Connection diagram for the Priora rear window heating button

“Seven” is still popular, they are bought, then sold, then bought again. This is the most advanced model of the classic Lada.

The rear window heating schemes for each car brand are different, but for models of the same family they are approximately the same. The VAZ 2107 heater circuit is simple. You should look for the reason for the intermittent or completely non-functioning glass heater in the electrical circuit diagram. Heated glass does an excellent job of preventing fogging, but it happens that the heater is working, the heating is working, but the glass in the car still sweats.

What does computer diagnostics of the heater control unit reveal?

Carrying out this diagnostic procedure allows you to find out the status of all sensors. Check the software installed in the heater ECU. Find out the performance of the micromotor reducer of the Priora heater. And adjust the units. This operation, adjustment, allows the computer to more accurately produce the temperature closest to that set by the driver. That is, by manipulating the damper, the ECU combines the sensor resistance data into a single system.

How and with what to carry out this operation

Computer diagnostics of the Priora heater control unit is done by pairing the vehicle equipment with a diagnostic device through a special diagnostic connector. It is located quite cleverly, behind the glove box, in common parlance the glove compartment. To access it, you need to pull out this drawer, located on the passenger side, all the way. On its back wall, at the bottom left side, there is a connector.

This type of diagnosis requires professional equipment. This is either a full-fledged motor tester, or a professional scanner such as “Auto-AS” and others. Only they have this function included.

How to do it

Connect the connectors and turn on the ignition. Wait for a connection signal from the equipment. Exit to the work menu. Find the option “SAUO heater” and turn it on. Then everything is the same as when diagnosing the engine ECU. First of all, check for errors. Then check the operation of the mechanisms using the “IM control” function.

Each diagnostic device has its own instructions. Before connecting the device, be sure to study them! Video on the topic of diagnostics "Priors". Checking the electrical package. The same algorithm for checking the heater:

Additional block

Additional relays are mounted on a bar and located under the dashboard, near the front passenger's feet. To get to them, you need to remove the right tunnel lining. Next to the additional relays is the electronic engine control unit (ECU).

If its connector interferes with access to the relay, disconnect it by first removing the negative terminal from the battery.

Circuit breakers

F1 (15 A) – main relay circuit, starter interlock.

F2 (7.5 A) – power circuit of the electronic control unit (ECU).

F3 (15 A) – electric fuel pump . If the fuel pump has stopped pumping (this can be determined by the absence of a sound when the ignition is turned on), check together with relay K2. There may also be problems with the immobilizer, it blocks the pump, see information about F20. If the wiring, this fuse and the relay are good, most likely the fuel pump itself has failed. To remove it, you need to disconnect the battery, remove the rear seat cushion, unscrew the cover, ring and fuel hoses, then carefully remove the entire fuel pump.

On one side, a plus “+” is supplied to the filament, and the other end of the filament is connected to a minus “-”.

Lada Priora in any configuration is equipped with a heated rear window and heated mirrors. The heated mirrors turn on when the heated rear window is turned on. The design of heating mirrors is based on the same system as with heating glass; filaments are glued to the mirrors, which warm the mirror and help it to sweat.

How to connect fog lights on Lada Priora?

When there is little left in the warehouse, just disassemble everything and install the PTF, then reassemble everything and enjoy the work done. Making fun of :-).

1. First we need to disconnect everything, to do this we remove the battery terminal.
2. Next, you should remove the bumper; to do this, in turn, unscrew the screws that secure it. The screws that need to be unscrewed are marked in the photo. After unscrewing all the fasteners, carefully detach the bumper from the clamps and completely disassemble it.

1. Next, take a screwdriver and disassemble the fog lamp sockets, which are attached with self-tapping screws.

1. We prepare our fog lights and proceed to an important stage called “installation of fog lights.” We carefully place the PTFs in their regular places and fasten them with self-tapping screws that secure the plugs. Then we start laying the wiring. The wiring is routed from the inside of the bumper; it is recommended to use corrugated cables.

1. The wires need to be pulled into the cabin in the GTZ area; to do this, we take out a special plug, under which the holes we need are hidden. For convenience, it is recommended to remove the trim along with the wipers, as well as the expansion tank with bracket.

1. In the cabin, to extend and connect the fog lights, pull out the trim (sound insulation) and stretch the cable through the cabin.

1. When the cables are brought into the interior, you can begin connecting. The diagram for how to connect is usually included with the PTF kit, but just in case I decided to follow the diagram.

1. Fog lights are connected to the button with the obligatory disassembly of the central panel. When installing the PTF relay into the unit, it is important not to mix up the wires and follow the PTF connection diagram.

Installing fog lights on a Lada Priora is a rather extraordinary task and can be done by any motorist. The only problem is communication; as a rule, difficulties arise with it. However, if you follow the instructions and carefully study the connection diagram, everything should work. If you encounter any difficulties during the connection, I recommend contacting an experienced electrician, he will easily help you with minimal costs. Before final assembly, do not forget to check everything and make sure that your PTFs are in good working order.

Everything is there, thank you for your attention and see you again at VAZ Repair! Goodbye!

Hi all! I want to share with you my method of connecting fog lights a priori.

I decided to connect the fog lights to the ignition and ended up with 3 modes, even unexpectedly for myself.

Since I first connected the fogs to the ignition (I’ll tell you right away if you’re too lazy to read, the final method will start in step 3):

1) I first made a standard connection for the fogs. (fog lights, relay, button (where the clock is, not through the mus)) here is a diagram from the Internet, with a standard connection:

2) further. I connected the device to the ignition and removed the + from the heating button. The fact is that regardless of the location of this button (on or off), a plus sign appears. On this bait, I used it from here, or rather, to activate the relay, an advantage is needed, i.e. we already get the following circuit:

3) I also didn’t like this pattern for three reasons: 1. There are no instructions to turn on the fog lights 2. The fog cannot be turned off until you turn off the ignition 3. The actual silent mode does not need to be turned on (and I didn’t want to remove the button) 3.1 eventually made changes into the circuit and connected the fogs so that I still have a button + indication + forced on/off. 3.2 How I did it: Let me tell you right away, I needed a small glass. I used 3 positions (on-off-on2) (it was already available), like this one (pictures from the Internet, but I definitely have them):

Installing fog lights on a Priora

Fog lights are necessary in poor visibility conditions: fog, heavy rain. Their main feature is the distribution of light flux over the road and along the edges, which significantly improves visibility in bad weather. The basic configuration of the Priora does not include fog lights. They should be installed to increase traffic safety on the road. Fog lights improve visibility not only for the driver on whose car they are installed, but also for all other road users.

Air conditioning systems

One of the consumers is a heating device. It is part of the climate control system. A control controller works with this system. The work is automatic. The driver only sets certain parameters.

On cars, the electrical circuit of a VAZ Priora may contain air conditioning systems. After pressing the button, the relay is activated, the compressor is turned on, power is supplied to the electromagnetic clutch, and the pump is turned on. The air conditioning turbocharger begins to rotate, creating pressure, and begins to regulate refrigerant through the system.

How to disarm the electrical package unit of LADA PRIORA

What to do if Priora is not removed from the standard alarm!

The hazard warning light blinks, the car does not respond to the ignition key buttons. As a rule, several units are involved here that are synchronized with each other.

1. Ignition
2. Radio channel module (Located in the driver's door)
3. Electrical package block (Comfort block)
4. Engine ECU

New blocks come with non-activated codes inside and can be installed on any car without problems, but once you register (train) the keys, a special code is written into all these blocks, which is synchronized with each other and serves as a standard alarm system. (Immobilizer) As soon as you turn the ignition key, within five seconds there is a poll between the key and the units, if the code matches everywhere, then the engine ECU gives permission to start, if the code of at least one device is not recognized, the engine ECU is blocked and the car does not start.

So I thought about it

Design of the rear window heating system

The system that helps clear the rear window of ice, snow or fog is not very complicated in design. The electrical circuit in general terms can be depicted as follows:

• C - generator.
• E230 - OZS system switch.
• J519 - on-board electrical network control unit.
• Z1 - heating element of the OZS system.

Although there may be some differences in different car models, nevertheless, if we consider it in detail, then in principle it includes the following main elements.

1. Mounting block.
2. Ignition switch.
3. Heating switch ZS.
4. Indicator lamp signaling the activation of the OZS.
5. Heating element of the OZS system.

K6 - additional relay. K7 - OZS switching relay. A - connection to power systems.

In addition, the system has fuses, terminals and wires that connect all elements into a single whole.

When the ignition key is turned, the OZS is turned on by pressing a button, to which power is supplied through an additional relay K6. At the same time, the rear window heating relay K7 is activated, the heating element is connected and at the same time the control light comes on.

The design of the heating element on the rear window may also vary. In the standard version, it is a mesh of thin metal nickel threads, which are connected by two conductive busbars located on opposite sides. On one side, a 12V current is supplied to the bus, and on the other, the bus is shorted to ground. Such devices are attached to the glass using special glue.

On some car models, the heating element is applied to the glass using spraying, for example, aluminum. A thin film with good light transmission is attached on top of this coating using glue that conducts current.

Interpretation of the symbols for the rear wiring harness of the VAZ Priora

The rear part of the electrical wiring chain is responsible for the vehicle's lighting and peripheral systems. This includes lights, locks and windows. The pinout of tips and terminals looks like this:

• 1 – dashboard response;
• 2 – power supply for the door behind the driver;
• 3/28 – power supply for the front passenger panel equipment;
• 4 – maintenance of power windows and door locks;
• 5-6 turn signals;
• 7 – interior lighting;
• 8 – handbrake indication switch;
• 9-10 – aft dimensions;
• 11 – temperature inside the car;
• 12-15 – circuit breakers for lighting the interior of the machine;
• 16/17 – power supply to the devices of the aft right and front left doors, respectively;
• 18/19 – voltage to the rear right and left speakers, respectively;
• 20 – cigarette lighter power core;
• 21 – EBN;
• 22 – contact group of the cargo compartment lighting circuit breaker;
• 23 – heated rear windshield;
• 24 – luggage compartment lighting lamp;
• 25 – additional stop;
• 26 – power line to the electric lock of the luggage compartment lid;
• 27 – power supply for rear number plate illumination;
• A1-4 – mass;
• ХР1/3 – electrical package power controller.

Pinout for rear license plate illumination of VAZ 2170

The small harness, located in the luggage compartment, has only three terminals:

• 1 – power supply to the stern license plate lights;
• 2-3 – license plate lighting lamps;
• 4 – trunk lid lock motor.

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.

F2 (25 A) - heated rear window . Check together with fuse F11 and relay K2. If the rear window does not fog up, the heating element threads may have broken. Inspect all the threads and if you find a break, seal it with special glue or varnish, which can be bought at car dealerships for 200-300 rubles. Check the connection contacts at the terminals to the heating elements at the edges of the glass, as well as the switch on the dashboard and the wiring from it to the rear window.

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.

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.

Device

Almost all stern window heater systems are identical and do not differ much from each other.

The entire system consists of several elements that ensure normal and safe operation of the heater:

• heating threads (their number may vary depending on the device model);
• electrical wires supplying current to the work area;
• device safety relay;
• power button equipped with a signal LED;
• fuse.

The failure of one of the component elements of the heating device or a break in its electrical circuit may prompt the question of why the rear window heating does not work.

Mechanism of operation

When the recirculation button is in the pressed (on) position, the electro-pneumatic valve opens, then a flap in the area of ​​the intake pipe extends and blocks the access of outside air to the vehicle interior.

The circulation system starts only when the engine is running and functions due to the coordinated operation of the valve-flap complex. Circulation in the car will continue as long as the fan is turned on, in which case the air flow passes through the heater ducts.

To determine the presence of this device in the car, first of all, there must be chips and a button in the cabin. When the ignition and recirculation button are turned on, there should be voltage on the chips.

Air conditioning system diagram

Then, it is worth checking whether the damper control valve and the electro-pneumatic valve are present. If this system is absent, you can block exhaust gases and smoke using a fan, but the damper isolates the car from the outside air much more effectively.

To regulate the level of humidity in the car and solve the problem of glass fogging, it is recommended to have an air conditioner in the VAZ model 2110.

Fault diagnosis

If the device breaks down, experts recommend diagnostics in the following sequence:

• the ignition and engine are turned on;
• the maximum fan speed is set;
• the recirculation button is pressed;
• the valve-flap mechanism starts.

If the movement is uniform and if the damper stops at the end point, in the first 2-3 seconds, this indicates the serviceability of the complex.

But pops, uneven movement, and clicks indicate a malfunction.

To extend the service life of the complex, it is necessary to install a stabilizer. Due to the operation of the stabilizer, where the damper is located, the torque of the electric drive is reduced. To eliminate the possibility of damage to the damper for the time before purchasing a stabilizer, the damper is disconnected from the electric drive by a wire.

Purpose of the air recirculation system

How is the recirculation mode useful? Firstly, it ensures a much faster establishment of the optimal temperature inside the car, especially after the car has been parked for a long time. This is achieved due to the fact that the intake of external air stops. Consequently, only the air that circulates through the heating or air conditioning system is involved in the blowing process. Accordingly, it does not cool in winter and does not heat up in summer due to mixing with the external flow, that is, its temperature almost immediately becomes optimal.

Secondly, if it is necessary to cool the cabin in the hot season, the energy consumption for operating the evaporator in recirculation mode becomes half as much as when using the oncoming external flow.

Thirdly, the mode for blocking the air intake from outside is very useful in cases where conditions outside are far from ideal in terms of the presence of various contaminants and unpleasant odors in the air. Such factors, for example, could be:

• driving on country roads with no hard surface - on such roads in the summer there is a column of dust, and any oncoming car threatens to turn the air in the cabin, even with the windows completely closed, into a dense suspension, which becomes impossible to breathe,
• driving in a traffic jam, when the virtual absence of dynamics and dense traffic lead to multiple concentrations of exhaust gases freely penetrating into the cabin,
• driving past sources of unpleasant odors - for example, a cow barn, pig farm, poultry farm, landfill or industrial complex with specific odors,
• movement in long tunnels in conditions of traffic jam speed, when stagnation phenomena greatly increase the concentration of exhaust,
• if foul-smelling or polluted outside air has already leaked into the cabin, and it’s still a long way from leaving for a clean zone, turning on internal recirculation will also be useful - the bad air is usually cleared quite quickly.

Note that, despite such useful features of the Priora’s air recirculation mode, its use should not be long-term, since there is no air exchange. This leads to a decrease in the amount of oxygen and a corresponding increase in the concentration of carbon dioxide. The latter, as is known, has a suffocating effect on the body, causing drowsiness in the driver and passengers. Therefore, long driving (more than 15 minutes) in this mode is not recommended, since it has a bad effect on people’s well-being.

The second negative point is that if you breathe the same air for a long time, it becomes saturated with moisture, which is abundantly present in a person’s exhalation. And if, in addition to the driver, there are also passengers in the car, an increase in air humidity leads to rapid fogging of the windows, which even the turned on air conditioner cannot cope with. From a physics point of view, fogging is the result of exceeding the concentration of moisture in the air, the so-called “dew point,” especially in the area of ​​the windshield, which always has a temperature lower than in the cabin. For this reason, climate systems in the “defrost” mode (defrosting the windows) automatically block the recirculation of cabin air.
