The fuse block is a node where all the safety elements of the power grid are focused. They are used to protect electrical equipment from voltage jumps, so their performance is very important for any car. You will learn more about the replacement and location of the items from this material.

Installation block of fuses VAZ 2107, where and why it is needed

The main part of the used fuses is mounted in the main device located under the hood. The shield is located under the windshield, opposite the passenger chair. Domestic 2107, whether it is an injector or carburetor, can be equipped with two types of devices - a new and old sample. Accordingly, the scheme and description of electrical equipment in them is insignificant. The devices of the old sample were used on cars of early release, and new ones in later versions.

If you speak directly about the carburetor and the injector, the type of fuel supply system does not affect the power supply of devices. Both injection and carburetor versions of cars can be equipped with old and new blocks. In versions of the car, which were released later, the fuse unit can be mounted in the TC cabin under the glove compartment.

Decryption of the fuses of the VAZ 2107 of the old sample

1. This element is designed to protect the electrical electrical storage headload, the stove engine, the lamp on the instrument panel, as well as the rear window warming relay.
2. It is needed to protect the engine wizard brushes, the windows and optics cleaning system, if such is provided by the manufacturer.
3. The auxiliary connector is applied when adding new devices.
4. The auxiliary connector is applied when adding new devices.
5. The operation of the heating system of the rear window.
6. Provides the work of the cigarette lighter. Sometimes responsible for the radio, depending on the car.
7. The device is used to ensure uninterrupted functioning of the Classone and the ventilating device motor, which cools the radiator.
8. Emergency light alarm.
9. Uninterrupted work of fog optics. Sometimes it is responsible for functioning the voltage regulator of the generator.
10. The component is responsible for the operation of a combination of devices, ankb charge indicator, turning pointers, manual brakes, oil pressure, fuel reserve, fuel levels.
11. Stop lights. Pluphones internal body light.
12. Far headlight, right, activation of optics cleaning relay.
13. Far light, left, long-mounted activation lamp.

18. Protection of electrocups headlight headlights.
19. Protection of the chain of high-light lamps.
20. Sound signal performance.
21. Provides functioning of optics cleaning systems, if the car is equipped with a washer.
22. Functioning of the rear window warming system.

Fuses VAZ 2107 Injector, installation location

It is worth noting that the injection vehicles are equipped with an additional relay block, which is located in the cabin under the clothing box.

Decoding Fuses VAZ 2107 Injector

• R1 is the main relay.
• F1 - Provides the functionality of the main relay.
• F2 - protects the electronic unit from voltage jumps.
• F3 - protects the chain of the fuel pump. When the engine is output, the engine does not start.
• R2- ensures the performance of the fuel pump.
• R3 - Protects the radiator fan.

Tools, fixtures, consumables

To replace the fuses, you will need tweezers, which is usually present under the lid of the device. If it is not, use the passage.

Safety in the work under voltage

Be sure to turn off the ignition and disconnect the terminals from the battery.

How to replace VAZ 2107 fuses in the mounting unit

Replacement procedure:

1. Find a device mounting place. There are fixators on the plastic lining of the block. Click on them.
2. After removing the lining, you will see the scheme applied to the opposite direction. Here is the purpose and location of all components used here.
   
3. Next, detect which device broke and shall be replaced. Sometimes you can determine the breakdown visually - the element itself can be blown, and sometimes a torn thread is visible in it.
4. Tweezers remove the burned component and change it to a new one. Then we install the lid and connect the battery terminals.

How to replace the fuse VAZ 2107 in the car

When the fog-optics exit, it is necessary to diagnose the device operation. The element is located in the cabin of the car. For diagnostics and replacement, we carry out such actions:

1. First you need a cross screwdriver, use it to dismantle two switches that are located in the center of the console, in the area of \u200b\u200binstallation of the audio system.
   
2. Using a screwdriver, press the two mounts.
3. Remove the plastic insert.
   
4. Remove the fuse housing. Remove the device's protective cover and replace the element to the new one.
   

How to replace VAZ 2107 fuse block

Order of work:

1. Open the motor compartment and dismantle the airflow case. Remove the nuts fixing the housing.
2. Under the device you will see a plug with cables connected to the device. Disconnect it. On the body of the product there is a marking corresponding to the color of the connected connectors. Thus, you can avoid the need to marking cables.
   
3. Then climb into the salon and remove the shelf located under the control panel. Then unscrew the bolts that keep the bardaches body.
   
4. Next, turn off the plug with cables that are connected to the device connectors. After that you will see color marking.
   
5. Spanning key unscrewing bolts that fastening the block. The most extreme screw located on the housing is hidden, so you can not immediately see it.
   
6. Remove the unit with devices and replace the device. Installation and assembly of components are performed in reverse order.
   

How to check and replace the VAZ 2107 relay

This component is in the mounting block. The exact place of installation can be obtained from the scheme applied to the opposite side of the protective overlay:

1. Turn off the ignition and open the fuse block.
2. We find a relay to check and replace.
3. We dismantle it with forceps that are in the block of the block.
4. Install another device instead of extracted. You can use the relay from the reflection system of the headlight or head light.
5. If the check showed that the dismantled relay does not work, install a new one in its place.

The procedure for checking and replacing is similar to all devices. The difference is only in their location:

1. Basic relays are in a block with fuses.
2. The starter activation relay is under the hood, on the right mudguard.
3. A device that ensures the operation of turning, ignition and light alarm, is located in the cabin of the car, behind the instrumental combination.
4. The windows cleaning device is located on the driver side under a combination of instruments, it is attached to the body with two bolts.
