How to turn on the air conditioning on a Prior

The air conditioning button on the Priora is blinking

The air conditioner is not a critical component of the car. But if the air conditioning button on a Priora is blinking, it is better to try to quickly find out and fix the problem, without waiting for a serious breakdown and expensive repairs.

“Priora”: the air conditioner light is blinking

The “Priors” air conditioning switch has a green LED that starts flashing when the on-board computer registers a malfunction in the climate control system. It is almost impossible to determine the malfunction by the nature of the blinking. This could be either a breakdown or interruption in the operation of the sensors, or a lack of antifreeze in the system, breakdown of parts of the air conditioning system, or problems with the power supply of the unit. In rare cases, the problem may resolve itself, for example, a sensor malfunction due to high air humidity. But usually breakdowns require the intervention of a specialist.

How to count an air conditioner malfunction

If you turn on the climate control of the Priora and the air conditioner light blinks, you can find out the cause of the malfunction by connecting the tester to the on-board computer.

This device reads information from the computer and displays detected error codes on the screen. After this, the codes require decoding according to the tables corresponding to the car model. This not entirely convenient method is due to the fact that cars are produced for markets in different countries and the text description of the problem would still require translation. Codes are a universal, convenient way to present information. In order to understand why the air conditioner button on the Priora is blinking, you need to read the error code, which contains four digits. After correct decoding, troubleshooting will be easier and faster.

Air conditioner fault codes on Priora

If the air conditioner light on a VAZ Priora is blinking, the malfunction can be determined based on the error code read from the on-board computer. Depending on the code, the causes of the malfunction are as follows:

9338 - the temperature sensor located in the cabin is faulty; the sensor wire is broken or the connector is oxidized;

9337 - the temperature sensor located in the cabin, or the wire going to it is shorted to ground;

9348 - the sensor recording the ambient temperature is faulty, or the electrical circuit for its connection is broken;

9347 - the sensor circuit that records the ambient temperature is shorted to ground;

9378 - the evaporator sensor is faulty or the electrical circuit going to it is broken.

9377 - the electrical circuit of the evaporator sensor is shorted to ground;

9358 - the wire coming from the radiator sensor of the heating system is shorted to ground;

9412 - short circuit in the electrical circuit of the air mixer micro-reducer;

9413 - the electrical circuit of the micro-reducer is broken;

9420 - the electrical circuit of the micro-reducer winding is closed;

9426 - the electrical circuit of the micro-reducer winding is broken;

9440 - the power supply circuit of the additional resistor that regulates the speed of the heater fan is broken;

9860 - overvoltage of the on-board network;

9861 — low voltage on-board network;

9607 - malfunction of the air conditioning system controller.

Air conditioner troubleshooting methods

If the air conditioning button on a Priora blinks, after reading and decoding the fault code, you need to fix the problem. Some faults can be eliminated yourself, without contacting a specialized service station.

If the computer signals an open circuit of the sensor (micro-reducer, resistor), you should check the connection connector, then the sensor (micro-reducer, resistor), then ring the wire.

If the error code indicates a short circuit, you need to unplug from the electrical unit and ring the wire and, if it is not closed, check the sensor itself or another device.

If the error code indicates low or high supply voltage, you should make sure that the generator relay is working properly or has bad contacts.

If the air conditioner on your LADA does not work well or does not turn on

LADA cars are equipped with a compressor type air conditioner. During operation, malfunctions may appear in the operation of the climate system (does not turn on, is noisy, hums, or does not cool well). If you encounter similar problems, you can determine the cause of the breakdown yourself.

1 – capacitor; 2 – pipeline connecting the compressor to the evaporator; 3 – pipeline connecting the condenser to the evaporator; 4 – pipeline connecting the compressor to the evaporator; 5 – thermostatic valve; 6 – evaporator; 7 – compressor; 8 – pipeline connecting the compressor to the condenser; 9 – pressure sensor.

The air conditioning device on all modern LADA cars (XRAY, Vesta, Largus, Granta, Priora, Kalina and Niva 4x4) has no fundamental differences. Therefore, checking its operation is carried out in a similar way.

Air conditioning on Priora - all the details, connection instructions

Comfort in the car is achieved through comfortable seats, a working stove, air conditioning and many other details. Air conditioning is not installed in all cars, underestimating its role. On the Priora, for example, this is a luxury package.

In summer, it helps combat the heat - with open windows and conventional climate control, it’s not always comfortable. But when a Lada Priora with air conditioning is stuck in a traffic jam, the driver and passengers will still not be hot - there is no wind outside, but a pleasant microclimate is created. Climate control on the stove is good, but it’s still not air conditioning.

The scale of the disaster can be assessed using a sensor that records the ambient temperature. It transmits the received data to the dashboard display. It is impossible to reduce the temperature without moving in a standing flow - and they are trying to fight this. in Priora it is quite an expensive pleasure, and experienced car enthusiasts install air conditioning after purchasing a car. The price depends on the brand Hull or Panasonic, the first starts from 30 thousand. Installation is also not cheap, starting from 8 thousand. You can sell a Priora with air conditioning at a higher price.

The air conditioner for the Priora car is produced by Russian and foreign companies. The price is indicated for a set with highways. The kit is so convenient and functional that you can view the air temperature on the display of the air conditioning control panel, which is mounted in the center console.

Operating mode of climate control and air conditioning on Lada Priora

The factory installs climate control on the Priora in all trim levels, and in all air conditioners it is turned on in the “Auto” position. In this mode, the electronic control unit, which is located behind the center console, receives data on the ambient air temperature and the interior air temperature. Based on this data, the ECU regulates the “force” that the “conder” produces to maintain the mark set by the person.

For example, if a person has set a constant temperature of +19 ֯С, the ECU will regulate the power of the air conditioner, constantly sending it commands. Working at this pace, the air temperature in the cabin will be maintained at +19 °C.

About refilling the air conditioner

You need to pump 500 g of refrigerant into the Priora air conditioner. Until 1995, R12 freon was pumped into air conditioners, but it was considered toxic due to its high fluorine content. Therefore, R134A freon is now in use. Preparing for refueling looks like this:

special cleaning foam from a can is pumped into the air conditioner radiator;
the radiator closes. The car engine starts and idles. At the same time, the air conditioner turns on. It must run for at least 15 minutes so that the foam passes through the entire recirculation system;
vacuum is performed. A pump is connected to the air conditioner, which removes air from the system along with foam and moisture.

Refueling

To refill the air conditioner, the driver must purchase a metrology station and a can of freon.

High pressure hoses in the station are always red, low pressure hoses are always blue

The station is a system of hoses, adapters and pressure gauges connected to the air conditioner.

The station hose is connected to the low pressure fitting on the air conditioner pipeline (it is usually painted blue or has the English designation “low”).
Tube fittings are usually marked “high” and “low”
The engine starts and idles, and the number of revolutions per minute should not be lower than 1400 (for this you will have to fix the gas pedal with something, or ask someone for help).
When the engine is running, maximum recirculation of the air conditioner is turned on, then the low pressure valve at the station smoothly opens.
The freon cylinder is turned upside down, after which the tap is opened on it.
The refrigerant begins to flow from the cylinder into the system. At the same time, the driver controls the pressure using a pressure gauge - it should not exceed 280 kPa.
When the air in the cabin warms up to a temperature of 10–15°C, refueling stops.

Operating principle of the air conditioner

In a sealed air conditioning system, a refrigerant, freon, continuously circulates, which is mixed with a special lubricant that is resistant to freezing. A compressor is responsible for moving freon through the system, which builds up pressure in the heat pipes. After turning on the air conditioner, freon ends up in the heat exchanger located under the dashboard of the car. The internal structure of this device resembles a honeycomb. Once there, the refrigerant begins to take heat from the hot interior. At the same time, it quickly heats up and turns from a liquid into steam. Since the compressor continuously pumps up pressure in the system, the steam goes into the blown radiator, where it cools, again becoming a liquid, which again ends up in the heat exchanger.

Is it possible to install air conditioning on a Priora?

The Priora initially provides the design possibility of installing an air conditioner. A car owner who decides to install this device on his car will not have to make any modifications. All the necessary holes and buttons are already on the dashboard, and space for heat pipes and electrical wiring is also provided. Thus, installing an air conditioner on a Lada Priora is completely legal, and government officials will not have any questions for the driver.

Where is it located and how is it removed?

VAZ designers placed the DTVS module in a very original way. It is located in the plastic housing of the interior lighting unit. Directly under the rearview mirror. Under two backlights for the driver and passenger, you can see the air intake holes for supply to the combustion engine.

The module is dismantled quite simply. First, the rearview mirror is removed.

After this, two bolts are opened that secure the light module to the body and upholstery. They are simply unscrewed with a screwdriver or hexagon, depending on the type of bolts. When this unit begins to separate, it becomes possible to disconnect the wire connectors from the Priora interior air temperature sensor and directly from the backlight unit.

The DFA itself is a plastic box secured to the module body with two screws. And a wiring harness with a connector coming out of it. By unscrewing these bolts, you can freely separate the diesel fuel assembly.

And when the node is removed, various actions can be carried out with it. But most often, this is simply cleaning and lubricating the fan. Or replacing one of the nodes.

Although practice shows that most often drivers prefer, without bothering too much, to simply replace the complete combustion engine assembly. It’s really simpler, since its cost is not so high. Around 400-500 rubles.

And installing a new one according to the description above, proceeding in the reverse order, is generally not difficult.

And you can watch a short video on this issue:

There is no need to explain why you need air conditioning in a car - the heat sometimes reaches about 0 and above, and even more in the car interior. This is very uncomfortable and even dangerous for the driver and passengers - you can get heatstroke. Open windows are not an option. The noise of the street will accompany you all the way. And this is of little use if the air is very hot.

Car air conditioning is no longer a new product - it can be ordered when purchasing any new car, even a domestic one. For most of them, air conditioning is already offered as standard.

And if there is no air conditioning, if desired, you can even install it on a VAZ “classic” - there are now enough specialists and equipment. However, in recent years, instead of air conditioning, more and more car buyers are ordering climate control in Priora.

How does the Priora climate control differ from a conventional air conditioner? If you have a simple air conditioner in your car, then you have to do everything manually - turn the air cooling on and off, adjust the temperature, strength and direction of the air flow.

This is certainly better than frying in a frying pan, but still not very convenient. You have to constantly be distracted from the controls in order to adjust the climate in the cabin so that everyone is comfortable - or ask passengers to adjust something.

If your Lada Priora car has climate control installed instead of an air conditioner, then, of course, you can be envied. The driver only sets the air temperature with the regulator - the climate control system does the rest. It monitors the current thermometer readings in the cabin and, in accordance with this, changes the ratio of hot and cold air flows, as well as the strength of the flows supplied to the cabin.

Climate control on Priora can be two-, three-, or even four-zone. In this case, the driver and passengers can each set the temperature in their own part of the cabin, independently of each other (or with a certain maximum difference).

Such systems, however, are not always effective - it depends, first of all, on whether the manufacturer has saved on the number of fans, air tunnels and other parts of the climate system.

As for the main malfunctions, everything is quite interesting. An ordinary air conditioner is a fairly simple thing; repair and maintenance are not particularly difficult (among the main faults are rupture of tubes, breakdown of the compressor and evaporator, insufficient level of freon in the system).

Climate control on the Lada Priora is a much more complex device, and therefore mechanics have to rack their brains over its malfunctions much more.

On a Lada Priora car, the climate control is single-zone, but still, it includes, in addition to the usual components of the air conditioner, many control modules (especially an expensive part), sensors, sensors, cables, electric motors, resistors, printed circuit boards and other things. When replaced, these parts can cost a pretty penny!

Yes, it seems that everything is in the signature and in the text - Priora, mileage 40 tkm, Panasonic air conditioning.

What is the outside temperature?

Now the “snowflake” is burning, the condo is silent. No error appears.

There is no characteristic noise. The temperature is at a minimum. I've been with him for a long time - and I'm not a blonde.

Either the pressure sensor barked, or it needs to be refueled. If there is insufficient pressure, it will not turn on. Have you ever served?

Never. Is this a warranty case by the way?

I've been with him for a long time - and I'm not a blonde.

Yes, no one doubts

You just know that the first thing when a malfunction occurs is that the “snowflake” starts blinking or doesn’t turn on at all. And it's burning for you. Try turning the temperature up first to maximum and then to minimum when the air conditioner is on. Pay attention to whether the air temperature will change, especially in intermediate positions.

Either the pressure sensor barked, or it needs to be refueled. If there is insufficient pressure, it will not turn on.

The “snowflake” will immediately blink (as if it’s time for diagnostics), and then it will display errors for the pressure sensor.

My IMHO is this: the temperature of the evaporator is below +5C, therefore, in order to prevent frostbite of the latter, the clutch does not turn on (to warm up the evaporator). At the same time, the “snowflake” burns as expected.

Either the pressure sensor barked, or it needs to be refueled. If there is insufficient pressure, it will not turn on. Have you ever served?

Never. Is this a warranty case by the way?

If there is a sensor, then there is a guarantee, but if there is simply not enough gas, then there is no guarantee. The air conditioner needs to be serviced once a year, just like we change the oil in the engine.

I've been with him for a long time - and I'm not a blonde.

Yes, I turned the temperature, there was no effect. So the burning “snowflake” confuses me. Could the sensor that measures the temperature at the evaporator have failed (or simply started lying)? Outboard +10 shows. Usually, if the air conditioner turns on, the revs increase and the engine pulls worse, and the Carlson turns on like crazy. And then there is silence.

Either the pressure sensor barked, or it needs to be refueled. If there is insufficient pressure, it will not turn on. Have you ever served?

Climate control in Priora

Car air conditioning is no longer a new product - it can be ordered when purchasing any new car, even a domestic one. For most of them, air conditioning is already offered as standard.

Such systems, however, are not always effective - it depends, first of all, on whether the manufacturer has saved on the number of fans, air tunnels and other parts of the climate system.

Climate control on the Lada Priora is a much more complex device, and therefore mechanics have to rack their brains over its malfunctions much more.

Air conditioner malfunction

A Conder can break down; the reason for this is not always the negligence of manufacturers towards their product. Most often, a small component fails, which can be easily replaced and then continue to use the Conder. If the air conditioner does not turn on, then:

There is damage in the wiring;
Thermostat is faulty;
The fuse has blown;
Lack of freon in the system;
Pressure sensor malfunction;
Excessive system pressure.

If the air conditioner does not work, then this is not a reason to throw it away. All the necessary spare parts for an air conditioner can be found in Lada, they will not cost much.

How to find out which air conditioner is on the Priora

There are not many differences between the Halla and Panasonic cabin air conditioning systems, but they still exist

The first thing you need to pay attention to is the climate control unit

The middle button (air flow direction) has a glass blowing function. When you press it, the stove fan turns on at maximum speed and the air conditioner turns on.
In the extreme button (air flow speed), Panassonik has more than 15 speed positions.
The hose from the air conditioning compressor is soft, rubber

There is a plug in the middle button (direction of air flow).
In the extreme button (air flow speed), Halla has four blowing speed positions.
The hose from the air conditioning compressor is rigid, aluminum

What does the air conditioning system in Priora consist of?

Regardless of the company, the air conditioner kit for Lada should contain the following elements:

Air conditioning compressor assembly;
Condenser with receiver assembly;
Evaporation block assembly;
Air conditioner radiator for Lada Priora;
Highways;
Cushion bracket;
Generator bracket;
Tensioner bracket;
Tensioner roller;
Compressor drive belt;
Rubber seal;
Installation kit;
Wire harnesses.

About choosing an air conditioner for Priora

Today, air conditioners of both domestic and foreign production are presented on the market. They all have both advantages and disadvantages. Let's list them.

"August"

Domestic air conditioners "August" are in constant high demand among Priora owners. First of all, because of the affordable price.

Air conditioners "August" are in great demand due to their affordable prices

But “August” also has disadvantages:

the evaporator body is made of plastic, so it is very easy to damage;
The reliability of the compressor raises questions. For some reason, this device almost always fails before all other elements of the air conditioner.

Halla and Panasonic

Halla air conditioners are produced in South Korea. AvtoVAZ began installing them on Prioras in 2010. And by 2012, Japanese air conditioners from Panasonic began to appear on cars.

Halla is one of the most expensive and most reliable air conditioners on Priora

Both devices are considered quite reliable, the differences between them are minimal:

compressor design. Panasonic devices have vane compressors with a volume of 110 cm³. And the Halla air conditioner has a piston-type compressor, and its volume is larger - 160 cm³;
in Halla air conditioners, cabin filters are held on by plastic latches, in Panasonic - on self-tapping screws;
The heat pipes on Halla air conditioners are made of aluminum, while Panasonic has about half of metal pipes, the rest are flexible hoses.

The conclusion from all of the above can be drawn as follows: the choice of compressor for the Priora today is determined solely by the thickness of the car owner’s wallet. The best (and most expensive) option would be to install a Halla air conditioner. It was these air conditioners that were installed on almost all export Prioras. Their price is from 30 thousand rubles. The second number is Panasonic, which will cost the car enthusiast 25 thousand rubles. And if money is tight, you can buy “August”. Price - from 20 thousand rubles.

Factory air conditioner, Halla and Panasonic - differences, articles

Most often, Conders from August, Panasonic and Halla are considered as an installation option. The Russian product is cheaper, but it has its disadvantages:

Short-lived compressor;
Lack of cabin air filter;
To charge coolant you will have to remove the radiator;
The evaporator housing is made of plastic and is easily deformed.

But there is good, healthy competition between the other two brands. If you look at and buy Halla or Panasonic, you need to take into account their differences:

Airflow speeds. Panasonic has 16, Halla has only 4;
Halla's engine radiator will house the engine cooling fan along with the air conditioning condenser;
Panasonic's control knobs are capable of turning on the glass blowing, directing all the power only to them. Halla does not have such buttons or handles;
Panasonic's upper line is flexible, while Hull's is aluminum.

The entire Halla air conditioner for Priora can be purchased for around 30 thousand rubles - slightly cheaper than a kit from Panasonic. Installation of a Panasonic air conditioner in a technical center costs approximately 8,500 rubles, and Halla is a little cheaper (some prices are the same). It will be easy to distinguish them by article number. Panasonic has 2170-8122020-01, Calla has 2170-8122020-11.

How is self-diagnosis performed?

Press the button to start diagnostics
We have sorted out the main errors on the Priora, now it’s worth finding out how self-diagnosis is performed. The VAZ 2170 with 16 valves has a special controller with which diagnostics are performed. If you have an on-board computer installed, then diagnostics are performed on it. There is also special equipment that allows for a more in-depth check of Priora 16 class systems.

Since most Priora 16 cars already have an on-board computer, we will consider the option without the use of special devices. Diagnostics begins with activation of the test mode. The work proceeds according to the following scheme:

Turn off the ignition. Now we hold down the daily mileage reset button, without releasing the button, we start the ignition of the Priora 16 cl;
On the instrument panel you will see a display with an indication. After turning on the ignition, all components of the instrument panel will light up. The needles of the temperature, speedometer, tachometer and other instruments will begin to move to the maximum level and back. This behavior indicates that self-diagnosis has begun;
Let's move on to the right steering wheel switch. Here you will find a button for switching the on-board computer settings. Click on it, a message with the software version will appear on the instrument panel screen;
The instrument panel error diagnosis will begin if you press this key again. Various codes will appear on the display, which you can decipher in the table below;
When the diagnostics are complete, you can reset the error data. Press and hold the daily mileage reset button for about 5 seconds.

How to refill - instructions

We must not allow a decrease in the volume of freon - this will have a detrimental effect on the system. To independently fill freon into a car, you will need a test connector (a set of tools for manually filling refrigerant). Using it, you need to do the following:

Attach the freon cylinder to the Conder valve and turn the test connector valve. Press the gas pedal a couple of times.
Freon will be evenly distributed throughout the system. The main thing is not to overdo it, because if it is overloaded, the system will not work better.
Disconnect the cylinder from the system and close the valve.

Air conditioning is a necessary condition for comfort in the summer. Previously, it was not so necessary, because a person was unlikely to stand in car queues for several hours, under the scorching sun, and it was possible to ventilate the interior after parking in the heat by opening all the doors. If Conder has become accessible as a benefit, it means that it is possible and even necessary to use it.

Air conditioning can make a driver's life much easier in hot or cold weather. The problem is that when buying a new car, not all car enthusiasts have enough money for this option. Therefore, many car owners prefer to install air conditioners later, on their own. Let's look at how Priora owners do this.

How to properly use air conditioning in a car

There are many techniques that help reduce the load on the car’s air conditioning system, and therefore increase its service life:

1. When getting into a car whose interior is overheated in the summer heat, you should not turn on the air conditioning immediately after starting the engine. It is necessary to open all the windows, start driving, and ventilate the car a little naturally. At the same time, the unpleasant odors of overheated interior elements will disappear. After this, turn on the air conditioner at full power, close the windows and sunroof. As the interior cools down, reduce the power of the air conditioner.

Video - why you should ventilate the interior before turning on the air conditioner in your car in the summer:

2. Do not direct the flow of cooled air towards the driver, passengers and, especially, children. This is how you can get colds. The most dangerous are hearing damage.

3. Long interruptions in the operation of the air conditioner should not be allowed. The refrigerant in the system is mixed with a special lubricant. During operation of the air conditioner, oil lubricates the friction elements of the compressor, wets the oil seals and gaskets. This increases their service life and prevents cracking and corrosion processes. If the car is parked for a long time in winter, it is necessary to periodically (preferably at least 2 times a month) perform the following procedure:

engine starting;
heating it to a temperature of at least 50 degrees Celsius;
warming up the interior for about 10 minutes;
turning on the air conditioning system at medium power.

4. If the car's air conditioning is turned on in air recirculation mode, you should not smoke inside. The smoke, settling on the evaporator radiator, turns into a mixture, which will then emit a not entirely pleasant aroma.

5. Turn off the air conditioner a few minutes before the end of the trip. Next, it is better to start the stove for a couple of minutes and blow through the ventilation system at maximum speed. This operation will remove condensation and prevent mold formation.

6. It is not recommended to turn the air conditioner on and off during short trips, for example, to nearby stores.

Lada Priora (VAZ)

Just a few years ago, one could only dream of buying a VAZ car with such a benefit of civilization as air conditioning. Today you won’t surprise anyone with a Lada Priora car with air conditioning. The concerns of Priora owners have shifted from the area of grumbling about the lack of climatic comfort to issues of operation, changing filters and repairing air conditioners.

Any Russian new car must go through 5-10 years of operation before it begins to meet its main advantage - maintainability. Therefore, at first it is not easy for the happy owners of a Lada Priora car. The Lada Priora's air conditioning can be included immediately in the package, or can be installed independently after purchase.

By the way, AvtoVAZ began equipping its cars (Lada Priora and Kalina) with air conditioners and climate control units quite recently, and here the potential buyer is concerned with a logical question - what kind of air conditioner is on the Priora, who is the supplier of this rather complex equipment, how does the air conditioner work in the Priora, what are the forecasts its reliability.

So, the Lada Priora comes with one of two air conditioning options - Taiwanese Panasonic or Korean Halla. Both the Panasonic (Panasonic) Lada Priora air conditioner and the Halla Priora air conditioner are entirely, including such parts as a radiator, a refrigeration unit (with a compressor, receiver and evaporator), a control unit, air ducts and others, developed by contractors. Visually, for the car owner, the air conditioning systems differ from each other only in the appearance of the compressor; the quality of their work, according to reviews, is equally good.

To change the air conditioning filter in Priora yourself, you need to consider several points:

Firstly, the fact that the cabin filter for Priora is different for each air conditioner model (Halla or Panasonic).
Secondly, replacing the Priora air conditioner filter will be a much easier task if you have electrical circuit diagrams at hand, including a Priora air conditioner circuit diagram. The same nuances apply to the Priora air conditioning belt.

You can buy a suitable model from domestic manufacturers specializing in the production of automobile air conditioners.

It is, of course, better to install an air conditioner on a Lada Priora at a company service station, or seek help from a specialized company (although craftsmen install it themselves to save on installation costs). One thing is certain, installing an air conditioner on a VAZ Priora will pay off handsomely, delighting the driver and passengers with comfortable travel. Still, one of the points that equates the Lada Priora with an imported car is its air conditioning. Reviews from patriotic drivers largely support this statement.

More detailed information about the installation and operation of air conditioning (climate control) on a Lada Priora car can be found in the electronic repair and operation manual for Lada Prora.

It also happens to me occasionally, Panasonic condo

Why might the air conditioner turn on? I only found out that there is nothing else specifically for drying the air and blowing the windshield

This kind of garbage also happens occasionally, the air conditioner also turns on automatically. But it happens that it does not turn on automatically. I can’t understand it myself.

Yes, exactly the same as yours, but for some reason my LED lights up green.

Differences in assemblies, maybe in your generation they installed a different one. I’m not gloating, but I’m glad that not only one has this problem, it means it’s a factory jamb. It remains to figure out how to fix it with minimal losses, I think this is the main goal.

And when you turn it on again, do you get this crackling noise again? or is it already disappearing?

again, the air conditioner seems to be turned on, turns off after pressing the button. To reduce this grinding noise, I press the air conditioner, turn off the heater speed, then turn it back on.

My air conditioner automatically turns on only once and with this bang. When you turn it on again, it no longer turns on automatically and there is no such crackling noise.

Well, in general, it remains to understand why it turns on, how to eliminate it. I think that the crackling is from the gear motor, consider the damper in the heater position, but here you need to blow it out with cold.

Let's wait for people who have encountered this.))

This happens to me occasionally when I change the direction of air flow.

Where is the cracking coming from? Try installing a different control unit, see how it goes.

I think the crackling noise can only come from the motor. Let me remind you that the problem manifests itself in the cold season. I suspect that the buzzing can be eliminated by eliminating the problem of starting the air conditioner.

What is meant by the word motor? Heater motor or gear motor?

I think it’s the heater, although if you look into it, it looks like it’s not a gearbox. I’m afraid that because the air conditioner is starting, the damper switches to cold, or doesn’t want to switch, hence the grinding noise. It remains to find out what the hell starts the air conditioner, I believe that it’s in it that's the whole reason. I'm looking for people with a similar problem, or rather those who solved it!

You can determine the location of the sound more precisely. Either a heater motor on the right, or a flow reducer on the left, or heat and cold on the left outside.

The new Priora is a luxury car. The luxury package must have air conditioning. A description of the Priora heater has already appeared many times, but the fact is that the presence of an air conditioning system in the car places special demands on the stove, and therefore the Priora heater equipped with air conditioning is very different from the standard one. This article will tell you about these differences and features of the replacement.

Priora stove diagram

What is included in the heating system

The heater is located in the engine compartment in the area of the right windshield trim. It is attached to the front panel. The entrance to the heating system is occupied by a filter, which is responsible for cleaning the air used for heating and ventilation.

The design of the Priora stove consists of a number of elements:

filter cover;
filter, which is used for heating and ventilation;
heater housing;
micromotor gearbox;
radiator;
additional resistor on the fan;
fan.

Principle of operation

In addition, the Priora heater device includes important components, without which normal operation of the stove would be impossible. These include the following mechanisms:

The operation of the control unit is based on turning the knobs, each of which is responsible for one or another system parameter.
The cabin temperature sensor allows you to maintain the required temperature at a constant level. This mechanism is located in the headliner trim.
The additional resistor is located in the fan housing along with the fan, radiator, filter and damper.
The radiator is connected through hoses to the system that cools the engine. During vehicle operation, coolant circulates from the engine to the radiator all the time. The heater is controlled by a damper, which changes the direction of outside air, directing it towards or past the radiator. The damper can be located in an intermediate position, which provides for the division of the external air flow: one part is directed to the radiator, and the other passes past it.
The micromotor is responsible for controlling the movement of the damper. It is located on the left side of the body. The micromotor gearbox has an output shaft, which is connected to the axis on the damper.

This is exactly the design of the Priora stove (2010). But we have not yet considered all working issues.

Air flow distribution

As mentioned earlier, the heated air is distributed throughout the entire cabin, rather than blowing at one point. This heating turns out to be more efficient. Such heating features are provided for by the design of the Priora heater. The following elements are responsible for performing these functions:

air ducts from the side deflector and glass blower;
air distribution housing;
flap;
damper gear motor;
air duct for blowing feet.

The air distribution housing and air ducts are mounted behind the instrument panel. Inside the air distributor housing there are dampers that are responsible for changing the direction of air flow. The rotation of the dampers is the result of a gearmotor, which is located on the air distribution housing.

When the car is moving, air enters the cabin under high-speed pressure. For this, holes are used that are located in the wind window trim on the right. To make the air flow more powerful and independent of the speed of the car, a heater fan is provided. The electronic fan motor can operate at four speeds.

Air Conditioner Installation Guide

Before you complete this task, you need to decide which option you will use. There are quite a lot of manufacturers of air conditioning units on the market today, so the purchased unit must meet the requirements and characteristics of the car. The device must have a long service life, resistant to vibrations that are typical for cars used to drive on our roads. It's no secret that our car enthusiasts are more inclined to trust Conder cars and products in general from foreign manufacturers.

Does fuel consumption increase with air conditioning?

In order to drive air inside the device, cool it and release it outside, you need to take energy. What contributes to energy production? Of course the engine is running. The harder it works, the more devices can receive stable “recharge”, and, accordingly, the higher the engine consumption becomes.

Initially, Lada is not ready for the air conditioner to operate, so it has to use additional resources in the form of fuel. Consumption from 100 km increases by 1 liter. By the way, to be fair, we note that the dynamics of the car do not decrease.
