VAZ 2110 cigarette lighter fuse and relay: how to remove and replace

Almost all car owners, including non-smokers, use this device. The cigarette lighter socket is used as a 12-volt socket for connecting various electrical devices:

fan;
compressor;
navigator;
DVR;
charger for phone or laptop.

VAZ 2110 models are equipped with long, old-style cigarette lighters. Their disadvantage is that they do not provide reliable fixation of connected devices that are designed to meet European standards. As a result, the devices sometimes short out and refuse to work correctly, causing the fuse to trip. Some owners decide to replace the cigarette lighter with Euro standards in the VAZ 2110. The following are instructions on how to change the device to a short one with your own hands without the help of a specialist, and install a new fuse.

Required Tools

Before dismantling the cigarette lighter on a VAZ 2110, repairing it or installing a new device, or replacing a fuse, you will need to stock up on suitable devices. To work you will need:

Phillips and standard screwdriver;
protective gloves.

To fix a broken cigarette lighter or fuse, the following will be useful:

multitester;
blowtorch with solder;
heat shrink tubes, electrical tape;
wire cutters;
needle file

Required spare parts

To operate, you will need an assembled unit. Factory models with article number 2108-3725010 are recommended for replacement. It was borrowed from the G8 line, but it fully supports the functionality of other models. You can replace the cigarette lighter of a VAZ 2110, 2111 or 2112 with euros. Article 11.3725. Prices for an assembled unit average about 400 rubles.

Why did the cigarette lighter break?

Over time, the device may stop working. The most common reasons why a VAZ cigarette lighter breaks.

Blown fuse. The element protects the circuit from wire melting or fire. If the maximum permissible current parameters are exceeded, the fuse fails. It is necessary to remove it from the mounting block. Fuse F18 should be replaced with a serviceable element with the same rating (25 amperes).
Cigarette lighter wiring broken or short circuited. If a car fuse burns frequently, it means there is a short in the circuit. This failure should be diagnosed using a multitester. The wires coming to the cigarette lighter are tested for resistance. The fuse blows.
Poor contact. Over time, the connector on the VAZ 2110 may become loose and the contacts may oxidize, not guaranteeing a good connection. The repair is simple - you need to remove the cigarette lighter from the socket, process the contact points with a file and bend them for better fixation of the device.
Burnt out spiral. The metal thread located inside the device on the VAZ 2110 can burn out due to frequent thermal exposure, and the fuse trips. It is worth replacing the cigarette lighter.
A burnt-out backlight bulb in a VAZ 2110. There is additional lighting around the device itself to help you find the device in the dark. Over time, the light bulb may also stop lighting and the fuse will trip. You will need to remove the burnt element and then replace it with a working one.

How does a cigarette lighter work?

The device system is quite simple. The principle of operation is as follows.

A spring-loaded lid with a filament extends into the interior. When it is pressed, the working element heats up. After sufficient heating, the key snaps out of the groove and the cigarette lighter cover rises. Then it can be removed and used for its intended purpose.

Checking the condition of the wiring and contacts

If the device does not work correctly or fails altogether, you should check the entire circuit, including protective elements. Typically, diagnostics are performed in the following sequence:

remove the dashboard;
find two wires connected to the cigarette lighter;
inspect the joints for damage, oxides, melting;
Next, you should follow the line to the fuse box and find the required fuse link and check its condition.

Let's summarize

Obviously, the procedure for replacing the cigarette lighter is quite simple, even a beginner can do it. But you need to understand that the cigarette lighter will have to be changed often if the current consumption increases above 25 amperes. Once this value is reached, the entire procedure described above will have to be performed again, since the node will inevitably fail. The most common reason for this is connecting multiple devices at the same time. You should not use tees, and you should always know exactly how much the device you want to connect to the cigarette lighter consumes. This will extend the life of both the unit itself and the fuses.

Maybe the fuse has blown?

Before removing and replacing the VAZ 2110 cigarette lighter, you should check the serviceability of the protective element. This is a fairly common failure. The car circuit in this area is protected by a 25 ampere fuse. This means that devices with a total power of more than 300 W (12 volts * 25 amperes = 300 watts) cannot be connected to the socket.

Otherwise, the fuse on the VAZ 2110 will blow out. A hint that it was he who “gave up” is the failure of the heater fan. If the device does not work, the fuse should be replaced. The location of the mounting block is to the left of the steering column, behind the decorative panel trim.

To make it easier to pull out the fuse, you should use tweezers. It is necessary to change the part with index F-18. The fuse rating is 25 amperes. It is prohibited to install parts designed to carry high current. An unsuitable fuse may result in a short circuit, damage to wiring cables, or fire.

Location of fuses on the diagram for VAZ 2110

The main unit is located behind a protective cover that protects it from moisture, dust and dirt. Location: near the left foot at the bottom of the dashboard. The main fuses and fusible links of the car are concentrated here. The console controls most of the car's electrical equipment.

There are also auxiliary blocks - one is located in the niche of the gearbox housing and contains mainly protective relays. It can be found behind the plastic cover on the left side of the front passenger footwell.

Which fuse is responsible for the cigarette lighter?

The car circuit has a number of fusible links responsible for protecting the on-board circuits. Insert F18 is responsible for the cigarette lighter device. The fuse has a rated limit of 25 Amps. It is quite easy to find the part in the main fuse box. She is located in the bottom row, third from the right.

Fuse blown

When such a breakdown occurs, the entire system stops working. Any manipulations of the car enthusiast remain without reaction or response. If the insert burns out, check the lines and contacts for short circuits. Only after eliminating the breakdown can you change the VAZ 2110 fuse.

Replacing the fuse

To change a burnt-out element, follow a simple procedure:

find the required insert;
carefully remove the damaged part from the socket;
inspect the nest for damage or burns;
insert the new fuse into the seat.

Important! It is strictly not recommended to pull out the fuse by swinging it - this can damage the socket or tear off the thin leg, which will cause even greater damage. For replacement, special forceps or tweezers are used.

Causes of device malfunction

Generator VAZ 2110 2111 2112 Generator VAZ 2110 2111 2112

The cigarette lighter may need to be replaced if the product stops functioning. The reasons for mechanism failure are the following factors:

The socket fuse has blown. Occurs in frequent cases if the outlet is used to connect several devices as a splitter. After all, a 10-amp fuse is not designed for large current overloads, so in frequent cases it fails. In order to repair the cigarette lighter, you simply need to replace the fuse with a new one.
Oxidation of device contacts. To carry out repairs, you will need to remove the mechanism and clean the contacts.
Closing the contacts of the product. Contact melting occurs when inept owners replace a 10A fuse with a 15A one. As a result, this leads to the wiring in the car “burning” or the contacts melting. To fix the problem, you need to remove the device and make repairs based on the breakdown.
Faulty filament coil. In order to repair the product, it is necessary to replace the head with a new one. The cost of the product does not exceed 150 rubles.

If the product is used frequently, it may fail. According to the instructions, the cigarette lighter head should snap out when you press it after 10-20 seconds. Over time, this period of time increases, and at one point the product stops functioning altogether. Let’s find out in more detail what the connection diagram for the cigarette lighter on a VAZ “classic” is.

Cigarette lighter electrical circuit

The cigarette lighter socket of the “seven”, like any other inexpensive car, has the following connection diagram:

“Power” is a red wire, one part of which powers the clock in the car.
The yellow wire is the power supply for the backlight.
“Ground” is a black wire.

The fuse, which is responsible for protecting the product, is located in the mounting block at number 6. In modern cars, power to the cigarette lighter usually comes not directly from the battery, but through the ignition switch. As a result, power is not supplied until the ignition key is turned. This is done in order to preserve battery charge during long periods of parking.

Let's find out how to change the cigarette lighter on a VAZ 2107, and what the procedure is.

Features of device replacement

Self-replacement of the mechanism is carried out as follows:

First you need to remove the negative terminal from the battery. After this, dismantle the panel with the clock.

The plus filament is located in the center and is connected to the cigarette lighter power line coming out of the fuse box.
The third contact is intended to supply power from the vehicle's side lighting.

Important! The standard block 2110 is not suitable for working with the Euro module. To do this, just find a contact connector in any auto store.

How to correctly connect the cigarette lighter directly to the battery via a fuse

It is enough to perform a simple sequence of actions.

Route the power line to the battery under the hood.
Connect the line securely to the battery terminal.
Next you need to insert a fuse into the system. It is usually placed directly in front of the device.
It is also useful to install a switch or relay here. To be able to accurately control the activation and deactivation of equipment. Typically, users connect the relay to the ignition switch. Thus, only after turning the key in the cylinder, the device will be powered.
The final step is connecting the wiring to the device.

Instructions

If you determine that to fix the problem it is necessary to remove the cigarette lighter, then you should begin this work. This is done in the following order:

First, remove the negative terminal from the battery. You will be working with electricians, so you need to avoid short circuits as much as possible;
From the central tunnel, unscrew the 2 screws that are located near the dashboard;
Unscrew the side panels of the central tunnel. They are secured with self-tapping screws; this must be done on both sides;
The pads that power it and the backlight are turned off;
Find the decorative trim under the handbrake lever. Pry it off with a slotted screwdriver;

Remove the cigarette lighter socket. Along with it comes the light bulb screen;
Locate and release the cigarette lighter latch. As a result, it should move forward a little and disengage with the body;
Pull out the cigarette lighter itself;
Squeeze the latches on the light guide. They are easily compressed, and as a result, the cigarette lighter is disconnected from the light guide panel.

This completes the work. All that remains is to install the new device in place. This is done in reverse order.

There are several ways to extend the life of a new cigarette lighter. If you do not follow these tips, you will be changing this device regularly. Here are the most important points:

The most important thing is not to allow the current consumption to exceed. In the case when you connect tees to the cigarette lighter, most likely you will simply ruin it. The cigarette lighter is not designed for such loads. Never connect several devices to it at the same time;
It is also worth choosing fuses carefully. They only look completely identical. In fact, they may differ slightly from one manufacturer to another. But even a difference of half an ampere can be critical. Therefore, purchase fuses only from proven brands;
If
a fuse is blown, it is worth checking all the wiring that touches it. Often it is also damaged, and subsequently it can affect the operation of the cigarette lighter, or cause the fuse to re-blow.

As you can see, problems with the cigarette lighter, although not common, do occur. Therefore, you need to know how to properly diagnose, as well as how best to avoid problems. Knowing how to remove the cigarette lighter on a VAZ 2110 and 2112 will make your task easier when you need to replace a faulty device. Despite the fact that this repair is one of the simplest, it also has its own characteristics that are worth considering. Otherwise, you will lose a lot of time and may break other structural elements. When performing work, be extremely careful and careful.

How to quickly remove the cigarette lighter of a VAZ 2110

There is an easier way that allows you to remove the device without dismantling the tunnel. You can quickly remove the device on a VAZ 2110 as follows:

We de-energize the circuit.
We dismantle the metal cartridge.
Using scissors or a minus screwdriver, we tighten the fixing antennae inside the cartridge and pull it out.
Unclip the wire block.
We dismantle the plastic filter, carefully prying up its edges.

The video will help you understand how to remove the cigarette lighter and replace the fuse on a VAZ 2110 car.

Car cigarette lighter device

A car electric cigarette lighter consists of two parts: a socket and a socket. To light a cigarette, use a cartridge with a heating element. A bimetallic relay is mounted in the socket, which regulates the heating temperature of the coil. Thus, the electrical circuit of an electric cigarette lighter consists of a socket, a bimetallic relay, and a socket with a heating element. The device is connected to power via a fuse. The electric cigarette lighter is mounted together with a backlight lamp. Therefore, replacing at least one component will require dismantling the entire structure.

Car cigarette lighter device

Between lighting the cartridge is in the socket, the electrical circuit is open. To light a cigarette, the user pushes the cartridge into the socket, which closes the electrical circuit. After 15-20 seconds, the spiral heats up and heats the socket body. When a sufficient temperature is reached, the bimetallic plates of the relay diverge, the circuit opens, and the cartridge is pushed out of the socket. You can light a cigarette.

Changing the cigarette lighter light bulb

Sometimes the backlight of the device burns out and the fuse trips. This will require dismantling the filter and replacing the light bulb. It’s easy to do work on a VAZ 2110.

Remove the terminal from the car battery.
We take out the metal cylinder.
We bend the fixing antennae and remove the device from the hole.
Disconnect the wire block.
Remove the filter ring.
We squeeze the lamp screen so that the legs come out of the slots.
Remove the light bulb by turning it 90 degrees.
We install a new element, and then assemble the device, following the reverse procedure.

Removing the cigarette lighter socket

The process of dismantling the seat is carried out in the same way.

We de-energize the system by removing the negative terminal from the battery.
It is necessary to disassemble the side cover to disconnect the wiring plug.
Dismantle the gearbox casing and parking brake tunnel.
We bend the plastic screen so as to pry off the fixing tabs.
We remove the cigarette lighter socket through the opening with the wiring block.
We inspect the device and proceed to replacement.

Connecting an additional cigarette lighter

Some car owners install another socket. You will need:

drill or screwdriver with a set of metal drills;
a crown for cutting out a hole, the diameter must match the diameter of the car cigarette lighter;
file;
soldering iron with solder;
wire cutters;
screwdrivers;
multitester;
heat-shrink tubing;
wire of suitable cross-section;
fuse that can withstand the current recommended by the manufacturer - 25 amperes.

Procedure.

We turn off the power to the car and choose a place to connect an additional cigarette lighter. It is desirable that it be a flat surface.
We drill a hole of a suitable diameter and clean the edges with a file.
We connect to the wiring, observing the polarity and passing them through the fuse.
We check the functionality of the model and carry out assembly.

Frequent problems and ways to solve them

Before changing the cigarette lighter, you should inspect other common breakdown areas. It may be possible to repair the part without replacing or dismantling it.

Frequent problems include:

Blown fuse. To check this element, you need to connect a standard 12-volt lamp to the socket, and then turn the ignition key. If the lamp does not light, the fuse has blown. It needs to be removed and replaced. You need to get to the block under the front panel and remove the non-working element.
Loose or oxidized contacts. It is necessary to check the connectors of the VAZ car cigarette lighter for the presence of rust, tighten them for tight contact.
Fallen wires. There is an age issue that should also be taken into account. To eliminate this, you should solder them to their seats.
Burnt out spiral. Treated by dismantling and installing a new nest. To extend the lifespan, it is advisable not to connect devices with high current strength, such as a compressor for inflating tires.

How to connect the device to a cigarette lighter without a plug

Some owners decide to abandon the device itself and prefer to install other devices directly. To connect the device directly without a plug you will need:

blowtorch, solder;
screwdriver.

Procedure.

We dismantle the car cigarette lighter, gaining access to the cables.
We connect the wires of the installed device, observing the polarity.
We carry out the assembly.

Connection diagram.

Checking the serviceability of the cigarette lighter

First of all, the serviceability of the mechanism is determined by checking the fuse, which is located in the corresponding block. Element marking – F18. The maximum possible current passing through the fuse is 25 amperes.

You can check the node in another way. To do this, turn on the stove. You may quite reasonably wonder what the connection is.

Both systems operate via one fuse. If the fan is not working, it's time to replace the fuse element. Otherwise, most likely there is a break somewhere in the wiring. This usually occurs between the fuse box and the cigarette lighter. But before starting replacement work, make sure that the fuse marked F6 is working. This element can also affect the operation of the cigarette lighter.

Cigarette lighter not from ignition

There is a way to connect directly to the car battery. This scheme has advantages: if you connect the cigarette lighter directly to the battery, you can avoid interfering with the wiring itself and the fuse. The work will take less time; the positive cables should be led directly to the battery, and the negative cables should be attached to the car body.

It is also important to remember that you need to select the right spare parts. Initially, this concerns the wires. Each square millimeter of cross-section is designed for 5-10 amperes of current. Should be taken with reserve. A cross-section of 3–5 mm is quite sufficient to transmit the required voltage. Otherwise, the wires may burn and the fuse will trip. This will result in a risk of short circuit. The circuit should be routed through an additional fuse with a rating specified by the manufacturer.

Check and replacement

Replacing the cigarette lighter in a VAZ 2110

Turn on the ignition.
Insert the cigarette lighter into the socket.
Wait 10-15 seconds.
Take it out.

Note: if it has not warmed up during this time, then it really does not work.

Replacing the cigarette lighter for VAZ 2110

Of course, you can go to a dealership to have it replaced by a qualified automotive technician, but you can also replace and install it yourself to save money. Replacement instructions:

First you need to find a fuse (see VAZ 2110: how to replace fuses) that protects the cigarette lighter from spontaneous combustion. To easily remove it, you need to break the chain.

Note: Removing the fuse is important because if the wiring located at the top is tangled, it can cause damage to other electrical things in the car. The wiring will simply burn out and will need to be replaced. Before you begin replacing the fuse that protects against spontaneous combustion, you should read the machine's user manual.

Now you have to remove the faulty device. To do this, you need to take a flat screwdriver and insert it into the slot (the cigarette is placed there). The screwdriver needs to be turned several times.

Note: this should be done extremely carefully so as not to tear out the socket, since in this case the other cigarette lighter is unlikely to function normally.

The process of replacing the cigarette lighter of a VAZ 2110

If this method does not work, you will have to try to release the metal clips that hold it in place.

Note: these clamps are very easy to unfold, but there is no need to rush. It is better to do the work longer, but with better quality.

VAZ 2110 how to remove the cigarette lighter

After removing it, you will have access to two wires with spade connectors. You need to remove both wires so that they are completely disconnected.

Note: if they are not turned off, they may short out and catch fire during operation.

Now it will be much easier to replace this device. It is necessary to connect the spade-shaped connectors to the peaks located on the back of the device. You need to insert the black into black and white into white wires accordingly.

Note: otherwise the circuit will not be closed and the device will not work.

After connecting the wires, you can install it in place by pushing it into the hole provided for this.

Note: Press it lightly and then twist it clockwise until it is secured by the two metal clips. He must be motionless.

Now all that's left is to replace the fuse in the fuse box (if it doesn't work) or install the old one.

Note: this is a prerequisite, since without it a short circuit is possible.

Replacing the cigarette lighter yourself

The most common and minor breakdown in a car occurs due to the cigarette lighter. Many car enthusiasts who don’t even smoke face this problem, because modern devices used in the car are all charged from the cigarette lighter. This includes a telephone, a navigator, a recorder, an electric pump, refrigeration equipment and much more that is needed on the road.

With so many necessary things, the cigarette lighter often fails, so it must be handled with special attention. But if it does break, then how to solve this problem? Let's take a closer look at this.

How to check

Finding out whether the cigarette lighter in your car is working is easy. The first sign of a breakdown is lack of response when connecting external devices. Associated symptoms manifest themselves in the form of the clock, dashboard backlight, radio and other standard devices turning off.

To check the functionality of the part, remove the mounting block and evaluate its condition. The placement of the block depends on the design features of the machine. In VAZ cars it is located on the front panel.

If the cigarette lighter does not work even though the fuse is working, pull out the wires and check their integrity with a multimeter.
