Fuse Location

For ease of maintenance, most fuses are installed in a special mounting block, and here the VAZ-2115 injector is no exception. You just need to know that this model has two of them installed.

The first one in the VAZ-2115 (equipped with an 8-valve engine) is located directly in the cabin, under the dashboard, at the steering wheel. The other one is installed near the engine, that is, under the hood, next to the left glass.

Any of the fuses located in the mounting block has its own specific designation, based on this, it is not difficult to find out which circuit it is responsible for. So the fuse is marked:

• K1 – protects the relay that turns on the headlight cleaning from overvoltage;
• K2 – for emergency signaling and switching of turn signals;
• K3 – power supply for the “janitors”;
• K4 – lighting;
• K5 – window regulators;
• K6 – horn;
• K7 – rear window heating element;
• K8 – high beam headlights;
• K9 – close;

Below are fuses with fuse links, which are designated F and have a serial number. Each of them is designed for a specific current.

The amperage is indicated at the top. They are placed in groups under the main fuse, and protect the individual circuits controlled by it.

The unit installed in the cabin is slightly different from the one described above. It contains, in particular:

• relays (3 pieces);
• ECU;
• fuses (3).

Each of the latter is designed to protect a specific circuit from overvoltage and short circuit.

Down up:

• on-board computer power supply (7.5 A);
• radiator cooling fan, and in addition an adsorber valve, mass air flow sensors, DC and DC sensors (7.5A);
• fuel pump (15 A).

As noted earlier, this block also contains three relays. Down up:

1. Basics.
2. Radiator fan control.
3. Responsible for the operation of the fuel pump.

How to remove the fuse and relay box for VAZ 2114, 2113, 2115 models 2114-3722.010

Removal of the mounting block of fuses and relays of the VAZ 2114 - 3722.010 model is carried out in the following sequence:

1. First, remove the minus terminal from the battery;
2. Then inside the cabin, on the left side, under the instrument panel, we remove 5 wiring harness blocks from the bottom side of the fuse and relay box;
3. After this, remove the cover of the mounting block. To do this, press the 2 latches of the lid.
4. Next, disconnect the wiring harness block from the top plane of the fuse and relay box
5. After this, use a 10mm socket wrench to unscrew the bolts securing the mounting block of the blade fuses
6. Raise the block and remove 4 more connecting blocks of wires
7. Then we remove the VAZ 2114-3722.010 fuse and relay block from its socket
8. After this, remove the gasket of the fuse and relay mounting block
9. We replace or repair the VAZ 2114-3722.010 fuse and relay box;
10. We install the block in the reverse order of removal.

Fog lights do not light up: causes and solutions

Fog lights are car lighting devices, the difference of which is the light they emit (it can be white or yellow). The peculiarity of the lanterns is that the outgoing beam does not rest on the fog, but spreads along the road, providing sufficient visibility to the car owner. How to adjust these headlights? Why don't the fog lights light up? How to fix the problem? Let's consider these points in detail.

Basic Rules

To ensure good visibility in heavy fog, it is important to follow the following rules:

• Adjust the edge of the light beam so that the light beam is above the horizontal plane.
• Install the lamp at a minimum distance from the road. This is necessary in order to simplify the adjustment of the light beam boundary.

If the headlights are well adjusted, they guarantee excellent visibility on the road, even in difficult road conditions.

To prevent deterioration in the quality of the glow, it is important to monitor the condition of the lampshade. If necessary, polish the surface and remove scratches, as they impair the performance of the flashlight

Adjusting the fog lights

Causes of breakdowns and solutions

Now let's look at why fog lights don't work, and what are the possible causes of such problems. As a rule, malfunctions of fog lights are caused by corrosive and oxidative processes. In addition, the reasons for PTF failure include:

• Fuse blown.
• No contact in the relay.
• Deterioration of contact to the “minus” of the body.
• Burnout of lamps.
• Oxidation of contacts.
• Incorrect connection.
• Deterioration of contact on fog lights.

To diagnose and fix the problem, you need a set of tools and a multimeter. The first thing to check is the integrity of the fuses that power the fog lights. If they are burnt out, replace them.

If the circuit fuses are good, check that the headlight bulbs are working. The simplest reason why the fog lights do not light up is that the lamps have burned out due to a short circuit or natural wear and tear. To check lamp integrity, use a known good light source

It is important that the lamp base is of the same type and dimensions as the failed part. After purchasing the required light bulb, replace it (this can be done without removing the headlight)

If all the work considered is completed, but there is no result, pay attention to the power button. Perhaps the reason why the fog lights do not work is hidden in it

If the button is defective, replace it. If the contacts become oxidized, clean them. In a situation where problems with the PTF appeared after self-connection, the causes of the malfunction may lie in incorrect connection of the circuit.

To repair the fog lamp, you may need to perform the following work:

• Glass replacement.
• Installing a new light bulb.
• Replacing the fog lamp frame after removing the bracket. Such work may be required if the cladding is damaged.

Before carrying out repairs, it is advisable to remove the fog lamp, for which you need to unscrew the screws securing it to the bracket. After this, disassemble the PTF to repair or install a new lamp.

An extreme case is to replace the fog lamp. It has to be resorted to in a situation where the unit does not work completely or the quality of the light beam has significantly deteriorated. During the replacement process, it may be necessary to remove the car's bumper, because it is in it that the headlight plug is located. As soon as you have access to the place where the light is installed on the bracket, use a special tool to unscrew the fastener, and then discard the plug and remove the headlight. If the fog lights do not light up and the unit is completely faulty, then install a new part.

Decoding the fuse and relay block VAZ 2114-3722.010

To change fuses in the mounting block, under the hood, there are tweezers.

A blown fuse cannot always be identified by a broken thread. When viewed through the lens, the thread may be intact, but inside the fuse, at the connection points, it may be torn. In this case, the fuse can be checked with a multimeter.

Before replacing the fuse, the cause of the blown fuse must be determined and eliminated. To avoid failure of elements of the engine control system, you cannot install fuses with an increased rating or homemade ones.
