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

However, there is one nuance that the manufacturer did not mention in the instructions. The fact is that without dismantling the seats, the tunnel cover cannot be removed. Therefore, the seats are removed and four bolts are unscrewed. The first is to disconnect the trunk opening button chip, the second is to disconnect the cigarette lighter itself, slightly lifting the panel. By pressing the latches, remove the glass, replace it with a new one and reassemble in the reverse order.

How to remove and install the cigarette lighter on a Lada Priora yourself

Even non-smoking car drivers regularly use this device. Through it, charging elements and electronic gadgets are connected. Therefore, if the cigarette lighter fails, the car owner faces a number of inconveniences.

You can replace the part yourself. You can learn about the reasons for the failure, how to independently replace the cigarette lighter on a Priora and select a spare part from the article.

Reasons why the cigarette lighter does not work on Lada Priora

Over time, the unit may break and require repair. Why does the part fail? Among the common reasons why the Lada Priora cigarette lighter does not work.

1. Burnt out heating element. If you often have to connect high-voltage devices to the connector, such as a wheel compressor, the element itself can quickly fail and the fuse will trip.
2. Light bulb broken. There is a light around the hole that may stop working.
3. Oxidation or poor contact of the cigarette lighter. Over time, contact may be lost between the antennae of the part and the socket itself, as a result of which the element fails. To check this, you need to remove the fuse and then inspect it for oxides. Additionally, you should tighten the fastening antennae. The fuse is put in place.
4. The cigarette lighter connection wires have fallen off. Refers to “age-related diseases”. For inspection, you will need to remove the VAZ Priora cigarette lighter from its socket without touching the fuse. In the event of a malfunction, it is necessary to solder the fallen wires.
5. Inept tuning is also a cause of failure. Some owners buy low-quality splitters and load them to full capacity. This leads to increased load on the fuses. Promotes accelerated wear of the generator.
6. Blown fuse. A breakdown may occur due to a short circuit. To identify this fuse malfunction, you should connect the lamp to the connector. Then turn on the ignition. If it does not light up, then the reason is the fuse. The protective element needs to be replaced.

Connection diagram and node fuse

If the last problem occurs, you need to get to the shield located behind the front panel. Next, remove the plastic cover, gaining access to the fuse box itself. It is necessary to change the element numbered F13 - it is responsible for the cigarette lighter circuit.

Before doing this, you should pull out the connector going to the socket itself. To get to it, you will need to remove the decorative plastic from the front of the central tunnel. The connection diagram, as well as the pinout of the cigarette lighter and fuse are shown in the photo.

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.

Common causes of problems

The parts that are used most often are the first to become unusable. Such elements include the cigarette lighter, since you often have to connect various devices and devices to it. The most common breakdowns are:

1. Heater combustion. This happens when high-voltage devices and tools are frequently connected, for example, a compressor for inflating tires.
2. LED bulb burnout.
3. Contacts are dirty or oxidized. The connection between the antennae and the cigarette lighter is lost as a result of the formation of oxide on them. This happens often with copper elements.
4. Fallen wires. An age-related “disease” of almost all cars.
5. Fuse blown. Occurs as a result of a voltage surge or short circuit. To resuscitate the element, you will need to simply replace the Priora cigarette lighter fuse on the common unit. It is marked F13.

These problems are the simplest, and solving them will require no more than half an hour of personal time.

Disadvantages [ edit | edit code]

The cigarette lighter is not a reliable electrical connection. Its design itself did not provide for long-term and reliable switching of high currents. Reliable fixation of the consumer plug in the cigarette lighter socket can be ensured by an increased number of clamping tabs, but so far there is no uniform standard for such a connection. In practice, non-standard forks have only a spring-loaded central contact and two mass clamping pads. In the socket, the central contact area can be located deep, or maybe close. The grooves for the presser feet (even if they are present) may not be located where they are located on the fork. The cross-section of the contacts themselves is not enough to switch large currents. Due to various vibrations and shocks while driving, reliable contact between the plug and the cigarette lighter socket is lost, the connection sparks, and the possibility of a short circuit cannot be ruled out. In addition, a modern car uses a large number of connected devices simultaneously: navigators, video recorders, chargers for small batteries, televisions, walkie-talkies. For this purpose, various tees and splitters are used, which by themselves cannot add reliability. The impossibility of a sudden transition to a connection with greater reliability is explained by the fact that the cigarette lighter in the form in which it is now is a de facto standard in cars and its trouble-free operation can be guaranteed only when used for its intended purpose - to heat up the spiral insert.

When using a car, many car owners simply do not think about the fire safety of the car. Whereas car fires due to problems with wiring, a faulty battery and the use of low-quality electrical appliances are observed all the time. How to avoid burning your car when using the cigarette lighter connector to power various car accessories.

If 20-30 years ago we used the cigarette lighter socket exclusively for its intended purpose, today this connector is indispensable for receiving electricity from the on-board network. However, the use of low-quality wires, adapters and all kinds of plugs leads to short circuits, which can damage the cigarette lighter itself, and in extreme cases, contribute to a fire in the car.

The main differences in replacing the cigarette lighter on Lada Priora 1 or 2

There is no difference in working with different generations of cars. The design of the Priora cigarette lighter is identical for the first or second generation. Therefore, when making repairs, you should follow the step-by-step replacement instructions described earlier.

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.

Step by step replacement

1. Take out the cigarette lighter cylinder.

2. Using a flat-head screwdriver, pry up and remove the metal core of the cigarette lighter. It is best to do this from the inside so as not to damage the plastic.

If it doesn't come out, there may be clips on the inside of the core. They are most often metal. The photo below shows the location of the metal clips. Using a flathead screwdriver, you can bend them and remove the core.

If you are changing the cigarette lighter assembly, I think there is no risk of damaging something on it.

3. Remove the plastic bezel that is illuminated. This can be done using a flat-head screwdriver.

If your bezel backlight works and the bezel itself is not damaged, then you do not need to change it. Simply disconnect the non-working cigarette lighter core, connect a new one and put everything back together.

Power to the cigarette lighter comes through the terminal block. This means it is not difficult to replace it.

4. The backlight bulb is assembled with a plastic rim. To replace the light bulb, remove the small plastic cover.

Next, insert a flat-head screwdriver as shown below and pull the edge toward you. There is a small groove on the body and the light bulb is held in place by it. I think everything will be clear from the photo below, but if you have any difficulties, watch the video tutorial.

5. Remove the lamp from the socket and install a new one. The light bulb simply pulls out towards itself.

6. Install the socket with the new lamp into the rim. Be sure to align the grooves so that the cartridge snaps into place.

7. Install the small plastic cover.

8. Put the rim in place. There is a groove in the floor tunnel and a corresponding groove on the rim body. When installed, they must match and the light bulb must face backwards.

9. Change the cigarette lighter core and install it with the metal contact back until it clicks.

When installing, the contact should be backwards, just like the light bulb. Power is supplied to the backlight through this contact.

10. Install the cigarette lighter cylinder.

After reassembly, we connect the battery terminals and check the operation.

Fuse box in the passenger compartment of VAZ-2170, -2171, -2172

The fuse box in Priora is located at the bottom of the dashboard, on the left side of the steering wheel. To get to it, you need to open the cover, which is held on by three latches. Rotate each locking knob 90 degrees and pull the lid down and it will snap open.

Fuses in the interior mounting block

F1 (25 A) - radiator cooling fan. If your fan does not work, check its motor by applying 12 V directly to it from the battery. If the engine is working properly, then most likely the problem is in the wiring or connectors. Check the serviceability of relay K1.

The fan in the Priora usually turns on at a temperature of 105-110 degrees. Do not allow the engine to overheat, watch the arrow of the temperature sensor.

If the fan runs constantly and does not turn off, check the coolant temperature sensor located on the thermostat. If you remove the connector from the working sensor, the fan should turn on. Check the wiring to this temperature sensor, as well as the contacts of relay K1, move this relay, clean the contacts. If this is the case, replace it with a new relay.

F3 (10 A) - high beam, right headlight. F4 (10 A) - high beam, left headlight. If the headlights do not shine on high beam, check the K7 relay and the headlight bulbs. The steering column switch, wiring or connectors may also be faulty.

F5 (10 A) - sound signal.

If the signal does not work when you press the steering wheel button, check relay K8. The signal itself is located under the radiator grille; you can get to it by removing the plastic casing from above. Check it by connecting the voltage to 12 V. If it doesn’t work, try turning the adjusting screw, or replace it with a new one.

F6 (7.5 A) - low beam, left headlight. F7 (7.5 A) - low beam, right headlight. When replacing lamps, be careful; there are separate lamps for the low and high beams, so they can be easily confused. It is better not to install lamps in high-power headlights; the reflectors may melt and the desired effect will not be achieved. Most low beam headlight problems that cannot be corrected by conventional means can be related to the light control module (LCM). The low beam relay is only available in cars equipped with a light sensor, it is located in the place of relay K1; on most cars this relay is not in the mounting block; the low beam circuit goes through the MUS block. It happens that the tracks in the block burn out; if there are problems, it is better to replace it with a new one. If the windshield wipers turn on spontaneously when the low beam is not working correctly, the problem is most likely in the windshield wiper control unit, located in the center of the dashboard, the topmost block, next to the radio, is best reached from the glove compartment, or by hand through the removed console covers at the feet.

F8 (10 A) - alarm signal. If the alarm does not work, also check relay K9.

F9 (25 A) - stove fan.

If your stove does not work in any mode, the problem may be with the stove speed controller or with the engine. Check the stove motor by applying 12 V voltage directly to it. If it does not work, remove it, open the cover and check the condition of the brushes. If the stove does not work only in the first modes, but works in the last mode, most likely you need to replace the heater resistance, located under the hood on the fan scroll.

The price of these resistors is about 200 rubles. Also check that the filter and all pipes are clean and that air flows normally into the stove. If the stove fan squeaks or turns with difficulty, try lubricating it. If the stove turns on and off, check the connectors and contacts in them, they could have melted or oxidized, in this case, replace the connector.

Standard instrument panel - article number and price

The original car tidy exists in three types.

• the first is an option for a pre-restyling car;
• the second panel is for a restyled car;
• and the third is the “Lux” option for the restyled one, which has become faintly similar to all previous torpedoes.

Each of them contains standard elements such as a tachometer, so their functionality does not decrease. . Who wants to do tuning of the instrument panel, this option is for them.

Priora first generation

The instrument cluster for the first generation Lada Priora received catalog number 2170-3801010. Cost – about 6,000 rubles. Everything is standard with it - from left to right there are four arc scales with red arrows: odometer, speedometer, coolant temperature, fuel level. Below the speedometer there is a small on-board computer display, and above the arches are all the indicators, including the direction indicators.

Priora 2

For the Priora “Lux” variation there are two more “subtypes” - with or without a CAN bus. Different subtypes were made so that the panel could be connected to any car. Catalog number – 2170-3801010-50 without tire, 2170-3801010-60 with tire. It is distinctive in that it contains an elongated display with a screen that can highlight the navigator.

The catalog number of the combination for the “Norma” assembly is 21720-03801010-20. Cost – 6,500 rubles. Like the “Lux” version, it received a brighter speedometer and odometer, and the coolant temperature along with the fuel level indicator is hidden at the bottom of the speedometer and odometer. The base will not create a route on the display, but will show all the information in color.

Replacing the cigarette lighter for VAZ 2110, 2111, 2112

If previously only smokers used the cigarette lighter in a car, today it acts as a power source for DVRs, compressors, car refrigerators and many other devices, and with such intensity of use, replacing the cigarette lighter in VAZ 2110, 2111, 2112 cars may be required much more often.

The owner can carry out such repairs independently, without contacting a service station. But, for this it is necessary to at least understand the connection diagram of the node to other modules of the on-board network.

Required spare parts

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

Important! Before purchasing new spare parts, you need to determine exactly what is faulty. There is one simple way to do this - try turning on the heater cooler

Only at first glance there is no connection between them, but these two devices are controlled by one fuse - F18. Therefore, if the fan also does not work, the problem is precisely this element. But if the cooler starts, then you need to change the cigarette lighter.

Tools required for repairs

To install the cigarette lighter of a VAZ 2110, 2111 or 2112, you will need a few tools - small tweezers, a Phillips and flat-head screwdriver. But this does not mean that the operations are simple, since many connectors need to be disconnected. But the measures are economically feasible, since at a car service center you will pay at least 250 rubles (as of May 7, 2019). In addition, you will waste your personal time on the road, waiting and gasoline.

Important! The operation of the cigarette lighter is controlled by two fuses F6 and F18. Most often problems are associated with the first element

It needs to be checked first if the node is not working. The second one is connected to the illumination of the glove compartment, which needs to be opened. If there is no lighting, you need to check fuse F18 and look for short circuits in the electrical circuit.

Order of Operations

Before removing the cigarette lighter of a VAZ 2110, 2111 or 2112, you need to de-energize the circuit; to do this, remove the negative terminal from the battery. Now you can start working directly:

1. It is necessary to remove the plates on each side of the instrument tunnel; to do this, unscrew two bolts from each. On the right side, disconnect the backlight and cigarette lighter connector.
2. The housing of the unit is fixed to the casing of the instrument tunnel; it must be removed. The trim is located under the handbrake lever. It can be easily removed with a flat screwdriver.
3. Also, using a flat-head screwdriver, you now need to pry and remove the housing from the gearbox shift lever.
4. There is a screw under the cover; you need to unscrew it with a Phillips screwdriver.
5. Now the driver and front passenger seats need to be moved back and the gearbox screws unscrewed. There are five of them.
6. You need to remove the top cover of the instrument tunnel. Now the cigarette lighter is accessible. You can remove its cartridge. Then the screen is removed so that the tabs come out of the grooves on the light guide.
7. Use a flat-head screwdriver to press the latch next to the cigarette lighter socket, so it is released from the light guide.
8. Now you can remove the assembly along with all the elements.
9. Then you need to tighten the latches on the light guide, so it is immediately disconnected from the assembly.
10. If you need to change the LED itself, it can be easily removed by pressing the tabs on the housing. When installing a new device, make sure that the slot in the casing aligns with the protrusion on the housing.
11. Now you can begin installing the new cigarette lighter. First, it is connected to the light guide, the following operations are performed in the reverse order.

Removing the instrument panel

To remove the shield you will need a flathead and Phillips screwdriver.

Unscrew the two top screws (as shown in the picture), then carefully remove the panel under the steering column. It is held on top by clamps, and on the bottom by 3 fasteners that just need to be turned.

Under the panel we see 2 more self-tapping screws for fastening the shield; we also unscrew them. Now lower the steering wheel to the lowest position and remove the plastic cover of the shield.

Now all that remains is to unscrew the two screws holding the dashboard itself. They should be unscrewed carefully, as the screws may fall under the panel. It is better to unscrew them with a screwdriver with a magnetized tip.

We pull the panel slightly towards ourselves and see the green block and wiring harness. Disconnect it by pressing the “tab” and pulling slightly upward. After which the instrument panel will be removed.

We disassemble, repair the cigarette lighter and replace its socket.

An option such as a car cigarette lighter is relevant not only for heavy smokers. For example, to connect a portable compressor to inflate tires, you cannot do without a working cigarette lighter socket. But what if it doesn't work? With a little knowledge, you can make this simple repair yourself.

Required tool for repair.

1. Forceps, small size;
2. Solder;
3. Soldering iron;
4. Carrying or flashlight;
5. Pliers;
6. PVC tape

Let's move on to repairing the cigarette lighter directly.

The first step is to de-energize the car by removing the negative wire from the battery. Open the car door and find the cigarette lighter socket. We remove the heating coil (the cigarette lighter itself) from the socket. We apply a beam of light into the formed nest; if foreign objects are detected, they must be removed using forceps or tweezers. Let's move on to checking the fuses. We find the fuse block, open the cover and pull out the required fuse from the socket (see the technical instructions of the car, or the inside of the cover). If the fuse has a blown jumper, it needs to be replaced. The next step, if the previous steps were in vain, remove the cigarette lighter from the hole. We take pliers in our hands and carefully, holding the rim, pull it towards ourselves without any effort. Under no circumstances should we make sudden jerks; you need to pull smoothly, otherwise you may damage the wires. After removing the element, we inspect the place where the wire is soldered to the cigarette lighter body. If a break or the slightest disconnect is found, it should be soldered

You also need to pay attention to the integrity of the wire insulation. Identified abrasions should be isolated with PVC tape. After making sure that the cigarette lighter is working normally, with a gentle movement, without effort, we immerse the repaired element into the hole.

Repair and replacement of cigarette lighter socket

Disconnect the battery, remove the cigarette lighter from the socket, use a thin screwdriver to bend the latches, pry up the steel inner part of the socket, carefully disconnect the connector, replace the socket, install everything in the reverse order, reconnect the battery

If you need to replace the cigarette lighter light bulb, you need to pry the socket holder with a screwdriver and remove it, replacing the light bulb.

Instructions for changing the cigarette lighter bulb

This breakdown is also one of the most common. Replacing the cigarette lighter bulb yourself is not difficult. It is enough to follow the instructions.

1. Open the hood and disconnect the battery terminal.
2. Use a thin screwdriver to pry up the green plastic latch and turn the metal cup, pulling it out.
3. The burnt out lamp is inside a plastic part.
4. Disconnect the connector from the contacts.
5. Now you can change the light bulb with a working part.
6. We reassemble in reverse order.

Priora cigarette lighter connection diagram

Some people consider the cigarette lighter a completely unnecessary thing in the car. But drivers who keep up with modern technical progress have been using it to their full potential for a long time.

Using it instead of an outlet, you can connect various useful devices and devices to the car's power supply. You can comfortably spend time in the cabin of your Lada Priora, relaxing on a massage cape and drinking coffee brewed in a portable car coffee maker.

Replacing the cigarette lighter on a VAZ 2112

But sometimes little troubles happen: when you connect your favorite gadget to the cigarette lighter socket, you see that it does not work. In this case, an inexperienced car enthusiast may panic, not suspecting that a blown cigarette lighter fuse is most often to blame. Changing it is quite simple, but first let's figure out where the Priora's cigarette lighter fuse is located.

What fuses ensure the operation of the cigarette lighter?

In a Lada Priora car, the cigarette lighter fuse is installed in the mounting block. To find it, the driver sitting behind the wheel inside the car just needs to look down and to the left.

The unit is mounted at the bottom of the instrument panel, on the left side of the steering wheel, and is covered with a protective cover. Below it is the entire mounting block of this car. In its lower part there are two rows of fuses. The location for installing the cigarette lighter fuse is located in the top row, farthest to the right. It is marked F13 and is designed for a current of 15A.

In addition, in Priora cars, the cigarette lighter fuse is also located in the main fuse box. This element is responsible for the cooling system fan, but it also ensures the operation of the cigarette lighter. Its marking here is F3, the current limit is 60A.

The cigarette lighter fuse on a Priora has to be replaced quite often. The reason for this is incorrect use of the cigarette lighter itself. Many drivers are not interested in car repairs and are not electricians. Some people just don't have time. Therefore, they don’t even think about the fact that the cigarette lighter may have current and power limitations. Many of us plug an electrical device that is too powerful into a socket, or, using a splitter, several at once.

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 the fuse work for the Priora cigarette lighter?

The cigarette lighter fuses are made in the form of fusible elements. They are designed to open the electrical circuit in case of excess power or short circuit, and protect other machine systems.

Structurally, such a fuse is made in the form of a plastic case with a special thread or plate that conducts electric current. The body itself is a system for fastening a fusible plate (thread) to the contacts of a block connected to the main electrical circuit of the Priora. In addition, Priora fuses are usually installed in a protective housing.

How to change the cigarette lighter fuse

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.

Replacing the cigarette lighter on a Priora and its backlight lamp

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.

What fuses determine the operation of the cigarette lighter in Priora

First question: where is it located? When considering a specific car, and in our case it is the Lada Priora, you can safely look for the cigarette lighter fuse we need and will certainly find it in the specialized mounting block, which is where it is installed. When the car owner is sitting in the car, all he needs at this moment is to look down to his left.

The so-called mounting block is located at the bottom of the dashboard, to the left of the steering wheel and is covered with a special protective cover. Just under this cover you will find the entire Priora mounting block with fuses. At the bottom of the block there are 2 rows with all kinds of fuses. The cigarette lighter fuse “settled” in the top row, and its place is on the far right. Factory marking of fuse socket F13. Also an important question: what fuse does it come with? In this case, the current should be 15 amperes.

In all Lada Priora models from the Russian Federation, without exception, the cigarette lighter fuse we are currently considering is also present in the main unit. This element is primarily responsible for the fan located in the cooling system, but also ensures the operation of the cigarette lighter. In the main unit under the hood, its factory marking is F3, and the current limit is 60 amperes, respectively.

It has been verified experimentally that on the Priora, which is popular in the Russian Federation, the safety element we need has to be replaced quite often. The main reason for this problem is that the cigarette lighter is often used incorrectly. Most car owners do not think about the fact that the cigarette lighter is necessarily limited in power and current. You cannot connect a fairly powerful device to the connector; it is also undesirable to use a device that distributes charge to several devices or gadgets. You need to purchase reliable fuses, and high-quality wires for your car will also help keep the overall wiring of the car in proper condition.

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 the official website).

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

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.

Device and how it works

The Lada Priora cigarette lighter is located in a standard place for domestic cars (VAZ, etc.) - in the central tunnel of the floor covering near the parking brake handle. The location in a visible place ensures ease of use of the device and accessibility of connecting wires from different devices. For comfortable use, the device is complemented by a backlight that turns on in the dark. The Priora 1 and 2 cigarette lighter designs differ in configuration and design, because... The nest is more compact than other VAZ models.

The design solution and operating principle of the cigarette lighter are standard. The cigarette lighter consists of a socket (a hollow cylinder made of alloy) and a metal socket. The cartridge is supplemented with a button, after pressing which the plus is connected to the minus by means of a spiral. The Priora brand cigarette lighter does not have a relay. The relay functions are performed using bimetallic elements built into the inner surface of the cartridge. After heating, the elements unclench, the spring presses on the cartridge, placing it in its original position.

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.

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.

Block in the engine compartment

The power fuse box is located in the engine compartment under the hood, near the left strut support. To get to it, you need to open the lid by prying the latch.

1 (30 A) - engine control system circuit . If there are problems with the electronic control unit, short circuits or other malfunctions, this fuse may blow out.

2 (30 A) - vehicle on-board circuit . 3 (40 A) - vehicle on-board circuit .

4 (60 A) - generator circuit.

5 (50 A) - electric power steering circuit.

6 (60 A) - generator circuit.

In case of any problems, it is important not to panic, to think soberly and logically. The most important thing is to diagnose and establish the cause of the breakdown. If you don’t have enough experience or nerves, it’s easier to sign up at the nearest car service center if it has a competent electrician.
