Fuse box for VAZ 2110 - where is it located, replacement

This arrangement is similar to the models VAZ 21102, VAZ 21103 and VAZ 2112. The location of all fuse blocks in the car body Main unit

was placed in the most convenient place for the driver - on the left side of the steering wheel. It opens easily via a button under the headlight control.

Other two blocks

— located in the center console of the dashboard. One of the fuses is located separately from all the others (in a niche behind the main mounting block).

Let's look at each block separately and study it.

Introduction.

Have you checked the fuses? Isn’t this the phrase we hear most often from our comrades and repair advisors? Indeed, the VAZ 2110 fuse box protects each of the key elements of the electrical circuit and it is very worth checking them. But when is it really useful, and when can it be considered just a waste of time?

Fuse box VAZ 2110

It doesn’t matter which element of the car has failed: it could well be a broken starter, dead wipers or headlights, for example. Checking the protection circuit is the fastest and most effective way to start repairs.

But if the fuses in your car “like” to blow out often, are they really needed? Is it possible to refuse unwanted “protectors”?

In the inquisitive mind of a motorist, many specific questions arise regarding the maintenance and repair of his iron horse. Quite tricky in some places, very interesting in others. Even about the usual VAZ-2110 safety block you can write a lot of useful information. Perhaps you didn’t know something or were embarrassed to ask. We tried to answer various useful questions in this thematic article.

Recommendations for use

In order not to cause harm to the elements of the electrical circuit, never insert wire or other bugs in place of a burnt-out element.
Before replacement work, de-energize the system by turning off the ignition, and in some cases, disconnecting the negative terminal of the battery.
Replace elements using plastic tweezers, which should be included in the kit.
When replacing, be sure to look at the rating of the fuse you are replacing; if it was 16 amps, then change it exclusively to 16 amps. Otherwise problems may arise. If you put it with a rating below 16 A, it may burn out immediately. And if it is higher, then it will not be able to protect the corresponding consumer during a power surge.

Component functions

Each element of the block is responsible for its own electronic unit. A blown fuse or damaged element can lead to malfunction of the vehicle's lighting system, power system and other volatile devices.
Each electronic device in a car unit plays a very important role. If you suspect a malfunction, it is necessary to change it as soon as possible, so that on the road the car does not present you with a surprise in the form of a malfunction.
If the car does not have an injector, but a carburetor, then the car will be able to work with a damaged or inoperative fuse block, but there will be no idle speed and other components may not function fully.
When the unit burns out, the central locking and alarm system stop working, so the car must be parked in a safe place during this time.

Location

The relay and fuse mounting block is located on the left side of the steering column in the instrument panel.

Causes of failure

Fuse and relay block VAZ 2110

There are also not many reasons for breakdowns. There are only two of them:

Defect due to production. Quality companies do not allow their products to have any flaws. Therefore, defective goods are sorted and thrown away. However, Chinese firms neglect this.

Note: Without wanting to install a low-quality unit on your car, you should pay attention to it at the time of purchase.

In addition, the unit may fail due to the fact that a short circuit has formed in the system. But it happens because the fuses are not in order. However, choosing high quality fuses (see VAZ 2110: how to replace fuses) for your car is not as easy as it seems at first glance. Recently, you can increasingly find fuses from “left-wing” sellers. You should avoid them.

Installing Blade Fuses

Such fuses are much better than conventional ones, as they have many positive properties. They have better contact with the socket into which they are inserted. Due to this, they retain their positive qualities for a long time, so they are not in danger of melting or heating. To install them you need to have:

A screwdriver that can be used to remove the terminals.
Key for 8
Heat shrink
Female connectors
Block
Wire to make jumpers

The installation itself is carried out as follows:

Disconnect the negative terminal of the battery so that a short circuit does not occur in the system.
A size 8 wrench will allow you to easily unscrew the fasteners from the block.

Note: It is very important that the wires do not fall off the terminals.

When the block is unscrewed, it must be weighed down until it stops. But you need to act carefully so that the wires do not break.
Make jumpers.
Install blade guards.
Return everything to its place.

Why doesn't the cigarette lighter work?

On the VAZ-2115 the device stops working due to the following reasons:

Fuses blown. The cigarette lighter in domestically produced cars often shorts out, and the protective parts have to be changed regularly. This is considered a design flaw that is difficult to eliminate.
Connecting too powerful devices to the socket. Burnout is caused by the insertion of a plug into a car vacuum cleaner or compressor.
Changing the state of the nest. With frequent use, it becomes loose, the block dangles, which provokes a short circuit. In this case, the fusible protective elements quickly burn out. The absence of a beep helps determine the malfunction (the fuse-link is loaded with sound devices).
Fan motor short circuit. Standard devices are unreliable and quickly break down. In this case, the cigarette lighter does not work on the VAZ-2115.
Burnout of the track in the installation block due to a short circuit. When the pads are exposed to moisture, the contacts become covered with an oxide film. The fuse box is the weak point of a domestic car.

Fuel system.

If the starter in the car is spinning at full strength and a good spark is observed in the ignition system, then possible problems with starting the engine may be associated with the fuel system.

If your car is equipped with electronic fuel injection, then several of its subsystems may specifically cause the power unit to fail to start.

True, it should be noted here that in most of these cases you simply will not be able to independently diagnose all kinds of electronic systems and subsystems, which may actually be the reason for the failure to start the engine. The point is this: this check requires special diagnostic equipment, which is only available in car service centers or car service dealerships.

True, there are some moments when you can check certain subsystems yourself in a garage. And all this thanks to certain and specific methods of such checking. Although you will not find the specific cause of the breakdown, in any case you will significantly narrow the scope of the search for this malfunction, which will save you a lot of money when you go to a car service for electronic diagnostics of the car.

— Electrical connections: There are many electrical connections in the fuel injection system. Each fuel injector has its own connector on top. There are electrical connectors in the air system of the car, as well as on the cylinder head. You should check all the electrical connectors that are under the hood of the car. This is quite difficult, we understand, but nevertheless, you will save a lot of money on this, which you can then give to a car repair shop without regret.

— Fuel pump and relay: To check the fuel pump you will need special equipment that diagnoses the vehicle's fuel system (pressure). Since most of us motorists do not have this kind of equipment, all we can do ourselves is to completely check all electrical connections.

For example, check the flow of electrical current on the positive wire that powers the fuel pump itself. To do this you need an electrical tester. Before checking, make sure the ignition key is in the “On” position. If the tester shows that current is flowing to the pump, then proceed to the next troubleshooting step. If there is no current and does not flow, then you need to check the fuse. If the fuse is in good condition, then the problem with starting the engine is in the fuel pump relay itself. Replace this relay with a new one.

— Fuel filter: If the fuel pump is working correctly, this does not mean that fuel is getting into the engine in the normal sufficient quantity. For example, due to this fuel filter, fuel may not flow into the combustion chamber in sufficient quantities, which may cause the power unit to fail to start. In order to avoid such problems, you need to change the fuel filter in your car every 20 thousand kilometers, which can be heavily contaminated with enzyme-forming substances present in the fuel itself.

You can easily check all these elements in the car yourself and, if necessary, replace them yourself, specifically using everyday auto tools. Unfortunately, there are many other fuel electronic systems that simply cannot be checked without the use of special equipment. Therefore, remember, our dear motorists, to do electronic diagnostics of a car, it is best to trust specifically to professionals and contact a car service center.

Mounting block for VAZ 2110: fuse diagram

The mounting block is presented in the form of a black box. Unlike airplanes, you can gain access to a car “black box” at any time the car owner needs. This unit is of great importance because it combines all the electrical components of your VAZ 2110.

In simple terms, the mounting block is a console with a board inside. It contains fusible links - fuses. Plus there are relays there.

Standard mounting block

The design is designed in such a way that the driver has the opportunity to independently replace a failed component. To do this, remove the broken fuse and insert a new one in its place. They cost pennies, but can seriously affect the performance of the equipment.

Since the release of the VAZ 2108, the domestic manufacturer has significantly improved the unit, making it resistant to vibrations and shaking.

To figure out how, if necessary, replace fuse F6 or any other of the 20 pieces that are provided on the VAZ 2110, you need to determine the location of the mounting and additional blocks, and also understand the diagrams.

More about this in our material today.

Replacement example

Since all fuses are located in a common block, the replacement principle is the same for all. Therefore, we can consider an example of only one element that needs replacement. Let this be the cigarette lighter. It is designated F6 and F18 (see table).

The first priority before replacing a fuse is to check its functionality. Many people immediately change the element without even considering whether the problem of the unit failure really lies in it.

Remove with tweezers

To check the fuse, you should perform several step-by-step operations:

Start the car by turning the key in the ignition;
Make sure that the cigarette lighter is inside its socket, where it should be;
Wait about 20 seconds;
Take out the cigarette lighter and check if it is warm. If the temperature remains the same, that is, the element is cold, then the fuse needs to be changed.

How to do it? Pretty easy.

Get to the panel on which the board with the relays and cigarette lighters is located. The mounting block is located, as you remember, to the left of the steering wheel, at the bottom of the dashboard.
By pressing the special latches, the cover will move away from its seat. Be careful not to break the latches.
The mounting block has now opened in front of you.
If you look at it carefully, you will see special tweezers on the edge. It is provided by the factory in order to carefully remove fuses and insert new elements in their place.
Remove the affected fuse. In this particular situation, we are talking about the cigarette lighter fuse, so you need an element designated F6 or F18.
This component burns out due to the fact that modern motorists need additional electrical equipment, such as vacuum cleaners and electric pumps. All this is connected to the fuse and overloads it. Hence the frequent breakdowns.
Using the same tweezers, insert a new fuse with the same parameters indicated on the mounting block.

If for some reason you don't have tweezers inside your black box, small pliers can serve as an alternative to this tool. Never try to remove the elements with your fingers. The nests are quite fragile, and with your hands you can only loosen it and damage it.

Replacing relays and fuses is a simple and inexpensive repair. But if you damage the block itself, then you will have to spend more, and you will definitely have to work hard.

Are fuses repairable? No. These are fusible elements that simply become deformed when burned. Therefore, repair is possible only in one option - replacing blown fuses.

Location

Since AvtoVAZ engineers tried to do everything so that car owners would not have problems replacing relays and fuses, it would be stupid to come up with a clever arrangement. Therefore, finding them is not difficult.

The main unit is located to the left of the steering wheel;
You will find the first additional block in the dashboard inside the niche, directly behind the main mounting block;
The second additional block is located in the same place, only on the opposite side.

We will get acquainted with each block separately so that you do not have any confusion when searching for one or another fuse.

On injection engines with 16 and 8 valves, the location of the MB is identical, so the instructions are equally relevant for owners of both versions of the dozen.

Main MB

Relays and fuses are located here. Let's look at their descriptions in more detail and separately.

Found the main MB

Let's start with the relay.

Designation	What is he responsible for?
K1	Car lamp operation
K2	Electric windshield wipers
K3	Special relay that interrupts the turning lights when the hazard warning lights are activated
K4	Turning on the low beam
K5	Turning on the high beam
K6	Area for installation of additional device
K7	Rear window heating operation

Fuse diagram

Next comes the fuses. They are located in the same place, but are designated by the letters F.

Each fuse is indicated with a current rating and designation. This allows you to use a new fuse with parameters that meet the requirements of the equipment connected to it.

Designation	Rated current	What is he responsible for?
F1	5A	Lamps for license plate illumination, instrument panel illumination, indicator lights on the instrument panel, left side position lights, luggage compartment illumination
F2	7.5A	Low beam left headlight
F3	10A	Left high beam
F4	10A	Right front fog lamp
F5	30A	Electric door windows
F6	15A	Carrying lamp, cigarette lighter
F7	20A	Radiator fan, horn (horn)
F8	20A	Heated rear window
F9	20A	Windshield wipers and washer
F10	20A	Backup fuse
F11	5A	Right dimensions
F12	7.5A	Low beams in the right headlight
F13	10A	High beams in the right headlight
F14	10A	Left fog lamp
F15	20A	Heated seats in the cabin
F16	10A	Hazard signal, turn signals
F17	7.5A	Stop signal, ignition switch illumination, interior lighting
F18	25A	Interior heater, glove compartment light, cigarette lighter
F19	10A	Reversing light, brake light monitoring
F20	7.5A	Rear fog lights

First additional block

Inside the central panel there is the first of two additional blocks provided for the VAZ 2110. You can find it at the bottom left on the front passenger side.

This block provides three fuses. Each of them has the same power rating - 15A.

The first fuse is responsible for your vehicle's ignition and controller module.
The second protects the mass air flow sensor, heating sensor, speed sensor and purge valve.
The third is necessary to ensure protection of the injectors, as well as the fuel pump. So if problems arise with the fuel pump, the first thing we recommend is to check the condition of the fuse responsible for it.

Additional block location

Plus, the same block includes three relays:

Relay number 4 is responsible for the electric fan;
Relay number five is the electric fuel pump;
The third relay is part of the ignition protection group on your VAZ 2110.

Second additional block

The second additional block should be looked for already in the driver’s feet, on the right. Behind the protective cover on the console you will find the required board.

There are three more components on it. They are responsible for:

Immobilizer operation;
Additional optics (mostly fog lights);
For the operation of the car's central locking control.

Replacement example

Remove with tweezers

To check the fuse, you should perform several step-by-step operations:

Start the car by turning the key in the ignition;
Make sure that the cigarette lighter is inside its socket, where it should be;
Wait about 20 seconds;
Take out the cigarette lighter and check if it is warm. If the temperature remains the same, that is, the element is cold, then the fuse needs to be changed.

There are times when, for no apparent reason, the windshield wipers stop functioning, the rear and front turn lights do not turn on, the fuel pump does not turn on, or the cigarette lighter coil simply does not heat up. In this case, do not rush to run to the store to buy a brush motor or spend money on light bulbs or other devices. Most likely, it's all about blown fuses or relays. You need to carefully study the fuse block diagram of the VAZ 2110 and then you can easily fix this problem.

All electrical consumers in a car are protected by small and very simple devices - fuses. In particular, thanks to these simple devices, in the event of an increase in voltage, the wiring will not burn out, but the circuit will simply break. Each electrical fuse or relay is designed for a specific amperage and has an individual purpose. In some cases, one fuse controls several devices, for example, a cigarette lighter and other equipment.
