electrical wiring.

As noted earlier, the fuse box is designed to protect the car from fire when the voltage rises sharply. Fuses take a hit and are disposable. A blown fuse must be replaced immediately. Fuse boxes caninstalled in the cabin 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 cabin (next to the 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.

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

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

On many models of the Opel Astra N, two safety blocks are usually installed: one under the hood (on the driver's side), the other is located in the luggage compartment and is located under the cover of the outer skin, also on the driver's side. The location of the components of the blocks, as well as the diagram, differs depending on the vehicle configuration. This arrangement is typical for the fuse box "Opel Astra N" 2011 and 2010 release.

Therefore, for the owners of these car models, the process of replacing parts will be approximately the same. After all, the 2010 Opel Astra N fuse blocks were transferred tolatest car model.

Preparing to "intervention" in the safety block

Before you start searching for the fuse box, you must turn off 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 shorting of the Opel Astra N fuse box 2008, 2010, 2011, 2007, 2006. 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 observed. Also, do not engage in disassembly of the part, if before that there was no experience with similar car breakdowns. Cheaper and easier to drive a car to specialists for a complete and thorough inspection.

How to open the fuse box?

Opening the lid is convenient with a screwdriver. On the left side there are clips in the amount of two pieces. The process of opening the cover of the fuse box "Opel Astra N" in 2007 and cars of other years of manufacture is as follows:

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

If you do all these operations, you can easily remove the cover, it remains only to slightly pull up.

Blockfuse "Opel Astra N" 2006 release 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 internal clamps. After that, the cover is removed in a similar way (pulling up), thereby opening access to the main fuses, which are placed in a row.

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

Deciphering the fuse box

After the cover has been dismantled, the "bonnet" fuse box of the "Opel Astra N" 2008 and other years of production, on which an integral part is installed, opens up. 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 devices of the car.

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

Color	Voltage
Purple	3A
Brown	7, 5 A
Beige	5 A
Blue	15 A
Red	10 A
Yellow	20 A
Green A	30 A
Pink	30 A
Green B	40 A
Transparent	25 A

The arrangement of relays and fuses in different car models with different trim levels will be different. Therefore, before intervening, you need to make sure that the existing scheme fits your Opel Astra N car.

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

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

Anti-Lock Brake System fuses can handle 20 to 30 amps; climate control, as well as the system responsible for heating and ventilating the passenger compartment of the car, can withstand about 30 amperes. The fan operating in the complex of parts of the cooling system is protected by a fuse that can withstand from 30 to 40 amperes. The central lock can withstand 20 amps.

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

Rear fuse box "Opel Astra N"

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

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

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

Fuse box in trunk

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 following these steps: the round-shaped fixing elements are unscrewed, then the casing 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 fuse box, the fully equipped car has the largest and most complex fuse box.

How to diagnose he althfuses?

Often in the car, problems begin with electrical equipment, as well as with ignition. One of the causes of the malfunctions is the failure of the fuses. However, before getting into the fuse block and checking the fuses for the fact of operability, it is necessary to check other possible malfunctions: perhaps the problem is a dead battery or a burnt out light bulb.

Fuses with a transparent body are currently used. Thanks to him, you can immediately determine whether the 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, so 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 that will significantly save time and effort:

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

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

• Remove the fuse from its socket and clean its contacts.
• Exploreindicator and tester instructions before checking, in accordance with the instructions, connect the fuse contacts. When an indicator appears indicating a short circuit, we can conclude that the fuse is working. When checking the working fuse with the indicator on the device, the light should light up.
• Install a new fuse in place of the burnt one. The main condition for replacement is the fact that the characteristics of the new fuse must comply with the recommendations of the car manufacturer.

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

What if the problem is not the fuses?

If the checks showed 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 car systems can lead to quite serious breakdowns: it is then that a serious overhaul will be needed. Many motorists, wanting to save on service inspection and maintenance, trying to figure out a car breakdown on their own, only lose a huge amount of time, and also face huge cash costs.

Fuse replacement precautions

When there is everything you need forin order to independently find out the cause of the malfunction of the car, you need to be extremely careful when intervening in the fuse box. After all, replacing them involves observing a number of precautions:

1. Turn off the engine and turn off the ignition before opening the safety box cover.
2. All operations should be carried out carefully.
3. Fuses are removed carefully.
4. Don't just rely on a visual inspection of the fuse, it should also be checked with instruments.
5. Before you engage in self-diagnosis and replacement of fuses, you should carefully study the information about which fuse is responsible for what.
6. A new fuse must comply with the requirements and recommendations of the car manufacturer, which apply to the technical parameters of the device.

The above precautions will allow not only to “bloodlessly” repair the car and replace failed fuses, but also protect the repairer 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.

At the same time, do not disregard and postpone the replacement of blown fuses. If you drive with faulty fuses, then at the next power surge there is a high risk that the car's systems that were left without protection will fail. And replacing them is much more expensive than replacingfuses.

Conclusion

Summarizing the above, it is worth noting that replacing fuses is a rather important operation. After all, the performance of all vehicle systems that are “powered” by electricity depends on their performance.

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

You can visually diagnose a broken fuse by the fusible element: if it is melted, then a replacement should be made. But visual inspection is best confirmed by using a tester and an indicator. Some fuse models simply cannot be diagnosed by visual inspection alone.

Fuses should only be replaced when it is known which system each fuse is responsible for. This information is in the technical documentation for the vehicle.

Fuses are replaced with care. Failure to do so may result in a fire in the vehicle or severe electric shock.

Don't delay replacing a blown fuse. The next sudden increase in voltage can cause a short circuit and fire the vehicle. The cost of fuses is not particularly high, so you should not save on this small, but quite important part in the electrical system of the vehicle.
