Mounting block with fuses for VAZ 2109 (diagram)

Print this article Font size 16

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.

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.

In the engine compartment


The module is represented by a complete collection of fuses and relays.
To gain access to the panel, you will need to unclip the plastic clasps of the cover and remove it from the fastenings. Inside you can find two configurations of components - this depends on the year of manufacture of the car. All elements responsible for protecting the main power circuits of the car are introduced here.

Diagram of the mounting fuse block for VAZ 2109, 2108, 21099 (block 17.3722)

In the diagram: (the outer number in the designation of the wire tip is the number of the block, and the inner number is the conventional number of the plug)

K1 — rear window washer time relay; K2 - relay-interrupter for direction indicators and hazard warning lights; KZ - windshield wiper relay; K4 - relay for monitoring the health of the lamps (contact jumpers are shown inside, which are installed instead of the relay); K5 - headlight high beam relay; K6 - relay for turning on headlight wipers; K7 — power window relay; K8 - horn relay; K9 - relay for switching on the electric motor of the engine cooling fan; K10 — relay for turning on the heated rear window; K11 - relay for low beam headlights.

Reasons for premature failure of fuses

Factors can be identified.

  1. Moisture getting into electrical contacts. This can cause a short circuit and a voltage surge.
  2. Damage to on-board wiring or serviced mechanisms. In such cases, sharp surges and voltage fluctuations occur in the wiring section. As a result, the fuse blows.
  3. Setting the fuse element to a too low rating. Some users may mistakenly insert a fuse that is too weak into a loaded circuit. After activating the device, the insert will immediately fail.

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.

In the cabin

There is no installer inside the machine. Instead of the usual cabin module, it uses individual elements and relays scattered throughout the car. They can be found everywhere, under the dashboard, inside the doors, on the gearbox pipe. The reason for this decision was simple savings. The manufacturer considered that installing a separate module into the car would be too “kosher” and scattered fuses wherever possible.

Elements responsible for circuits of equipment not related to the engine are mounted here.

General characteristics of the model

Dream car in the 90s

The dimensions of the car have changed somewhat due to the lengthening of the wing and enlargement of the hood. In addition, a completely new, improved VAZ radiator grille and, of course, an updated dashboard appeared. The length of the VAZ 21099 compared to other cars in this group has increased by 20 cm.

The VAZ 21099, like other models of this family, has many advantages:

  • it is capable of developing a fairly high speed;
  • has excellent controllability when driving;
  • Stable on completely different types of roads.

In 2004, this model of car was no longer produced in Russia, but its production continues in Ukraine.

VAZ 21099 cars come in two types.

The VAZ 21099 has a carburetor, just like the VAZ 21099 has an injector, the layout of the fuel supply system is almost identical.

In the VAZ 21099 injector, the supply of gasoline when you press the gas pedal is controlled by a computer. In a carburetor engine, such emissions are controlled by special damper plugs.

Quite often, the owners of this car are faced with one problem: the VAZ 21099 carburetor cooling fan does not work.
