Malfunctions and repair of the VAZ 2106 fuse box

The electrical circuits of VAZ 2106 consumers are protected by fuses located in a special block. The low reliability of fusible links leads to periodic malfunctions and malfunctions of electrical appliances. Therefore, sometimes it is necessary to change both the fuses and the unit itself to a more reliable one. Repair and maintenance of the device can be performed by each owner of the Zhiguli without visiting a car service.

Fuses VAZ 2106

In the equipment of any car there are various electrical appliances. The power circuit of each of them is protected by a special element - a fuse. Structurally, the part is made of a body and a fusible element. If the current passing through the fusible link exceeds the calculated rating, then it is destroyed. This breaks the electrical circuit and prevents overheating of the wiring and spontaneous combustion of the car.

Cylindrical fuse links are installed from the factory in the VAZ 2106 fuse box

Fuse Block Faults and Troubleshooting

On the VAZ "six" fuses are installed in two blocks - the main and additional. Structurally, they are made of a plastic case, fusible inserts and holders for them.

Fuse blocks VAZ 2106: 1 - main fuse block; 2 - additional fuse block; F1 - F16 - fuses

Both devices are located in the cabin to the left of the steering column under the dashboard.

How to identify a blown fuse

When malfunctions occur on the "six" with one of the electrical appliances (wipers, heater fan, etc.), the first thing to pay attention to is the integrity of the fuses. Their correctness can be checked in the following ways:

• Visually;
• a multimeter.

Visual inspection

The design of the fuses is such that the state of the fusible link can reveal the performance of the part. Cylindrical type elements have a fusible connection located outside the body. Its destruction can be determined even by a motorist without experience. As for the flag fuses, their condition can be assessed through the light. The fusible link will be broken at the burnt element.

Determining the integrity of the fuse is quite simple, since the element has a transparent body

Diagnostics with a control panel and a multimeter

Using a digital multimeter, the fuse can be checked for voltage and resistance. Consider the first diagnostic option:

1. We select the limit on the device for checking the voltage.
2. We turn on the circuit to be diagnosed (lighting devices, wipers, etc.).
3. In turn, we touch the probes of the device or the control to the contacts of the fuse. If there is no voltage at one of the terminals, then the element under test is out of order.

Fuses, a very easy and quick way to check!

Resistance check is performed as follows:

1. Set the dialing mode on the device.
   

   To check the fuse, select the appropriate limit on the device
2. We remove the element for testing from the fuse box.
3. We touch the probes of the multimeter with the contacts of the fuse-link.
   

   We carry out a check by touching the fuse contacts with the probes of the device
4. With a good fuse, the device will show zero resistance. Otherwise, the readings will be infinite.
   

   An infinite resistance value will indicate a break in the fusible link

Causes of fuse failure

If the car fuse is blown, then this indicates a particular malfunction. The element in question may be damaged for one of the following reasons:

• poor connection with the contacts of the block. With an unreliable connection, not only damage to the protective element is possible, but also melting of the plastic elements of the fuse box as a result of overheating;
• installation of an element with a lower rating. If a fuse is used in a circuit with more current than its rated rating, then it will simply blow out;
• current surge in the electrical circuit;
• an error was made during the repair.

If the fuse block is damaged, it must be replaced with a good one.

A short circuit, which leads to a sharp increase in current in the circuit, is also the cause of blown fuses. Often this happens when the consumer breaks down or accidentally shorts the wiring to ground during repairs.

Replacing the fusible link

If the fuse is blown, then the only option to restore the circuit to working capacity is to replace it. To do this, click on the lower contact of the failed element, remove it, and then install a working part.

To replace a blown fuse, it is enough to remove the old element from the clamps and install a new one.

How to remove the fuse box "six"

For dismantling and subsequent repair or replacement of blocks, you will need an extension with a head for 8. The procedure consists of the following steps:

1. We unscrew the fastening of the blocks to the body.
   

   The fuse box is attached to the body with brackets
2. We remove both devices.
   

   Unscrew the mount, remove both fuse boxes
3. To avoid confusion, disconnect the wire from the contact and immediately attach it to the corresponding contact of the new node.
4. If only the additional unit needs to be replaced, unscrew the fasteners to the brackets and reconnect the wires to the new device.
   

   The lower block is fixed on a separate bracket

Fuse box repair

The occurrence of malfunctions in the VAZ 2106 fuse box is inextricably linked with a malfunction of a particular consumer. Therefore, first of all, you need to find the cause of the problem. Repair of blocks must be carried out, adhering to several recommendations:

• you always need to remove the negative terminal from the battery;
• plastic elements must be dismantled carefully to prevent their breakage;
• when replacing faulty fuses, do not install parts designed for higher or lower current, as well as use foreign objects instead of them (coins, wire, self-tapping screws, etc.).

Do not use coins or wire instead of fuses.

If, after replacing the protective element, a repeated burnout occurs, then the malfunction may be due to problems in the following parts of the electrical circuit:

• wiring;
• consumer;
• generator or battery;
• the fuse box itself.

One of the frequent malfunctions of the VAZ 2106 fuse blocks and other "classics" is the oxidation of the contacts. This leads to failures or malfunctions in the functioning of electrical appliances. To eliminate such a problem, they resort to removing oxides with fine sandpaper, after removing the fuse from its seat.

Sometimes the contact strip of the fuse box needs to be cleaned with sandpaper from oxides

Euro fuse box

Many owners of "sixes" and other "classics" replace standard fuse blocks with a single unit with flag fuses - the euro block. This device is reliable and easy to use. To implement a more modern unit, you will need the following list:

• open-end wrench for 8;
• flat screwdriver;
• a piece of wire for making jumpers;
• connectors "mother" by 6,6 mm in the amount of 12 pcs.;
• new fuse box.

To install the euro block on the VAZ 2106, you will need the fuse box itself, jumpers and terminals

The procedure for replacing the fuse box is as follows:

1. We remove the negative terminal from the battery.
2. We make 5 connecting jumpers.
   

   To install a flag fuse box, jumpers must be prepared
3. We connect the corresponding contacts using jumpers in the euro block: 3-4, 5-6, 7-8, 9-10, 12-13. If your car has rear window heating, then we also connect contacts 11-12 to each other.
   

   Before installing a new type of fuse box, it is necessary to connect certain contacts to each other
4. We unscrew the fastening of the standard blocks.
5. We reconnect the wires to the new fuse box, referring to the diagram.
   

   We connect the wires to the new unit according to the scheme
6. To make sure that the fuse links are working, we check the functioning of all consumers.
7. We fix the new block on the regular bracket.
   

   We mount a new fuse box in a regular place

So that the fuse block of the VAZ "six" does not cause problems, it is better to install a more modern flag version. If for some reason this cannot be done, then the standard device must be periodically monitored and any problems eliminated. This can be done with a minimum list of tools, following step-by-step instructions.
