Lada Granta cigarette lighter fuse does not work

I decided to check the tire pressure and pump it up a little. Why did I take a compressor (pump) from my dad’s car that runs from the cigarette lighter? Already knowing that the cigarette lighter was specific, I understood that the plug might have to be held. I walked around 2 wheels, held the plug with one hand, and turned the pump on and off with the other. Then, no matter how I twist the plug, it’s no use. Well, I thought that was it, the cigarette lighter had already burned out. I looked at the plug, took it apart, the fuse is fine. I plugged it in, gave the pump to my dad and pumped it up at a gas station.

The next day I realized that the signal was not working

.
Since I had already read a little, I realized that the problem was most likely in the fuse. I opened it, looked, and the F20 at 15A
.

I went to Auto49, bought this F20 and a set of spare ones. Replaced it, the signal worked.

The most interesting thing for me is that, in theory, this fuse is responsible for the trunk lock, the box, and the diagnostic connector in addition to the cigarette lighter and the signal. I don’t know how everything else was listed, but the trunk lock definitely worked when it burned out.

To prevent failure of electrical equipment and devices, the car's electrical wiring contains an element called the Grant Liftback fuse box.

If it is installed incorrectly, then a normal short circuit in any of the electrical components will lead to a fire in the wiring, which can cause internal damage and even spontaneous combustion of the machine. Therefore, the installation of this element requires a special approach and caution.

Connection diagram

Connecting the cigarette lighter is not difficult. The device is connected to the on-board network with only three wires.

1. Black wire - the ground of the car is connected to the cigarette lighter body.
2. Red wire – power is attached to a terminal at the end of the housing. This threaded clamp also serves as a fastening for the heater retainer, so power is supplied to it as well.
3. Yellow wire – power supply for instrument lighting is connected to the lamp socket. Ground, which is supplied through its contact with the cigarette lighter body.

Design and operation

The cigarette lighter in a car consists of a chrome-plated metal body, a heating element with a coil of high resistivity material (nichrome or similar), a plastic push-button handle, and a coil spring inside the housing. The cigarette lighter socket is a steel cup with a bimetallic heater retainer on the end wall of the housing inside. The common wire of the car's electrical equipment (ground) is connected to the body of the cigarette lighter socket, and the power (+) is connected to the heater retainer. To illuminate the cigarette lighter socket in low light conditions, a light guide made of transparent greenish plastic is installed on the body, onto which a socket with a small light bulb is attached. One of its contacts is connected to the socket body, and the other to the wire that supplies power to the instrument lighting.

The cigarette lighter works as follows. One end of the heater spiral inserted into the socket is in contact with ground through the cigarette lighter body. When you press the handle-button, the heater is fixed with a bimetallic latch, to which at this moment the other end of the spiral is connected. The current flowing through the nichrome wire heats it up. This also heats up the bimetallic clamp, which, when a certain temperature is reached, straightens and ceases to hold the heater. Then the cigarette lighter button, under the action of a spring, breaks the electrical circuit of the heater with a characteristic click and jumps out.

Electrical appliance protection

The electrical wiring is protected from a short circuit in the cigarette lighter by a fuse link in the fuse box. It is denoted by CIG, cigar, or a pictogram depicting a smoking cigarette. The rating of this fuse is most often 15 A.

The device is protected from fire by a low-melting metal washer installed under the nut securing the power terminal. The principle of operation of this protection is as follows. When the nichrome spiral is overheated for a long time, the end of the socket body heats up to the melting point of the protective washer. Melting, the washer flows down and connects the power terminal to the body of the device connected to the common wire of the electrical equipment. As a result of this short circuit, the fuse-link burns out, the cigarette lighter is de-energized, and heating stops.

Common reasons for refusal

The reason why your cigarette lighter is not working may be due to the following faults:

• The fuse has blown.
• Broken filament coil.
• Fire protection activated. With this malfunction, the new fuse fails during installation. Triggering of fire protection often occurs due to accidental pressing and prolonged holding of the cigarette lighter button. What can happen, for example, when you try to reach an object that has fallen on the floor and rolled under the seat.
• Corrosion of power terminals and cigarette lighter ground.

How to properly remove the cigarette lighter on a Lada Granta

The presented photo report will show how to remove the cigarette lighter on a Lada Granta in order to replace or repair it. You will also find out why the cigarette lighter fails.

Why does the cigarette lighter on the Lada Grant fail?

One of the main reasons for the failure of the Lada Grant's cigarette lighter is a short circuit, which can occur as a result of a malfunction in the vehicle's on-board network or due to wear of internal elements. Also, removing the cigarette lighter on a Grant is also necessary to replace a burnt-out diode (light bulb) for lighting the socket.

Which cigarette lighter to buy

If you are unable to find the original Granta cigarette lighter, then an excellent alternative would be a spare part manufactured by catalog number DA5100F0109

How to remove the cigarette lighter on a Grant

First of all, as when working with any component of a car's electrical equipment, you need to turn off the power to the battery and only then begin to remove the cigarette lighter. Carefully bend the edges so that the plastic protrusions do not interfere, and release the metal cylinder. Then you need to remove the center console of the torpedo.

Video of removing the Granta center console

After that, use a screwdriver to press the upper latch on the green plastic case and try to pull the base of the cigarette lighter out a little. Now you need to try to disconnect the connector and completely pull out the cigarette lighter Grants.

Design and purpose of the cigarette lighter

The device is designed simply:

• metal cartridge with a nichrome spiral;
• button;
• plastic handle.

There is a special socket on the dashboard into which the cigarette lighter is inserted. When you press the handle, the device connects to the vehicle's on-board network. A current passes through the nichrome spiral and it heats up. As soon as the temperature reaches its maximum, the thermostat is activated, a click occurs, and the cigarette lighter returns to its original position.

In the first car models, the device was used directly for lighting cigarettes, but with the development of technology its use has expanded significantly. Currently, all external electronic devices are connected through it: vacuum cleaners, navigators, chargers, radar detectors, mobile phones.

Typical faults

The reasons why the cigarette lighter does not work can be different. One of them is a blown fuse. It may burn out due to connected devices, such as a compressor or splitter. To eliminate the problem, you need to open the mounting block, remove the burnt fuse and insert a new one. A regular 15 or 20 Amp fuse will do.

The second no less popular malfunction is the antenna contacts that are bent inside the device. If you use the charger frequently, the metal tendrils will unbend over time. To return the device to functionality, the antennae should be slightly bent using a flat-head screwdriver (video author: Andrei Che).

Repair and replacement instructions

If the reason is not the fuse and the antenna, then the device may not work. In this case, it needs to be replaced. Replacement is complicated by dismantling the plastic floor tunnel.

The replacement procedure for the Lada Kalan and Lada Granta Liftback is similar and consists of a sequence of actions:

1. First of all, you need to remove the battery terminal.
2. Then unscrew the three mounting bolts that hold the plastic handbrake lining.
3. Next you need to unscrew the handbrake switch.
4. At the back of the tunnel there is a self-tapping screw, which we unscrew in the next step.
5. Then we unscrew the fastenings of the floor tunnel from the side.
6. Next, remove the cover from the gear shift knob.
7. Now you can lift the tunnel and begin replacing the cigarette lighter.
8. Before replacing, you must disconnect the power.
9. Next, press the latches that hold the cigarette lighter, and you can remove it.
10. We insert a new part and perform the reverse assembly steps.

Replacing a broken cigarette lighter is simple; any car enthusiast can handle this procedure.

This video describes how to replace the fuse of a 12-volt outlet on a Lada Granta (video author - remgar).

Cigarette lighter repair

To successfully troubleshoot the problem, you first need to determine why the cigarette lighter does not work. To do this, remove it from the socket and use a test light to check whether there is electrical power on the heater latch and whether there is ground on the body. It is better to do this with a control unit, because, unlike a voltmeter, it consumes current. Therefore, in the case of oxidized contacts, it will glow only at full intensity or will not light up at all. The voltmeter readings in this case will not differ from those taken from a working device, since in the absence of current there will be no voltage drop across the resistances of the oxidized contacts. Below we describe several variants of the results of this test.

Features of the first mounting block

Once you know where the blocks are, you can talk about their features. Another significant difference between the Lada Grant and representatives of previous generations is its numerical composition. Now it is equal to 32 units. For a detailed understanding, you will need to carefully familiarize yourself with the block diagram. For example, fuse F1 has a function to protect the circuits of such current collectors:

• ignition coils;
• nozzles;
• motor and fan control unit.

Element F2 is responsible for the safety of the electrical power window mechanism circuits.

F3 and F4 respectively “monitor” the safety of circuits belonging to:

• hazard warning lights and windshield wipers;
• airbag.

Elements F9 and F10 are “entrusted” with controlling the wiring to the side lights.

It is important to remember that each safety element has a current limit that it can withstand.

• F8, “standing guard” of the rear window heating circuit, is designed for a maximum of 30 Amps;
• F6, which controls the operation of the reversing light, can only withstand 7.5 A.

It is easy to guess that these values ​​of this parameter are directly dependent on the required electrical consumption of a particular pantograph.

To familiarize yourself in detail with the circuits and the fuses that protect them, it is recommended to resort to the diagram (Fig. 3).

Replacing the cigarette lighter

How to install a new cigarette lighter in a car if the old one is burned out and cannot be repaired? Let's look at the example of a VAZ 2108 car with a low instrument panel (old model).

• Buy a new car lighter.
• Using a flathead screwdriver, remove the plastic ends from the air damper control levers.
• Remove the screws securing the air damper control bracket.
• Pull it towards you and remove the knob from the fan speed control.
• Remove the screws securing the center console to the instrument panel (2 pieces on each side). Pull the console towards you and disconnect its connectors from the wiring harness.
• Remove the console.
• Using two fingers, press the sides of the bracket holding the backlight socket and remove it from the light guide of the socket.
• Press the plastic socket clamps with your fingers or a screwdriver and remove the assembly body from the console hole.
• Insert a new socket in place of the old one.
• Install the backlight assembly onto the light guide. Make sure that there is contact between the backlight bracket and the body.
• Connect the console connectors to the wiring.
• Check if the buttons, regulator and the unit you replaced are working.
• Put the console back in place.
• Attach the damper control bracket to it.
• Secure the console with self-tapping screws.
• Place the handles on the levers and the regulator shaft.

The replacement has been made.

If the cigarette lighter does not work, there may be several reasons for the problem. Read below about why the cigarette lighter does not work, how to remove it and how to change the device.

Where is the cigarette lighter fuse located?

A common reason why a device stops working is a burnt-out protective element. The current strength in the circuit itself is precisely fixed, and its value should not exceed 15 amperes. When connecting powerful devices or a short circuit, the fuse blows, causing the VAZ cigarette lighter to stop working.

The fact that this particular element needs to be changed will be indicated by indirect reasons. The fuse is responsible for:

• sound signal;
• trunk lock;
• immobilizer, this means that if it fails, the owner will not start the car.

To change a non-working cigarette lighter fuse, you need to get to the mounting block. It is located in the cabin under the decorative panel, to the left of the steering column. The cigarette lighter fuse is held in place by five plastic clips.

1. We disconnect them and get to the rear space.
2. We take out the plug that attaches to the luggage compartment opening button. Now you can completely remove the panel.
3. We gain access to the mounting block, where tweezers are also located, allowing you to quickly pull out the protective elements.

The Lada Granta model has two versions of the fuse box - old and new. If the car is from the first years of production, then you will need to replace the element number F20. The mounting block diagram of newer models of the cigarette lighter fuse differs from its predecessor. Here you should change element F27. The fuse must be rated 15 amps. When installing a protective element with high resistance, problems may arise. If the current in the circuit exceeds the maximum permissible value, the cables will melt, which can result in a short circuit or fire in the wiring and a blown fuse.

Reasons for failure of the cigarette lighter on the Lada Grant

A malfunction can occur due to various circumstances. Among the most common reasons why the cigarette lighter on a Lada Granta car does not work are:

1. Blown fuse. This happens due to connecting a large number of devices to the connector. The total power of connected devices should not exceed 180 Watts (15*12=180). Otherwise the cigarette lighter fuse will blow. AvtoVAZ models have different protective elements (Granta - F20/F27, Kalina - F18, Priora - F13). The fuse rating must correspond to the value specified by the manufacturer.
2. Poor contact. Over time, oxides or rust develop on the tendrils of the metal cartridge, resulting in a poor connection. To correct the situation, it is enough to remove the cigarette lighter, inspect the condition of its contacts, and treat them with a file to remove rust or oxides.
3. Broken wiring. Three wires come to the device, the soldering of which disappears over time. To identify the malfunction, you will need a multitester.

In the latter case, you need to call three contacts.

1. Red cable. Plus, responsible for heating the element. Comes to the battery through a 15 amp fuse.
2. Yellow. Plus, it is responsible for the cigarette lighter light bulb.
3. Black. Minus coming to the car body.

Other causes of cigarette lighter failure.

1. Burnt out metal spiral. There is a nichrome spiral inside the cigarette lighter, which can burn out and trigger the fuse. If there is voltage in the connector and current flows to the contacts, but heating does not occur, then the reason lies here. It is treated by replacing the cigarette lighter with a new part.
2. Failed backlight lamp. There is a light filter around the seat. Over time, the light bulb may burn out. The malfunction is eliminated by installing a working element.

The principle of operation of the cigarette lighter

A cigarette lighter is a special heating element that is often connected to the car battery. If this is so, then the device will work even if the ignition switch is simply turned on. In addition to its direct purpose, the plug is used as a charger for a mobile phone and other gadgets. Due to the fact that a splitter is often connected to it, this ensures simultaneous charging of several devices at once, including the DVR.

Video “Fixture Repair”

Cigarette lighter repair is covered in detail in the video from the author Alexander Zagorny.

Poor performance of any piece of electrical equipment in a car should cause some concern and careful examination of all parts of this important unit in your car. If the cigarette lighter in your car does not work, you need to check the main wires, connections and equipment that are associated with this element. Often the cause of such a breakdown is the direct combustion of the cigarette lighter head itself.

This element of the automotive electrical system today is used not so much for lighting cigarettes, but for charging phones, connecting GPS navigators, recorders and other devices. The cigarette lighter is a full-fledged car socket if you have an adapter to connect your devices. Therefore, its normal operation must be ensured.

Power fuses

An additional block of power modules is located in the engine compartment, under the hood, behind the battery and expansion tank. It accommodates the following five modules:

• F (F-1) / 50A: electric power steering (EPS). Connected to fuse F32;
• F (F-2) / 30A: stove heater cooler (in the cabin);
• F (F-3) / 60A: generator;
• F (F-4) / 60A: generator contact board;
• F (F-5) / 30A: low beam. Connected to fuses F12, F13.

The main causes of cigarette lighter failure and their solutions

If the immediate first function of this device is important to you, try replacing the cigarette lighter head. This is the first and simplest action that should be performed in this situation. With intensive use, the heating coil burns out and stops performing its tasks. But this process should be carried out carefully - buy only the head that fits your car model.

If this process does not help, you should look for the cause of the problem directly in the electrical network that connects the cigarette lighter. To do this, you need to check all connections and make sure there are no burnt wires or connections. The main factors that are worth checking in this aspect are the following:

• the functionality of the fuse that is responsible for the operation of the cigarette lighter;
• integrity of all electrical connections of the equipment itself, wires on the cigarette lighter body;
• absence of carbon deposits and foreign particles in the cigarette lighter socket and on the contacts;
• serviceability of the plug when connecting certain devices to the cigarette lighter;
• absence of overloads on this unit during its operation.

These tests will help you identify the faulty unit. The easiest check is related to the fuse box. Check your car's owner's manual to see which fuse controls the cigarette lighter. Then replace it with a known working element of the electrical system and check the operation of the device.

To check for oxidation of contacts or the presence of foreign objects in the socket, it is enough to visually examine the equipment, and if there are blockages, remove them using non-metallic objects. In all other cases, you will have to remove the cigarette lighter from its installation location and check the electrical connections.

Tips for motorists

The main problems associated with the failure of the cigarette lighter on a Lada Granta passenger car are that most inexperienced drivers begin to use the cigarette lighter socket not for its intended purpose, but as an outlet for connecting various additional devices that require on-board power supply of 12 volts. At the same time, these drivers do not have basic knowledge about the safe use of the cigarette lighter socket.

Firstly, Lada Granta drivers should know that the electrical circuit of the cigarette lighter, as well as the sound alarm set, trunk lock and gearbox is protected by fuse F20 (15A, blue), located in the mounting block in the front panel of the cabin to the left of the steering column. This means that the total power of consumers powered through this fuse should not exceed 180 watts (15A x 12V = 180W).

Therefore, the driver should ask what the power consumption of the device he wants to connect to the cigarette lighter socket is. If this power is more than 180 watts (for example, a compressor for inflating tires), then when it is connected to the cigarette lighter socket, the current in the circuit will be more than 15 amperes and fuse F20 will blow. Instead of a blown fuse, it is impossible to install another one, but one designed for a higher current strength, as this can lead to strong heating of the wires, melting of the insulation and a fire.

Secondly, Lada Granta drivers need to know that in the automotive industry there is no single standard for the size of the cigarette lighter socket, either in diameter or in depth. Therefore, the plugs of additional devices will also differ in size. If your accessory that you want to connect to the cigarette lighter socket has a plug that is slightly smaller in diameter, this will usually result in a short circuit in the cigarette lighter socket and blown fuse F20.

This is due to the design of the cigarette lighter socket, where the positive and negative contacts in one place are located very close to each other and an incorrectly inserted plug of a smaller diameter, standing askew in the socket with its side contact, closes the contacts of the cigarette lighter socket, resulting in a short circuit. Therefore, before purchasing an additional device, you need to make sure that its plug fits tightly into the cigarette lighter socket.

The device has become popular in recent years. Now even non-smoking car owners use the cigarette lighter. Indeed, in addition to its nominal purpose, the device performs a lot of functions. For example, various devices are connected to the cigarette lighter socket:

• power bank for mobile phones or tablets;
• charging for laptop and electronics;
• DVR;
• navigation system;
• electric pump that inflates the wheels.

When used correctly, the device works for a long time, but due to certain features it may fail. Read on to find out why the breakdown occurs, how to recognize the cause of the malfunction, replace the cigarette lighter or repair it on the Lada Granta model.

Dismantling and repairing the electrical connection of the cigarette lighter

If none of the above works, you will have to remove the cigarette lighter socket itself and look at the integrity of the electrical connections. This task must be performed with the utmost care so as not to damage the delicate contacts and also not to spoil the visual appearance of the socket. Often this item is chrome plated, making it difficult to remove.

Each car has its own characteristics of disassembling this unit. If you can reach the back side of the panel and push the socket from the inside, this dismantling option will be the easiest. Otherwise you will have to do the following:

• find a tool with rubberized tips - these can be special pliers;
• if you don’t have such a tool, use regular pliers, but place a soft cloth under the tool;
• pull the different edges of the cigarette lighter one by one and slowly pull it out of the installation location;
• you should not put too much effort, because you can damage the plastic elements of the panel and ruin the appearance of the metal;
• After dismantling, provide a high stand under the cigarette lighter socket so that it does not hang on thin wires.

This will help you remove the device socket safely and without damage and gain direct access to the wires. If you have reached this stage, then most likely you will find one sealed or burnt wire on the case. It needs to be soldered in place to ensure proper operation of the equipment.

If you find a burnt wire, you will have to work hard. In such a situation, the easiest way out is to contact automotive electrical specialists and get the necessary services from them. This will help eliminate the hassle of digging through electrical wiring and will give you the desired results of your cigarette lighter working well.

If you are missing one cigarette lighter, you can install another socket, as the hero of the following video did:

About fuses in Grant

Sometimes failures of elements in the vehicle's electrical on-board network occur. For domestic models, this malfunction is much more relevant in comparison with foreign analogues. The causes of damage to the electrical network can be very different. Among the most common factors causing blackouts is the usual overvoltage. Most likely, after this phenomenon, the owner will need to replace the corresponding fuse. A painfully familiar model, the Lada Granta, can serve as an example.

In the car we are considering, the lion's share of electrical circuits and current collectors is protected by fuses. We should not forget about the lack of protection for three nodes:

• battery charging circuits;
• generator electrical circuit;
• starter.

A high current flows through these objects, which is necessary for their normal functioning.

We also draw attention to the absence of the need for the ignition to be turned on for such systems as:

• alarm;
• cigarette lighter socket;
• radio;
• external optical lighting devices, etc.

The Lada Granta has two separate blocks. The developers placed the first one in the salon. His area of ​​responsibility is most of the circuits and pantographs located inside the cabin, where you can find the cigarette lighter fuse. The second safety module is located in the engine compartment, where you will find the fuel pump fuse. It is designed to protect power circuits from overloads and short circuits. Thanks to the visual diagram, it is not difficult to understand where all the necessary fuses are located.

Let's sum it up

All processes for restoring the operation of the cigarette lighter socket are performed independently. Only if one of the wires connecting the equipment is burned out, you will have to contact specialists with a request to replace this wire. In all other situations, it is enough to use your own strength and quickly fix the problem using a soldering iron or simply replacing the fuse or cigarette lighter head.

If your car has non-working electrical equipment, it is worth finding out the causes of the breakdown and eliminating them. This will increase the operating comfort of the vehicle and make the machine safe to use. Have you ever had problems with your cigarette lighter?
