Replacing the cigarette lighter and its illumination lamp (for use on the Lada Priora model)

What is a cigarette lighter for?

A cigarette lighter can be used not only for lighting cigarettes, but also for more useful actions. You can connect a lot of different equipment to the cigarette lighter socket, which, of course, has a voltage of no higher than 12V.

What can be connected to the cigarette lighter:

• Charger for phone, laptop or tablet;
• Automobile compressor;
• DVR, radar detector;
• Car refrigerator;
• Car vacuum cleaner, etc.;

Currently, there are a huge number of car accessories powered by a cigarette lighter; such a connection has made it possible to use these devices with ease.

What devices can be connected to the cigarette lighter?

Knowing the current rating for which the Prior's cigarette lighter fuse is designed, you can calculate what power devices can be used. To do this, we multiply the current strength of 15 A by the rated voltage in the cigarette lighter - 12 V.

We find that the power of the connected devices should not exceed 180 W. And the list of devices is very wide, because technological progress does not stand still, making the life of the driver and his passengers much more comfortable. Here are some of them:

• Compressor; • Air purifier and ionizer; • Electric kettle or boiler; • Fridge; • Massage cape or pillow; • Navigator, video recorder, etc.; • Heater on the seat; • Lamp or lantern; • Fan; • Vacuum cleaner; • Splitter.

New devices appear every year. You must be very careful when connecting them to the cigarette lighter. Heavy load can lead to short circuit and fire.

How does a cigarette lighter work?

The cigarette lighter is made in the form of a cylinder into which the heating element or plug of a car accessory is placed. The power supply in it has a constant voltage of 12V, which is protected by a fuse. The cigarette lighter has “+” and “-” through which current flows when a load is connected. The backlight is also powered from the cigarette lighter, which also operates at 12V.

The standard cigarette lighter socket has the form of a cylinder, inside of which there is a nichrome filament, which subsequently heats up to a high temperature.

Possible causes of failure

There are quite a few reasons why the cigarette lighter on a Priora may not work, but most often they are of the same type and are associated with improper use of this part or due to its aging.

• Contamination of the contacts inside the cigarette lighter, which makes it impossible to conduct current through them. This problem occurs quite often if the cigarette lighter is used as intended. Remaining ash gets inside the cigarette lighter and contaminates it.
• The cigarette lighter connector, which is connected to it from below, is also susceptible to damage. When using powerful accessories, the contacts may burn.
• The cigarette lighter fuse is one of the most common problems with a non-working cigarette lighter. Fuse blowing occurs due to a possible short circuit or the use of powerful car accessories.
• A malfunction of the cigarette lighter illumination does not lead to its failure, but still, when something in the car does not work, it is not good and requires repair.

The problems that happen with the cigarette lighter are clear, now you need to figure out how to solve them and fix the cigarette lighter.

Which fuse is responsible for the operation of the cigarette lighter in Priora

Knowing where the cigarette lighter fuse is located on the Priora, you can replace it without any problems. Service in auto repair shops is now quite expensive, so let’s figure out how you can do it yourself.

The most important condition is that you cannot install any home-made devices, such as, for example, wire or a paper clip, instead of the fuse. In addition, it is better to use domestically produced protective elements and not buy Chinese analogues, as they are of low quality. None of this is safe and can even lead to a fire.

Replacing the Priora cigarette lighter fuse is not very difficult. To do this, there is no need to dismantle its seat or the block itself. It is enough to simply replace the faulty element with a new one. However, you still need to understand the algorithm, as there are some peculiarities.

Removing the cigarette lighter

To diagnose the Priora cigarette lighter, it must be dismantled. Removal must be done with the fuse removed, so as not to cause an accidental short circuit during operation. We remove fuse F13 from the mounting block and get to work.

• Insert a small flat-head screwdriver into the hole on the cigarette lighter and lightly press on the plastic retainer, as shown in the picture. Then turn the metal part of the cigarette lighter counterclockwise.

• We take out the metal part up and disconnect the connector.

• Use your finger to pry up the green outline of the cigarette lighter illumination and remove it as shown in the picture.

• We perform assembly in reverse order.

Additional mounting block Priora

• F1 (15 A) – main relay and starter interlock circuit fuse;
• F2 (7.5 A) – fuse for the power supply circuit of the ECU (controller);
• F3 (15 A) – Priora fuel pump fuse;
• K1 – main relay;
• K2 is the place where the Priora fuel pump relay is located.

Attention! The relay and fuse diagram may differ depending on the configuration and production date of the vehicle. Current diagrams of the mounting block are presented in the operating manual for the date of manufacture of the vehicle (download from

site).

Let us remind you that on our website you can find detailed instructions for repairing the Lada Priora with your own hands.

The cigarette lighter light does not light up

This reason occurs due to the burnout of the backlight lamp or its poor contact with the cigarette lighter body. To check, you need to remove the cigarette lighter and inspect the lamp. If the lamp is intact and has no signs of damage, most likely it does not work due to poor contact.

To ensure reliable contact, it is necessary to bend two contacts on the lamp socket and clean them with sandpaper. It is also a good idea to clean off carbon deposits, if there is any, on the outside of the cigarette lighter, where the lamp contacts come into contact with the cigarette lighter body.

Greetings. We will replace the cigarette lighter for the Lada Priora.

We will replace the cigarette lighter assembly and also replace the backlight bulb. To replace it, the floor tunnel is usually removed, we will show you how to do without it.

• VAZ 2110: replacing the cigarette lighter yourself

Tools:

• small flathead screwdriver

Work must be performed with the battery disconnected.

Serial number and part numbers

Before you begin repairing the cigarette lighter and disassembling the central tunnel, you need to buy a suitable spare part. There are different device options for the Lada Priora on sale, both original and not. Cigarette lighters from the AvtoVAZ factory have article number 21230-3725010-00.

When purchasing, you need to pay attention to the cost of the spare part. A cigarette lighter price that is too low indicates the use of low-quality materials. Such a part may burn out within several weeks after replacement. In addition, the item must be well packaged and have a certificate of conformity.

Cigarette lighter

The domestic auto industry is in no hurry to replace the cigarette lighter with sockets, so all our cars are equipped with its classic version. Lada Priora is no exception. Here it is located in a place of honor - the central floor tunnel, next to the parking brake handle.

This arrangement of the device was not chosen by chance. It is always in sight, you can reach it with your right hand without bending, it does not interfere, and it is impossible for your pant leg to get caught on it. For greater convenience, it is also equipped with a backlight, which makes it easier to find in the dark.

It is worth noting that the Priora’s cigarette lighter differs from previous models not only in location, but also in configuration: its socket is somewhat smaller than that of other VAZs.

Design and operating principle

The Priora's cigarette lighter is no different from the cigarette lighters of other cars. Structurally, it consists of a socket (a hollow metal cylinder) and a metal cartridge with a nichrome spiral inside.

The cartridge is equipped with a plastic button, when pressed, the “plus” is connected to ground through the spiral. The principle of heating the coil here is exactly the same as in an electric stove or iron, but unlike the latter, the Priora cigarette lighter does not have a thermal relay. Its task is performed by bimetallic “ears” inside the cartridge, which, when heated, expand, and the spring ejects the cartridge, setting it to its initial position.

Malfunctions

Like any other electromechanical device, the Priora cigarette lighter tends to break. Sometimes this can be caused by design defects, sometimes by malfunctions in the machine's on-board circuit, and sometimes by the fault of the user himself. Common cigarette lighter malfunctions include:

• sinking of those same bimetallic “ears”;
• burnout of the spiral;
• broken contact in the connector;
• fuse blown.

Malfunctions can also include the burnout of a backlight lamp, however, this is more related to a decrease in the level of comfort than to serious breakdowns. In addition, it does not in any way affect the operation of the device itself and can be easily eliminated by replacing the lamp.

The sinking of the lugs is characterized by the lack of fixation of the cartridge in the pressed position. It can be caused either by the low quality of the metal from which they are made, i.e. defect, or high intensity or long period of use of the cigarette lighter.

The problem is solved by bending the “ears” inward using a thin screwdriver, naturally after de-energizing the on-board circuit. If after a short period of use the problem occurs again, it is better to replace the cigarette lighter.

When the spiral burns out, the cartridge is fixed when pressed, but does not heat up. The fault is diagnosed by ringing it using a car tester. It is not recommended to restore the spiral, as this may lead to a decrease in its resistance, which will make unwanted adjustments to the operation of the on-board circuit. In this case, the cigarette lighter also needs to be replaced.

Contact failure can be easily determined by removing the tunnel lining and checking the condition of the connector. This malfunction is not critical and can be fixed independently in a few minutes.

But as for the fuse, it makes sense to consider this malfunction separately, since its malfunction is most often caused by the human factor.

Replacing the cigarette lighter and its backlight

The cigarette lighter itself is not difficult to replace, you just need to pry the antenna inside the cigarette lighter with a screwdriver and pull out the inner part, and then we take out the plastic itself with the lamp, prying it with a thin screwdriver on both sides and pressing on the antenna. In principle, if you have already purchased a new cigarette lighter, you can simply look at how it works and everything will become clear.

DIY Lada Priora instrument panel pinout: diagram

The dashboard contains the following parts, without which the car would not function:

• external lighting controller;
• switch for turning and lighting headlights;
• signal regulator;
• instrument cluster;
• wiper regulator.

When is pinout required (device chips) and how to do it

All car parts fail sooner or later. There are times when they need to not only be repaired, but replaced. The instrument panel may also break, causing it to be removed and a new one installed in its place. This work is easy to do with your own hands if you have at least the slightest knowledge of mechanics. If you are well versed in your Priora (sedan), then you need to perform the pinout in this way:

1. First, the dial hands are removed using a regular knife.
2. Next, the gasket in the speedometer is scraped out to replace the backlight.
3. If there is no need to change the sensors, you can simply remove them and clean them.

Very often, motorists cover the panel with a special LED strip to achieve even lighting. You can also use CMD diodes, which can be easily fused into glass with a soldering iron. To do this, you need to disassemble the dial and solder diodes directly under the base of the hands.

If you understand the purpose of all the contacts, and also know the purpose of a particular connector on the panel, then you can easily do the pinout yourself. The main thing is to carry out everything strictly according to the instructions so that the connection is successful and the panel continues to function efficiently. If you know which is better to install a tidy: with a canbus or a regular one, then it’s better to ask professionals who understand this. If you have no experience in such work, and you do not understand the purpose of certain wires, then the technical service will help you improve the operation of the instrument panel. Of course, you will have to pay for this, but you will not waste your time, and the work will be done efficiently.

Fuse

To ensure the safe operation of the cigarette lighter and devices connected to it, its electrical circuit is protected by a fuse. It is located in the mounting block located in the car interior under the dashboard. In the diagrams it is marked F-13 , and is designed for a maximum current of 15 A. Its body is usually blue.

Why does a fuse blow?

The cigarette lighter fuse in a Priora may blow out due to:

• connecting to the socket of devices whose plug is structurally smaller than the socket;
• discrepancies between the calculated current values ​​of the cigarette lighter circuit and the connected device;
• malfunctions of connected devices.

The diameter of the Priora cigarette lighter socket is 21 mm, and the diameter of the plugs of some electronic or electrical devices powered from the cigarette lighter is 18-20 mm. In other words, such a plug will dangle in the socket, and loosely pressed contacts will spark.

Sparking leads to charring of contacts and increased load on the circuit. As a result, the least that awaits us is replacing the blown fuse. The same thing will happen if you insert the plug into the socket incorrectly (at the wrong angle). This, by the way, is the most common reason why the cigarette lighter fuse blows.

Another “popular” reason is the difference in calculated currents. As already mentioned, the maximum fuse current is 15 A , and if you connect, for example, a compressor that consumes a current of 20 A to the cigarette lighter, it is no wonder that the fuse will burn out. Long-term operation of the same compressor, vacuum cleaner, refrigerator, or electric kettle can also lead to this.

Most modern electronic devices designed to operate from a cigarette lighter have their own fuse located in the plug. It allows you to protect the device itself from possible interruptions in the machine’s network, as well as the network from gadget malfunctions. But, if the device is faulty (for example, there is a short circuit) and is not equipped with a fuse, there is a reverse risk for the on-board circuit.

How to replace

1. Open the cover of the mounting block by turning the 3 plastic latches half a turn and remove it.
2. We find the fuse in the socket marked F-13 and pull it out of the socket. At the same time, we verify that it is not working visually or using a tester.
3. We install a new fuse in its place.
4. Install the lid and close it.
5. We check the results of our work.

To prevent problems with fuses from catching you by surprise, it is advisable to have a spare set of them in the glove compartment. This applies not only to the cigarette lighter, but also to other devices that are most susceptible to overload. Buying spare fuses won't impact your budget at all, but will give you confidence on the road. The cost of one fuse is about 5-7 rubles, and a set of 10 pieces is 40-60 rubles.

And, of course, in no case should you use various kinds of “bugs” instead of a fuse, be it a coin, a piece of wire, or your wife’s hairpin. Their use changes the parameters of the electrical circuit, and its overload may adversely affect the operation of any system that uses electricity.

In addition, the use of a jumper is fraught with the occurrence of a short circuit not in the cigarette lighter circuit, but in the car circuit. The result of this can be anything, including fire.

Replacing the cigarette lighter lamp on a Priora

Also, using a thin screwdriver, pry up the green plastic insert and carefully remove it from the hole in the floor tunnel.

As a result, we get the following picture.

To remove and change the backlight bulb, you just need to remove the black cover, and under it there is already the lamp itself, inserted together with the “socket” into the cigarette lighter housing. And to get it out of there, just pry it slightly with a screwdriver so that the latch does not interfere with removal.

The light bulb itself is also easy to change - just slightly pull it to the side, removing it from the “socket”.

Installation occurs in the reverse order of removal and no difficulties should arise as a result of this repair. If someone found the photo report not entirely clear and legible, then everything will be presented below in a more convenient form.

Dismantling on VAZ-2112

The cigarette lighter is located next to the ashtray. We don’t smoke and we don’t recommend it, so instead of an ashtray we have a “coin holder”!

The cigarette lighter housing is fixed to the tunnel lining. This trim needs to be removed. The trim near the passenger's feet is missing, and now we need to remove the same trim on the left (near the driver). Also use a screwdriver to pry up the plastic under the handbrake and remove the decorative plate (see photo).

First dismantling operation

Use the same flat screwdriver to pry off the cover on the gearshift knob. The cover is removed.

How to remove a tunnel

1. Unscrew the screw under the gearbox cover;

This part presses the trim to the body
