How to attach the cigarette lighter to a VAZ 2105

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

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

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 light 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.

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!

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.

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.

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.
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.
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.
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.
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.
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.
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.

Features of the electrical equipment of the VAZ 2105 car

The electrical equipment of the VAZ-2105 car is made according to the classic single-wire circuit for the Zhiguli family, in which:

the metal body of the car plays the role of a second wire;
the negative terminals of all electrical devices and components are connected to ground;
electrical circuits are protected by fuses;
the operation of the main systems is activated through the vehicle's ignition switch.

For reference: the ignition switch controls electrical networks by supplying power from the battery or generator. The contact group of the lock is designed in such a way that when the engine starts, the electrical wiring of the VAZ 2105 secondary circuits is turned off.

Egnition lock

The ignition switch was used as a control system for the vehicle's electrical systems, which had four main positions:

Position “0” – everything is off.
Position “1” – ignition is on. The key is locked in the lock. In this case, with the key inserted, external lighting circuits, control devices and alarm lamps (brake fluid level, engine oil pressure, fuel level in the gas tank) can be activated;
Position “2” – turning on the starter. Auxiliary circuits and VAZ 21053 wiring that connects them do not work to facilitate engine starting;
Position “3” – parking. All circuits are turned off, and after removing the key, the steering column is locked.

For reference: the factory instructions inform you that, regardless of the position of the key, the interior lighting lamps, brake light lamps (when the brake pedal is pressed), the horn and the connector for connecting a portable lamp remain energized.

Fuse and relay box

To protect electrical circuits and devices, a fuse circuit is used to break the electrical connection. This happens when the voltage increases - the fuse-link melts due to temperature and the circuit is disconnected.

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.

Self-removal and installation of the VAZ 2105 cigarette lighter

During the work process you will need a set of tools. To replace the cigarette lighter of the VAZ 2105 model you need:

knife;
screwdriver;
gloves.

To repair the cigarette lighter you will need:

soldering iron;
pliers;
insulating tape;
tester;
heat shrink tubes;
spare parts.

You can buy both original and non-original parts on the market. The price of the element is 200 – 600 rubles. Article – PT 1001200.

The following are instructions on how to remove the cigarette lighter.

We open the electrical circuit of the car. To do this, you will need to open the hood and remove the negative contact from the battery. You can also remove fuse F6 from the mounting block.
We dismantle the facing panel.
Open the ashtray and unscrew the mounting screws.
Disconnect the wire block.
Remove the housing with the light bulb from the cigarette lighter. To do this, you need to squeeze the fixing antennae and pull up.
Use a flat-head screwdriver to pry the socket out, removing it from its seat.

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

Signs of trouble

There are several types of condition of the “five” electrical circuit when car owners have to look for a malfunction:

The car can't move. In principle, there can be many reasons for this. This could be a breakdown of certain components and mechanisms, or problems in the operation of the electrical circuit.
The car can be driven, but the electrical equipment is not functioning correctly.

Connection diagram for the instrument panel for the “five”
If you try to start the engine, this does not work, but gasoline flows into the unit without problems, most likely, the problem must be looked for in the circuit:

As mentioned above, injection versions are more complex in terms of electrical wiring and equipment. As practice shows, in most cases the problem lies precisely in the internal combustion engine control system. For example, if the vehicle system cannot process signals from the regulators and, accordingly, transmit signals to auxiliary mechanisms, most likely the problem is in the circuit.
If you have a carburetor “five”, then first you need to diagnose the spark plugs, as well as high-voltage circuits. It happens that high-voltage wires become bent or their contacts oxidize, which leads to problems in the operation of the car. In addition, it is advisable to check the functionality of the ignition coil and distributor.

In fact, on any version of the VAZ 2105, be it an injector or a carburetor, one of the main reasons for the incorrect operation of the equipment is contacts. They oxidize or burn, which can result in difficulties in the operation of equipment, in particular, interior lighting or external optics (video author - Max Rublev).

Additionally, to repair or tune a VAZ, you will need to know the serial numbers of the plugs in the blocks. The electrical diagram of the VAZ 21074 gives the following designations:

Headlights, windshield and headlight wipers, power supply valve control unit, windshield wiper relay.
Mounting block and three-lever switch.
Signal and turn signals.
Rear block lights.
Alarm switch.

Rules for safe use of the cigarette lighter

The device requires some care. To avoid the need for an unscheduled cigarette lighter replacement, you should adhere to the following rules:

It is prohibited to connect devices with a total power of more than 120 watts (compressors for inflating wheels, kettles) into the socket;
It is prohibited to install a fuse designed for a current greater than 10 amperes or install paper clips or wires instead of a protective element;
It is not allowed to close the contacts with a screwdriver or other metal objects;
It is periodically necessary to carry out preventive work, cleaning the contact areas from plaque or oxides, and bending the fixing tendrils.

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.

Remove the terminal from the battery.
We dismantle the facing panel.
Open the ashtray and unscrew the mounting screws.
Disconnect the wire block.
Remove the housing with the light bulb from the cigarette lighter. To do this, squeeze the locking tendrils and then pull up.
Use a flat-head screwdriver to pry the socket out, removing it from its seat.
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.
We are making a connection.
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.

Electrical diagram for connecting the cigarette lighter of a VAZ 2107 car

There are slight differences depending on which model of center console is installed on the vehicle.

When replacing and having a “five-machine console”, the connection diagram is as follows:

Native console (central console) of the VAZ 2107, the connection principle is as follows:

The power cord is blue and red, paired, one part fits and powers the on-board clock.

It is also important to know that in addition to wires, the circuit includes:

The lighter itself;
A 10 amp fuse marked F 6, which is located in the mounting block.

Causes of malfunction

According to the regulations on the VAZ 2107 lighter, the coil should warm up until it turns red and bounce back within 20 seconds. If the time differs in any way, it can be adjusted by bending or prying the contacts of the lighter. If adjustment does not help, then replacing parts will help solve the problem.

Removing the cigarette lighter

First, disconnect the “total ground” again as always without exception, by removing the negative terminal from the battery;
Take the pliers and carefully tighten the metal rim of the lighter, being careful not to damage it.
After this, carefully pull out the cigarette lighter so as not to break the wires. If at this stage you notice broken wires, carefully solder them.

For many car enthusiasts, a lighter is an indispensable device, because a cigarette lighter in a car is needed not only as a cigarette lighter; in addition to using it for this purpose, connect it through the cigarette lighter socket to the power supply of a portable car refrigerator, compressor, TV, razor or coffee maker, mobile phone charger, etc. .

Removing the cigarette lighter of a VAZ 2107. Installing a Euro cigarette lighter

In the second disconnection of the electrical wires, unscrew the round cap behind the cigarette lighter.

In the fourth, use a thin flathead screwdriver to remove the cigarette lighter and light ring.

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

Remove the steering shaft cover by removing the five screws with a flathead screwdriver. We remove the dashboard plugs (the dashboard where the speedometer is located) and remove it by unscrewing the screws and disconnecting all the wires and the speedometer. If you have a water light control, remove the control holder, unscrew the nut and remove it from the dashboard.

Remove the bolts and remove the passenger side lower parcel shelf and glove box. Remove the handles from the heater control levers (to do this, bend a thin screwdriver or knife at the top and the middle handle at the bottom and top at the bottom) and remove the covers from the heater control levers. Remove the radio panel by unscrewing the mounting screws.

Remove the four screws securing the bottom of the center panel. And through the holes in the glove compartment and instrument panel, unscrew the four bolts securing the upper part of the central panel. After disconnecting the top insert on the center panel, pull the panel towards you and remove the plugs from the cigarette lighter socket.

We remove the car cigarette lighter as in the first method. Reassemble in reverse order: reinstall the lighter, replacing the housing with the bulb and tightening the rear round nut. Connect the plugs to the car cigarette lighter and proceed to install the center panel. Slide the center panel into place and tighten the four screws through the holes in the dash and dash to secure the center panel. Install the four screws that secure the lower center panel. Screw on the top center panel insert.

Install the radio panel by tightening the mounting bolts. Install the bolts and reinstall the lower

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.

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.

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.

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.
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.
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.
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.

Note to the owners of the Five, the electrical diagram of the VAZ 2105 and 21053

The VAZ 2105 electrical circuit diagram is a collection of all devices and equipment used in the car. Its performance largely affects the functionality of the entire car as a whole, so the Five car owner must be able to understand it. If necessary, this will allow you to understand the malfunctions and identify the breakdown in a timely manner.

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.

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.

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:

In addition to its intended use, the following can be connected to its socket:

The cigarette lighter consists of a socket (socket) and a head (cartridge)

The cartridge is a metal body with a plastic handle in the form of a button. There is a metal rod in the center of the socket that acts as a positive contact. The negative contact in the cigarette lighter is the housing. To prevent short circuits, the body and the rod are separated from each other by a layer of insulator. The contacts are connected by a nichrome spiral, which is a heating element and is located inside the cartridge. When current is applied to the coil, it heats up to a high temperature. When the temperature reaches a certain value, the thermal relay is triggered and the current supply is stopped.

The cigarette lighter is located on the instrument panel in a convenient place for the driver. The nest is made in the form of an oblong metal body, which acts as a mass. The central contact is connected to the battery positive. In addition, a backlight lamp is built into the cigarette lighter housing, which turns on together with the external lighting.

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.

Features of the procedure when replacing a short European cigarette lighter

One of the problems with the classic device is weak contacts. When driving on broken roads, the seats become loose, as a result of which the retaining ring can fly off, which can lead to a short circuit. Therefore, many owners decide to buy a short Euro cigarette lighter, also suitable for the VAZ 2107.

Its installation is carried out according to the diagram.

The disassembly procedure is similar to the previous procedures.
The diameter of the Euro cigarette lighter socket is slightly larger. Therefore, you should bore the old hole with a file to a suitable size.
Install the green part of the backlight.
We mount the landing socket.
You need to buy a standard three-pin connector at the store. The yellow wire is soldered to the yellow, the center green to the red, and the blue to the negative black.
Next, all that remains is to assemble the device according to the reverse diagram of disassembly and check its serviceability.

Malfunctions of the ignition coil of VAZ 2106

There are individual malfunctions of the ignition coil that lead to replacement of the product. These include external mechanical deformations of the product and breaks in the coil windings. A malfunction of the VAZ 2106 ignition coil is classified as a condition when the ignition coil heats up to a high temperature.

Slight heating of the product is the normal state of this part when the ignition is turned on and the distributor contacts are closed with a contact ignition system. If you doubt the functionality of this part of the ignition system, we recommend checking the coil for the resistance of both windings of the product.

The main causes of malfunctions of the VAZ 2107 cigarette lighter

The cigarette lighter of the VAZ 2107 quite often fails. This happens for various reasons.

Fuse blown

If the cigarette lighter is used as a power outlet to operate multiple high-power devices through a power strip, the cigarette lighter fuse, rated for a maximum current of 10 A, may blow. Due to the peculiarities of the VAZ 2107 electrical connection diagram, the clock and radio will stop working along with the cigarette lighter.

Poor contact or oxidation

Sometimes the cigarette lighter contacts or connectors become oxidized and the device stops working. In such a situation, they must be cleaned by first disconnecting the negative terminal from the battery. The latter will eliminate the possibility of a short circuit. In addition, often the connector of the device connected to the cigarette lighter does not fit into the socket tightly enough. Such unreliable contact can lead to short circuits, melting of contacts and failure of the cigarette lighter. The contacts may also melt when installing a fuse of a higher rating (for example, 15 A). In such cases, you can try to clean and resolder the contacts. If this does not lead to a positive result, the cigarette lighter will need to be replaced with a new one. The cost of a new device for the VAZ 2107 is about 150 rubles.

Burnt out filament element

Sometimes the cigarette lighter coil burns out. In this case, the device is replaced with a new one.

Broken electrical wiring

The cigarette lighter may stop working due to pinching or chafing of the wires, followed by broken contacts. You can diagnose this situation using a multimeter by testing the wiring of the cigarette lighter connection circuit.

After finding the damaged section of the wiring, it is replaced with a new one. Particular attention should be paid to the integrity of the wire insulation - this will reduce the likelihood of a short circuit and fire to a minimum.

Car cigarette lighter illumination

Sometimes a light bulb burns out. This occurs due to old age or a small short circuit. You need to diagnose the problem and then replace the backlight bulb with a new one.

Remove the wire from the battery.
We take out the metal cartridge.
Remove the central plastic cover.
Disconnect the power wires.
Unscrew the fixing nut.
Remove the housing along with the backlight bulb.
We replace the burnt out element with a new spare part.
We assemble everything according to the diagram in reverse order.

Replacing the cigarette lighter of a VAZ 2107 with a cigarette lighter from a VAZ 2114

VAZ 2107 owners sometimes change the standard cigarette lighter. Reasons for replacement are:

Most often they install a cigarette lighter from a VAZ 2114/15 - the so-called Euro-cigarette lighter, which is slightly shorter than the standard one. Installing it on a VAZ 2107 is quite simple. After dismantling the standard cigarette lighter, you will only need to slightly enlarge the hole in which it was fixed.

You can use sandpaper or a round file to widen the hole.

The device is installed in the following order:

Thus, any malfunction of the VAZ 2107 cigarette lighter can be eliminated independently. To do this, you only need a minimum set of plumbing tools and following the instructions of specialists. Installing a new cigarette lighter will also not cause much trouble for the owner of a VAZ 2107.
