Cigarette lighter VAZ 2105 wiring diagram

So, I bought a DVR, but it didn’t want to be powered by the cigarette lighter =(. I tried to connect other chargers and devices, but nothing worked. It turned out that they just don’t reach “+”.

I decided to replace the cigarette lighter with a Euro one. I bought a regular Euro cigarette lighter at the nearest spare parts store.

— First, you need to disconnect the terminal from the battery to avoid a short circuit. — We remove the central panel (clock, cigarette lighter, etc.) — It is necessary to sharpen the hole for the new cigarette lighter, because it is thicker. — First, insert the outer plastic ring of the backlight (it should snap into place. You can attach it with glue) — Next, insert the core. — We connect all the wires and return the central panel to its place.

I recommend immediately taking the cigarette lighter plug. There will be three wires there. So from left to right: The first wire is the backlight (yellow) The second wire is “+12v” (red or blue) The third wire is ground (black)

If you have any doubts, be sure to

check the voltage with an ammeter.

Also, I strongly do not recommend

, connect the cigarette lighter directly from the battery, because the cigarette lighter works by short-circuiting.

If there is no wire or another reason, then when wiring a new wire, be sure to

install a fuse in this circuit. (8A will do).

The car device has rich functionality. In addition to its usual task, you can connect the following to the VAZ 2107 cigarette lighter socket:

• charger for a phone, tablet or other electronic device;
• compressor for inflating wheels;
• navigation complex;
• DVR.

It turns out that even non-smoking car owners use the cigarette lighter. If it stops working, it can cause significant inconvenience. Read the article about the reasons for the failure and how to properly change the device on a VAZ 2022 with your own hands.

Reasons why the cigarette lighter does not work

There are certain factors that affect the performance of a part. You need to understand the structure of the cigarette lighter and understand why it does not work on the VAZ 2107.

Among the most common problems it is worth noting.

1. Fuse failure. If one or more powerful devices are launched into the cigarette lighter socket, the circuit current may exceed a critical value. At 10 Amps the fuse element will burn out. Additionally, the clock and radio will stop working. The repair is carried out simply according to the scheme - just get to the mounting block and replace the blown cigarette lighter fuse.
2. Bad connection. Over time, the contacts oxidize, causing the cigarette lighter to stop working. The reason for the appearance may also be the connection of a fuse with a high resistance, for example, a 15-amp one. If the VAZ 2105 cigarette lighter stops working, you must first remove the metal cartridge and check its contacts for the presence of oxides. During repairs, it is recommended to clean the contact areas. Before replacing the cigarette lighter or fuse, you need to remove the negative terminal from the car battery. This circuit will eliminate the possibility of a short circuit.
3. Burnt out filament element. On the classic, inside the cartridge there is a nichrome spiral, which can burn out due to age. Repairing the fault consists of replacing the cigarette lighter and installing a new element according to the diagram.
4. Due to old age or due to the fact that the wires can short out, there is a possibility of electrical wiring breaking or circuit burnout. The fuse trips. Such a malfunction of the VAZ 2107 cigarette lighter is diagnosed using a multitester. It is necessary to ring the circuit, diagnosing the integrity of the wires. In this case, it is the wiring that needs to be repaired or replaced, not the incandescent element.

VAZ 2105 cigarette lighter does not work

When developing the car, the designers provided one cigarette lighter connector located on the front panel.
Today it is practically not used for its intended purpose, but is useful even for non-smoking drivers. The cigarette lighter socket on the VAZ 2105 is a 12-volt outlet where you can connect various electrical appliances. Most often, they install a video recorder that records movement, a GPS navigator, or a charger for phones or tablets. Less often - a compressor for inflating wheels, an electric kettle, a car vacuum cleaner or a heated mug. Over time, the device may stop working. How to remove and repair the cigarette lighter with your own hands on the VAZ 2105 model is described below.

Causes of malfunction

• It often happens that the VAZ 2107 cigarette lighter socket is a socket, as described above. The calculation scheme is simple: by multiplying the maximum current for which the fuse is designed (10 A) by the voltage of the on-board circuit (voltage 12 V), we get 120 W. If this is not just a socket, but a splitter, you need to remember this. The fuse will burn like a match (at best), and repairs will become commonplace. A load of no more than 100 W works well.

• Sometimes the contacts of the cigarette lighter itself or its connector become oxidized. Then they are cleaned, having first reset the ground to avoid a short circuit. Replacement is not necessary at all; anyone can do the repair themselves.

• The next possible failure is that many additional devices do not fit tightly into the cigarette lighter socket, contact with the walls is poor, a “chatter” begins, and a short circuit occurs. After this, the contacts melt and the cigarette lighter does not work. If the contacts are melted, repairs can be made by cleaning and re-soldering them, or replacement is required. In this case, large peak loads occur on the fuse.

• Finally, sometimes the coil on the cigarette lighter itself may simply burn out. In this case, you just need to replace the head with a new one. If you can’t find a spare part, you can carry out a simple repair - clean the cigarette lighter coil from soot and carbon deposits.

Electrical diagram for connecting the cigarette lighter VAZ 2107

Before you remove the device and begin repairing it, you should understand its structure. The connection diagram for the cigarette lighter is described in the photo. It is the same for all classic VAZ models, including modifications 2104, 2105, 2106 or 2107.

The pinout is done as follows:

• the red wire controls the voltage for the clock and is connected to the battery;
• the yellow element also goes to the plus of the battery, it supplies power to the socket illumination light;
• the black wire is ground.

The cigarette lighter connection diagram is carried out through a mounting block with fuses. To get to it (when replacing the safety element), it is necessary to remove the panel located in the front part of the cabin. Fuse No. 6, rated for a current of 10 Amperes, is responsible for keeping the circuit circuit closed.

Cigarette lighter VAZ 2107 (2105, 2104) connection diagram

A cigarette lighter is installed on the center console of the front panel of the VAZ 2107 (2105, 2104).
Here is a diagram of its connection with a description of the elements and the order of operation (what happens when turned on and off).

Cigarette lighter for VAZ 2107 (2105, 2104) car connection diagram

Description of the cigarette lighter connection diagram

— The body of the cigarette lighter is its “ground” (a black “negative” wire is attached to it).

— The metal rod at the bottom of the cigarette lighter body is its positive contact.

— In the on-board network of the VAZ 2107 (2105, 2104) car, voltage is supplied to the cigarette lighter directly from the positive terminal of the battery through terminal “30” of the generator and the mounting block. Regardless of turning the key in the ignition.

— The electrical circuit is protected by fuse F6 10A (No. 6 10A) in the mounting block.

— Inside the cigarette lighter there is a heating element installed - a spiral made of nichrome filament, which has a certain resistance.

— The cigarette lighter is turned on by pressing its button. As a result, it is recessed into the inside of the body. In this case, the plus and minus of its electrical circuit are closed through the spiral. Electric current begins to flow through it, causing heating. After 15-20 seconds, the temperature of the coil reaches the desired value, the bimetallic claws holding the cigarette lighter from heating open and the return spring pushes it out of the socket. The electrical circuit is broken. That's it, you can safely light a cigarette.

— The clock and radio tape recorder hang on the same fuse as the cigarette lighter.

Notes and additions

— The positive contact of the cigarette lighter is constantly energized, regardless of whether the ignition is on or not. This should be taken into account when carrying out repair work on the electrical equipment of the car.

— Quite often, the positive wire of the cigarette lighter is used by the driver to connect additional devices he needs or simply to supply voltage to the electrical circuit of various consumers of the on-board network where his positive has disappeared somewhere. When making such alterations, these should be taken into account. that the cigarette lighter fuse is only 10 A and may not withstand a heavy load.

Lada 2107 › Logbook › 1. Problem - once. Cigarette lighter and voltage.

Friends! Owners of VAZs and non-VAZs, thinking and non-thinking people, I ask you to help me figure out the puzzle of this “white imaginary” 2107... =) Problem:

— the cigarette lighter does not work.

The bottom line is this: We have a standard circuit in which I measured the voltage:

Blue wire

, or black in the photo - this is the “negative” wire - the working one. The yellow wire is the “plus” wire that is connected to the light bulb, and the voltage to which is supplied when the dimensions are turned on. The red wire is the “plus” wire that is connected to the cigarette lighter socket. Poidee is a constant plus, because... The cigarette lighter works independently of the ignition switch.

Using a multimeter, I got the following values: On the yellow wire, the voltage is 11V. On the red wire - 1.2V

And I measured it twice. As indicated in the diagram in Part A and Part B, i.e. in the place where the wiring is connected, and in the cigarette lighter contact. The result is the same 1.2V. — I assumed that the wire was faulty. I took the plus from the light bulb - yellow. Included dimensions, i.e. applied voltage, but the cigarette lighter did not work. I took the plus from the glove compartment light - it didn’t help.

-The cigarette lighter is faulty -The wiring is faulty -Both If it’s wiring, then where should we get the “red plus” from?! Yes! And this phenomenon is also confusing:

The cigarette lighter doesn't work, the light inside is on, the cigarette lighter itself doesn't heat up, I tried to charge the navigator, no reactions, what could it be? Is it the cigarette lighter itself or maybe the fuse?

The light bulb goes separately. The cigarette lighter plus goes to the mounting block Sh4-4 contacts, and connects to fuse 6. See fuse, Connector Ш4 contact 4, and also ground.

thanks, I'll watch it!

The light bulb goes separately. The cigarette lighter plus goes to the mounting block Sh4-4 contacts, and connects to fuse 6. See fuse, Connector Ш4 contact 4, and also ground.

and where is the mass from it?

I looked at the fuse - it’s normal, not blown, he took out the cigarette lighter itself, everything seems to be fine, the wire is connected and where is the ground for it?

there was a problem with the cigarette lighter, I suffered for 2-3 weeks, burning so many fuses, in the end I bought a new one assembled for 150 rubles, installed it, everything works

Why did you blow the fuse? and how many amperes should it stand there?

According to this diagram No. 30, the ground of the cigarette lighter is connected to the folder and the mother. Through these connectors it goes to the rear window heating relay, and also on this wire there is a parallel wire on the connector, which comes in relation to the ground (a white wire with a black stripe, or vice versa). Red with a blue stripe goes to Sh4-4contact, this is the positive output from the mounting block, and the positive input to the cigarette lighter goes to the mounting block with the battery, the pink wire of the Sh10-1contact connector (note that this wire is connected to another positive wire, see the contact there). Make a test lamp and check for fuses, and at the cigarette lighters itself there is a plus, so you will know whether there is a plus or not, and then you can see a lot if everything is in order there.

It turns out there is no wire on the nut at the back of the cigarette lighter, how can I re-stretch it?

If it's on the nut, then it's a plus, you can take it from the ignition switch, but most likely your stock one just burned off and is lying around somewhere under the panel

well, that's a plus! I'll try to find it! And if I don’t find it, can you make it easier?

I explained to you that your plus for the cigarette lighter comes from the mounting block Ш4 (the connector marking is indicated either on the connector itself, or on the mounting block next to it) - contact 4, so shoot from it to your cigarette lighter, also this wire connect with a chip to the cigarette lighter wire chip (folder, female) the marking of your wire (does not always match, 99%) is red with a blue stripe.

If the cigarette lighter stops working, then the most likely reason is a blown fuse, of which there are several. The nest itself also often burns out. Or maybe a foreign object just got into the cigarette lighter. To find out what the problem is on your car, read the article.

When looking for the reason why the cigarette lighter does not work, always start by checking the fuses and then move on. The table briefly shows the locations where fuses are usually located on popular brands of cars. Although, of course, it is best to use the diagram specifically for your car.

Where are the fuses on other cars - look on our website, and you can find out the reasons in the comments

If the problem of a non-working cigarette lighter cannot be solved by replacing the fuse (it is intact), then you will find the answer below in more detail about universal methods for checking and troubleshooting. But to find out the reason why the cigarette lighter stopped working, figure out how it works and how it works. After all, it often intersects with the radio and even the clock.

How the cigarette lighter works and its connection diagram

The main element of the cigarette lighter is its socket, into which both heating elements and plugs of various devices powered by a 12V network are inserted. Ground from the battery is supplied to the socket, and the plug has a positive contact. When you insert a connector into a socket, the circuit is completed and power is supplied to the devices.

How does a car cigarette lighter work?

Cigarette lighter power circuit

If there is a backlight, it is powered by a separate wire suitable for the socket. Power is supplied through wires, which, on the one hand, are connected through a chip to the mounting block with fuses, and on the other hand, through another chip, to the terminals of the cigarette lighter housing.

To avoid short circuits, the cigarette lighter socket always has a fuse in the fuse box. It also has another additional fuse on the body. By the way, the backlight has a separate fuse.

An important point - why does the cigarette lighter constantly work when the ignition is off? This is not a malfunction, it is a feature of its connection according to the diagram. For example, this is how the cigarette lighter works in VAZ Classic, VAZ-2114, Lada Kalina, BMW E34-E36, Skoda Octavia Mk2, SEAT Leon I and some others. But this doesn't always happen.

The cigarette lighter does not work when the ignition is turned off in VAZ-2115, BMW E39 and newer, Volkswagen Touareg, Opel Corsa and others. By the way, judging by the forums, in the same LADA models, the device may or may not work when the ignition is turned off.

VAZ-2105 diagram

Information on the “five” schemes is intended for self-repair of a car in case of minor problems with electrical equipment. The electrical circuits are divided into several blocks (for ease of viewing via a computer or phone), there are files in the form of a single picture with a description of each element - for printing on a printer. Years of production of this model: from 1979 to 2010. At the end of December 2010, AvtoVAZ stopped producing it due to low demand for the VAZ-2105 model. By this time, 2 million cars had already been produced.

Locations of problems and reasons why the cigarette lighter stopped working

As can be seen from the operating diagram, the cigarette lighter will stop working if the contact breaks or deteriorates anywhere in the electrical circuit. Therefore, if the cigarette lighter does not work, the reason may be this:

• there are foreign objects in the cigarette lighter socket that interfere with contact or lead to a short circuit;
• the socket burned out as a result of a short circuit, due to the fact that there is no tight contact between the antennae and the plug inside - either the contacts became bent over time, or the plug was loose, or the contact was lost when driving on a bumpy road;
• the fuse in the fuse box has burned out;
• the fuse on the cigarette lighter housing has burned out;
• there is no voltage supplied to the cigarette lighter plug: the wires are disconnected or burned out;
• the tracks in the mounting block have burned out (a common problem on the VAZ-2114 and VAZ “Classic”).

Burnout location in the cigarette lighter socket

This element is responsible for lighting the cigarette lighter, which often fails

The main problem with most electrical appliances that we connect to a socket is the lack of a clear global standard for plugs and sockets. This is why short circuits occur, which kill the cigarette lighter.

The second global reason is that many electrical appliances connected to the cigarette lighter (compressors, vacuum cleaners, refrigerators, etc.) consume current above 20A, while on average it is designed for 15-20A. So often the system can't handle it and burns out at its weakest point, which is usually the fuse.

An option to solve the problem is to cut off the cigarette lighter plug on powerful devices, attach crocodile pliers and connect directly to the battery.

By the way, it's a bad idea to connect the radio to the cigarette lighter. Although it does not consume as much current, it still takes some of it, and when connecting powerful electrical appliances, the likelihood of burnout is higher. Yes, and the radio may be damaged.

Also, do not exclude from the list of reasons the usual breakage of wires due to physical wear or vibration.

What to do when the cigarette lighter does not work

As already stated at the beginning, the most likely reason for a cigarette lighter failure is a blown fuse. Therefore, we take out the manual for your car, look for the fuse diagram and find the one that is responsible for powering the cigarette lighter socket. It can be either separate or combined with other systems (often it is marked in the form of a cigarette or the inscription Cigar).

“Ring” the desired fuse with a multimeter or test lamp to see if it is working. If there is no device, and the fuse itself does not have obvious signs of burnout, try replacing it with a similar one and checking the cigarette lighter. If it works, change the fuse. No - we are looking further.

Ringing cigarette lighter contacts using a multimeter

The second place that is quite easy to check is the cigarette lighter socket. Carefully inspect it for foreign objects or burn marks on the sides. Further actions will require disassembling the panel and removing the cigarette lighter socket, as well as the presence of a multimeter or at least a test lamp. Don't forget to first remove the negative terminal of the battery!

Disconnect the chip with the cigarette lighter connector from the body and ring the contacts (if necessary, turn on the ignition). If voltage is present, carefully inspect the housing. There may be plaque or oxide on the terminals and connectors of the cigarette lighter, which can be removed with a cotton swab dipped in alcohol (wait for it to evaporate before turning on the device). If this does not help and the socket is clearly burnt out, then only replacing it will help.

The next element that needs to be carefully inspected is the fuse on the cigarette lighter housing. Most often, it has a 90-degree curved shape and connects the cigarette lighter contacts. If it burns out, the problem can be solved using a soldering iron or replacing the housing. In most cases, it is enough to solder or screw a piece of wire (aluminum with a cross-section of 1.5 mm2), which will close the contacts and act as a fuse.

If, when the fuse is working, the “ringing” of the chip with connectors indicates a lack of voltage in the network, then the problem is either in the wires or in the fuse mounting block, in which the conductive paths burn out. Moreover, in domestic cars it is most likely tracks, and in foreign cars it is wires.

To finally verify this, you can go in two ways:

1. Disassemble the mounting block and inspect it for damaged tracks. Don't forget to take pictures of how it was originally. If the tracks are damaged, they need to be soldered.
2. Find the electrical diagram of the car, find the connectors that come out of the mounting block to the cigarette lighter and ring them. If the voltage goes out and the cigarette lighter does not work, you will have to change the wire, which is quite difficult. If there is no voltage, the problem is in the mounting block.

What to do if the cigarette lighter on VAZ cars does not work?

Since the cigarette lighter socket most often refuses to work for owners of domestic cars, below are some useful tips specifically for VAZs.

Start by inspecting the fuse. It is located in the mounting block in the engine compartment - the exact location can be seen in the diagram of your model:

• VAZ-2104, 2105, 2107 - F6 (8A/10A)
• VAZ-2115, 2114, 2108, 2109, 21099 - F7 (30A) or F4 (20A)
• VAZ-2101-2103 and 2106 - F1 (16A) and the entire 110 family - F6 (15A)
• Lada Kalina and Granta - F20 (15A)
• Lada Priora - F13 (15A), Lada 4x4 - F14 (16A)
• Vesta - F41 (20A)
• Largus - F19 (10A), F20 (7.5A) and F38 (15A)
• Xray (XRAY) – F33 (15A)

Ringing the cigarette lighter fuse using a homemade tester on a VAZ 2107

To determine if the cigarette lighter is faulty on a VAZ, ring the block (black - minus, red - power supply plus, white - plus when the lights are on)

If the fuse is working, also check if there is voltage in its socket.

The next step is to check if there is power at the cigarette lighter terminals. If your cigarette lighter only works when the ignition is on, turn the key in the lock. When the multimeter does not show 12 volts, then the problem is most likely in the tracks of the mounting block. Disassemble it and solder the burnt tracks. Well, if the multimeter shows that there is power, you need to change the cigarette lighter housing itself.

What to do if the cigarette lighter light does not work

As mentioned above, the cigarette lighter light has a separate fuse and a separate wire to supply current to the light bulb or LED. Therefore, first check the corresponding fuse, and if it is ok, disassemble the cigarette lighter and check the wire - most likely it just fell off. There is nothing to burn out here, so the problem can only be in these two places.

How it works and its purpose

The device is extremely simple: it is a car socket connected to the car's on-board power supply, and a heating element located in a remote socket. The heater is a nichrome spiral pressed into a ceramic core. The remote cartridge, receiving power, heats up the filament.

Functions and operating principle

In addition to its intended use, you can connect many external devices to the VAZ cigarette lighter socket, as well as:

• charge mobile devices;
• connect a DVR, navigator, car vacuum cleaner;
• turn on the source of external lighting (carrying);
• power the compressor to inflate the wheels.

The device consists of two detachable parts, each of which has its own functions:

Having received power, the spiral heats up and, having reached a given temperature, acts with heat on the bimetallic plates that hold it. The plates are deformed under the influence of high temperature and release the cartridge. It is pushed out of the socket by a spring and takes its original position. When the cartridge is locked, the cigarette lighter lamp lights up, signaling that the device has entered operating mode.

Why doesn't the cigarette lighter work?

Fuse blown

Unreliable contact

The cigarette lighter connectors are susceptible to oxidation. If the reason for the lack of power is oxidized terminals, they must be cleaned by first disconnecting the negative bus from the battery.

Burnt out filament element

Nichrome wire serves as an incandescent element and over time can burn out and fail. It is not advisable to disassemble the cigarette lighter cartridge in order to repair it; you need to purchase a new element.

Broken electrical wiring

Lack of power may be due to a break in the electrical circuit.

Wires can break due to engine vibration or friction against the vehicle body.

The device, wiring diagram for electrical equipment of the VAZ-2105 and wiring are similar to other models; you need to find the break point, clean it and connect it. It would not be superfluous to solder the twisting point and securely insulate it.

What to do

The cigarette lighter is not directly responsible for the operation of any component of the car, but its operation negatively affects the comfort of the driver and passengers of the car. If the device is damaged, it must be repaired or replaced.

Where is the fuse for the cigarette lighter?

The VAZ-2107 cigarette lighter fuse is located in the fuse and relay mounting block. In VAZ cars this block is located in the engine compartment on the passenger side. To gain access to the fuse, you must remove the transparent plastic cover of the mounting block. The cigarette lighter fuse is marked F 6 and is rated for a current of 10 amperes.

How to disassemble the cigarette lighter

• remove the heater cartridge from the socket;
• we pick up the panel on which the clock and cigarette lighter are located and drag it with a flat-head screwdriver until the latches click;
• carefully remove the dashboard; there may be short wires behind it;
• remove the dashboard connection terminals;
• unscrew the locking nut;
• remove the outer casing along with the backlight;
• remove the internal cigarette lighter socket.

Replacement

Which to choose

If for some reason the cigarette lighter stops working, the car owner believes that the color of its backlight does not match the design of the instrument panel, or there are simply not enough sockets for the simultaneous operation of all necessary devices, the device can be replaced with a splitter with several standard sockets.

When developing the car, the designers provided one cigarette lighter connector located on the front panel. Today it is practically not used for its intended purpose, but is useful even for non-smoking drivers. The cigarette lighter socket on the VAZ 2105 is a 12-volt outlet where you can connect various electrical appliances.

Most often, they install a video recorder that records movement, a GPS navigator, or a charger for phones or tablets. Less often - a compressor for inflating wheels, an electric kettle, a car vacuum cleaner or a heated mug. Over time, the device may stop working. How to remove and repair the cigarette lighter with your own hands on the VAZ 2105 model is described below.

Installation of Euro cigarette lighter VAZ 2105

The standard format of the device is already outdated. The old connector does not fit well with the plugs of modern electrical appliances. Therefore, many owners replace it with a Euro-type cigarette lighter for the VAZ 2105. The cost of a device of this format is 600-900 rubles. It fits perfectly into a regular place and also provides reliable fixation.

The replacement process is carried out as follows.

1. Remove the terminal from the battery.
2. We dismantle the facing panel.
3. Open the ashtray and unscrew the mounting screws.
4. Disconnect the wire block.
5. Remove the housing with the light bulb from the cigarette lighter. To do this, squeeze the locking tendrils and then pull up.
6. Use a flat-head screwdriver to pry the socket out, removing it from its seat.
7. We install a new Euro sample cigarette lighter. If necessary, it is worth modifying the seat with a file, expanding it to the required diameter.
8. We are making a connection.
9. We assemble and check the functionality of the unit.

It is important to remember the connection diagram. In total, three wires come to the device: two pluses (heating the coil, backlight), ground, powered through the car body. A detailed video on how to remove the cigarette lighter on a VAZ 2105, replacing it with a Euro version is presented below.

It seems that grief is not enough for the non-smoking driver, may the gods be with him, the repairs can wait. But the problem is that, due to the peculiarities of connecting the cigarette lighter in the VAZ 2107, the car radio (or radio tape recorder) does not work with it, as well as the car clock with its backlight.

With the advent of the third millennium, the problems became even greater: a mobile phone charger, a VCR, a mini-TV and even a small refrigerator are connected to this outlet. This is not at all scary, but some lazy drivers have stopped carrying a hand or foot pump and only use electricity from the same source. This is where problems begin on the highway due to a flat tire. You should vote "ask for a pump".

What comes to mind is replacing the cigarette lighter on everyone's favorite VAZ 2107, or at least repairing it. But first, let's figure it out and look at the car cigarette lighter connection diagram.

Why it might not work

The device is a simple device consisting of a metal rod and a socket to which wires are connected, where it is inserted. Inside the VAZ 2105 cigarette lighter itself there is a thin nichrome spiral. By pressing the button, the driver puts the device into working condition, the contacts close, and current begins to pass through the thread, heating it. After 15-20 seconds, the temperature reaches its maximum, the thermal relay is activated, returning the cigarette lighter to its place. Due to age or improper use, the device may break. If the cigarette lighter on a VAZ 2105 does not work, you should check the following places.

1. The appearance of plaque. If liquid gets onto the contact points of the cigarette lighter, rust can appear, and long periods of inactivity can lead to the formation of oxides. This will disrupt the normal operation of the contacts and may also cause a short circuit. It is necessary to periodically remove the cigarette lighter, and then inspect its contact points for oxides or foreign deposits. If necessary, you should arm yourself with sandpaper or a file, with which you can remove the rust, reaching the metal base.
2. Loose connector. Some VAZ models are equipped with an old-style cigarette lighter with a long tip. The plugs of modern electrical appliances are not designed for such a socket and quickly loosen it, bending the fixing tendrils. To repair, you need to pull out the rod and then tighten the elements inside the cartridge. Before this, you should de-energize the circuit by disconnecting the terminal from the battery or pulling out the fuse.
3. Faulty backlight lamp. There is a light around the nest, making it easier to find at night. Age may cause the cigarette lighter bulb to burn out. In this case, it is necessary to dismantle and replace the faulty element with a new part.
4. Burnt cigarette lighter coil. Due to constant heating and cooling, the thread located inside the cigarette lighter simply burns out, breaking the circuit. You can try soldering the ends, but this idea is impractical - it is better to change the entire cigarette lighter.
5. Faulty fuse. Each segment of the vehicle's electrical network is protected by a special element. It burns out when the current exceeds the maximum value, protecting the cable insulation from melting and the cigarette lighter wiring from burning out. The maximum permissible parameter for this section is 10 amperes. Repairing such a fault is simple - under the hood of the car there is a mounting block where you need to get to and change the part.
6. Short circuit. If the cigarette lighter fuses start to burn one after another, this means that there is a short circuit running through the network. We turn off the engine, turn off the ignition, and then measure the battery voltage. Then turn on the ignition and take measurements again. A difference in readings of more than 0.5 volts indicates the presence of a “short”. We arm ourselves with a tester and look for a faulty cord that should be replaced.
7. Broken cigarette lighter wiring. The VAZ 2105 is an old car, the wires of which may fray or solder joints may fall off. It is necessary to inspect the cables - no melted insulation, creases or breaks are allowed. It is worth ringing the cords with a tester, setting it to measure resistance. All soldering points must be restored using a blowtorch and tin, and broken wires must be replaced with intact ones.

The fuse must have blown

An element can fail for various reasons. Most often this is a short circuit or connecting too powerful devices. This segment is protected by a 12 amp fuse. This means that the maximum power of the connected devices is 120 Watts (P=I (12 volts) *A (10 amperes). A hint that it is the protective element that needs to be changed will be a non-working socket for a portable lamp or a faulty clock.

Replacing the VAZ 2105 cigarette lighter fuse is simple - you need to get to the mounting block, pull out the element and install a new one. It is located under the hood, on the right side along the direction of the car (see photo). There is a diagram on the top cover, and inside there are tweezers that make it easy to pull out parts. We remove element number F6, rated 10 amperes.

The old-style mounting block contains ancient cylindrical fuses. New models are equipped with modern knife parts. When installing, be sure to install a fuse with a rating of 10 amperes. Otherwise, if a short circuit occurs, the cables will overheat, the insulation will melt, and there is a risk of fire in the wiring.

Now you can start repairing or replacing the VAZ cigarette lighter. Assembly and installation of the device follows the reverse procedure for removal.

Replacing the cigarette lighter on a VAZ 2105

There are two ways to replace the cigarette lighter on a VAZ 2105, but before you start working with any electrical appliances on the car, disconnect the negative wire (ground) on the battery.

First method: First, you need to remove the installed cladding panel. Then open the ashtray, take a shaped screwdriver and unscrew the fastening screws - remove the ashtray from the central panel.

Secondly, having disconnected the electrical wiring, unscrew the round nut on the back of the cigarette lighter.

Thirdly, remove the spiral from the cigarette lighter and the body of the light bulb (to remove the body with the light bulb, squeeze and pull up, the antennae will shrink and it will come out), and then remove the back cover.

Fourth, use a thin flat screwdriver to remove the cigarette lighter and the backlight ring.

Assembly is carried out in reverse order. Install the backlight ring with the cigarette lighter. Then insert the back cover of the cigarette lighter, take the housing with the light bulb and, squeezing the antennae downwards, stick it in place. Install the spiral and fiber washer and, holding it, apply special thread glue to the threads - tighten the round nut at the back of the cigarette lighter. Connect the cigarette lighter wiring plug. Install the ashtray on the central panel - tighten the fastening screws and install the facing panel. Connect the negative wire (ground) of the battery. Check the operation of the devices and the cigarette lighter. All the work is done through the hole in the ashtray and therefore not everyone can get their hands through it.

There is a second method that is more labor-intensive, but also effective:

Remove the steering shaft housing by unscrewing the five screws using a flat-head and shaped screwdriver. Remove the plugs from the instrument panel (the dashboard where the speedometer is located) and unscrew the screws to remove it, disconnect all the wires and the speedometer. If there is a headlight hydraulic corrector, remove the handle from it, unscrew the fastening nut and remove it from the instrument panel.

Unscrew the screws and remove the lower parcel shelf on the passenger side and the storage compartment (glove compartment). Remove the handles from the heater control levers (to do this, at the junction of the handle with the lever, use a thin screwdriver or knife to bend the lower part of the upper and middle handles, and the upper part of the lower one) and remove the lining of the heater control levers. Remove the radio panel by unscrewing the fastening screws.

Remove the four screws securing the bottom of the center panel. And through the holes in the glove box and the dashboard, unscrew the four screws securing the upper part of the central panel. Having disconnected the top insert on the central panel, move the panel towards you and unplug the plug from the cigarette lighter.

Remove the cigarette lighter as in method one. Reassemble in reverse order. Install the cigarette lighter by placing the housing with the bulb and tightening the rear round nut. Connect the plugs to the cigarette lighter and begin assembling the central panel. Push the center panel into place and tighten the four screws securing the center panel through the holes in the glove compartment and dashboard. Also tighten the bottom four screws securing the center panel. Screw on the top insert of the center panel.

Secure the radio panel by tightening the fastening screws. Tighten the screws, replacing the lower parcel shelf on the passenger side and the storage compartment (glove compartment). Install the handles on the heater control levers and its trim. Headlight hydraulic corrector - tighten the fastening nut and install it on the instrument panel, place the handle. Connect all the wires and the speedometer of the dashboard, screw it on and install the plugs. Install the steering shaft housing.

Connect the negative cable of the battery, check the operation of all devices and the cigarette lighter. Whenever working with electrical equipment of a car, follow safety precautions!
