Fuse blocks installed on old and updated versions of VAZ 2109 cars serve to combine all electrical wiring.
The main task of the power supply is to prevent breakdowns of electrical equipment installed in the car.
Where are the fuses VAZ-2108 2109 21099
The relay and fuse block for the VAZ 2108-09-099 (carburetor, injector) is located under the hood, in the compartment in front of the windshield on the left side.

Scheme
The entire line of VAZ 2109 cars can be divided into two branches - those produced before 1998 and those produced after 1998.
Older cars are equipped with fuse blocks whose marking is 17.3722. This power supply consists of a housing and an engineering board. Wire contacts, fuses and relays are soldered to the board.
Newer versions of nines, the production of which began in 1998, here the power supply is marked 2114-3722010-60. Here we are already seeing fuses.
If we talk about fuse blocks, the factor of the fuel injection system used - carburetor or injector - plays absolutely no role. BP will differ only by the year of manufacture of the car. Therefore, the mounting blocks for the carburetor and injector are the same.
The required mounting block is also located the same everywhere - in the engine compartment opposite the driver's seat, almost under the windshield.
Location
Differences
Are there any differences between the old and new versions of the power supply? Of course. They are as follows:
- The parts of the mounting block are marked differently;
- The fuse ratings are different;
- The new power supply does not have a relay for the cooling system fan motor and a time relay for the rear window washer device.

Relay
| Relay number | Functions |
| 1 | Performance of the front optics cleaning elements |
| 2 | Rear window washer motor performance |
| 3 | Protection against breakage of turn signal and light signaling lamps |
| 4 | Protection against failure of the windshield wiper motor |
| 5 | Allows you to determine the performance of the lamp |
| 6 | Rear window defogger overvoltage protection |
| 8 | High beam lamps |
| 9 | Low beam lamps |
| 11 | Responsible for the operation of the engine cooling fan. If this relay fails, the risk of engine overheating increases. |
| 12 | Klaxon operation |
Dismantling and replacement
If one or another equipment fails, you must first check the condition of the fuse responsible for it.
In practice, removing and removing an unusable fuse or relay is not difficult. To do this you need:
- Raise the hood and disconnect the minus from the battery. Since you are working with the fuse box responsible for electrical equipment, the car should not be energized at this moment;
- Find the mounting block. It is located in the engine compartment opposite the driver's seat directly under the windshield. The top of the block is covered with a plastic cover. To remove it, simply press the latches on the sides;
- Remove the cover and look at the back side. There is an electrical diagram showing the location of one or another fuse or relay. Just find the element that is responsible for the failed equipment according to the tables above;
- Remove the fuse. All mounting blocks are equipped with special pliers. Manually removing fuses is not recommended. The relays are removed by gently rocking up and down;
- Replace the failed component.
Fuse failure is determined by the melted filament. These are fusible elements that melt and make contacts, preventing equipment from being damaged by excessive voltage.
That's it, all that remains is to replace the fuse block element, close the cover, replace the battery terminal and check the functionality of the equipment.

Very often, car owners are looking for: Where is the fuse or heater relay on a VAZ 2109? Answer: there is no fuse and heater relay for VAZ 2108, 2109, 21099. Older models have an ignition relay, through which the stove is also powered, see photo below.
In the latest VAZ models, the stove is powered directly through the ignition switch.
How to remove and replace the block
Such an operation may be necessary if it is necessary to repair the power supply or replace it with a new unit. Even a novice driver can do this. You will need a 10mm wrench (it is best to use a socket or socket). Before removing the power supply, open the hood of the car's engine compartment.
Procedure for removing the power supply:
- Disconnect the terminals from the battery. This is necessary to prevent the possibility of a short circuit in electrical equipment.
- For ease of operation, remove the protective plastic top cover of the power supply unit.
- The block is secured to the body with two screws (they are removed with a wrench).
- Disconnect the connectors with wires. One of them is located in the engine compartment on the wide side of the block closer to the windshield. First, remove the rubber protective cover, and then, rocking it from side to side, disconnect the connector.
- The remaining connectors are located at the bottom of the power supply. To get to them, remove the two outer relays, painted black. After this, the power supply housing is lifted up and the remaining connectors are disconnected.
The unit is removed from the engine compartment for repair or replacement. Reinstalling it is carried out in the reverse order. In this case, pay attention to the rubber gasket between the power supply and the car body. It must be intact, without cracks or tears, otherwise it must be replaced with a new one. The gasket is needed to protect the power supply from moisture, which can cause a short circuit in the car's electrical circuit.
