The stove does not work on the Lada Kalina (reasons and repairs)

How to check the operation of the Lada Kalina stove

We carry out all actions with the engine running. Before checking the heater, study the diagram and structure of the Lada Kalina stove.

Checking the ventilation and heating system fan:

1. We set the air temperature regulator knob on the control unit to the extreme position of the blue sector.
2. We alternately switch the fan speed knob, starting with the first speed and ending with the fourth.
3. We check the intensity of the air flow coming from the air ducts. It should get stronger with each switch.

If the heater does not work on the Lada Kalina, check the integrity of fuse F5, as well as its power circuit. If the fan does not operate in all modes, or the air flow intensity does not change linearly, check the additional resistor and switch. If the air flow is weak, replace the cabin air filter.

Checking the stove dampers:

1. Set the temperature regulator to the extreme position of the blue sector, and the fan speed to maximum.
2. We turn the damper control knob on the block and at the same time monitor changes in the directions of air flows.

Unchangeable air flows indicate a malfunction of the mechanical heater control unit (the draft has flown off, or does not screw onto the roller due to its breakdown), or the damper is jammed. If the car uses climate control, then check the damper micromotor and the ventilation, heater and air conditioning control unit.

1. Warm up the engine to operating temperature.
2. Turn the air temperature regulator to the extreme position of the red sector.
3. Warm or hot air should come out of the air ducts

If the air temperature has not changed, check the serviceability of the mechanical heater control unit (the rod has come off, or does not screw onto the roller due to its breakdown), or the damper is jammed. If the car uses climate control, then check the damper micromotor and the ventilation, heater and air conditioning control unit. Make sure the engine cooling system is working properly.

Checking the interior temperature sensor:

The interior temperature sensor is installed in the lampshade on cars equipped with a climate control system. Most often, a sensor malfunction can be determined by the operating mode of the stove. If only hot or cold air blows from the panel nozzles, regardless of the position of the handle on the heater control unit, then most likely the ceiling air sensor has failed.

Engine cooling system problems?

Most often, problems with the stove arise due to the EDS (engine cooling system). The first step is to check the coolant level in the expansion tank and, if necessary, add it to a level between o and “MAX”. By the way, many car enthusiasts in winter specifically add coolant only to the “MIN” mark; the less liquid there is in the system, the faster it will heat up, and therefore Kalina’s stove will start blowing warm air a little earlier than usual.

If coolant has to be added all the time, then the cooling system is leaking somewhere. You should carefully inspect all pipes for leaks, and also tighten the clamps. If the stove (radiator) is leaking, then it should be replaced.

Now you should check the circulation of antifreeze in the system, paying attention to the expansion tank.

If there is no circulation of coolant, or it is insufficient, then there may be two reasons for this ailment: the pump (it should be replaced) or the ODS is clogged (needs to be cleaned).

We check the thermostat: warm up the engine to 75 degrees and touch the upper radiator pipe (in diagram No. 6), if it is cold, then the antifreeze is circulating only in a small circle, the thermostat should be replaced with a new one.

Another reason that Kalina’s stove does not heat is the air in the SOD. Read how to remove air from the engine cooling system. More details about how to repair Kalina's SOD.

A couple of useful tips

Have you noticed that the heater on the Lada Kalina blows cold? Proceed according to the scheme “from simple to complex”, first check the simplest elements of the heating and ventilation system, for example, the air filter and the presence of coolant. Then gradually move on to more complex design details.

Another good way to find out which part has failed is to replace it with a known working part and check the operation of the system. And you don’t have to buy a new spare part if you borrow it from a friend. You can also try to negotiate with the seller in the store, take a new part for testing, leaving a deposit.

How to independently change the heater fan in a Lada Kalina car

If the car interior is left without heating in the cold season, this does not bode well for either the driver or his passengers. This rule applies to all passenger cars, and the Lada Kalina is no exception. In general, the heater in this car is quite reliable. But it has one weak point: the furnace fan. It is this part that most often fails and becomes a source of real headache for the Kalina owner. Is it possible to replace the stove fan on a Lada Kalina yourself? Can. Let's figure out how this is done.

Statistics of malfunctions of the Lada Kalina stove

According to the results of the survey “ Why does the stove heat poorly on the Lada Kalina? » the main causes of the malfunction were identified:

1. 32% voted for problems with the heater damper.
2. 14% of votes were given for a faulty heater fan.
3. The same number of votes (13%) were given for a failed ventilation and heating system control unit and a faulty heater radiator (replacement).
4. For 9% of survey participants, the fault in the heater’s malfunction was the damper’s micromotor reducer.

The remaining votes were given for other problems with the Lada Kalina stove: a faulty additional resistor for the stove, a cabin temperature sensor and a dirty cabin filter.

Let us remind you that you can find various modifications to the car systems in the Lada Kalina tuning section.

The car's heater is used very actively, especially in cold weather. Very often, after a long mileage, when you turn on the heater, an annoying whistle is heard, which disappears after turning off the fan, so it becomes clear that the problem is not in the stove itself, but only in the fan.

You will learn what to do if the heater fan on your Lada Kalina whistles in our article. In most cases, when a whistle appears, the breakdown can be fixed, and in more than half of the cases this can be done independently.

DIY heating system repair

To change this or that part of the heating system, it is not at all necessary to seek help from specialists. This will help save time, but not money. If you follow the recommendations, you can replace some system components yourself.

Heater fan

Even beginners can replace the Kalina stove fan. The main problem is its location. For this reason, most of the time is spent not replacing the part, but dismantling it.

Fan replacement with panel removal

The method is recommended by AvtoVAZ engineers, but it is not the simplest. Not everyone decides to use it in a regular garage. When performing work, you must follow the instructions:

1. First, turn off the power to the on-board network by disconnecting the battery terminals.
2. Drain all coolant and remove the cabin filter.
3. After unscrewing the fastening nuts, lower the steering column to its lowest position.
4. Release the brake light switch from the wires, unclip the clips, and remove the upholstery from the pillars.
5. Unscrew the screws and remove the front panel (cladding), then remove the dashboard along with the deflectors.
6. Now you can begin dismantling the fan. To do this, you need to disconnect the terminal with wires from it, remove the ventilation hose, and unscrew the fastening nuts.

After installing the new fan, all further actions are carried out in the reverse order of dismantling. The procedure requires attention and accuracy and takes a lot of time. At some points, the help of a second person will be required.

Replacing a fan without removing the panel

It is not practical to remove the entire dashboard just because of the heater fan. You can replace the device without removing the dashboard - you just need to lift its right side. Next, you should “arm yourself” with a knife and a flashlight and crawl under the panel. The noise insulation is cut off, the fasteners are unscrewed, and replacing the Kalina stove motor becomes much easier. This method will significantly save time and nerves, although it will create some inconvenience.

Before you start replacing the electric fan, you need to make sure that this particular device is faulty.

Replacing the temperature controller

To dismantle the part and replace it, it is necessary to remove the control unit assembly. The procedure looks like this:

• the on-board network is de-energized by removing the “negative” terminal from the battery;
• the radio tape recorder (if any) is removed, and the terminal block of wires is unhooked from it;
• the damper control lever is removed;
• Next, the handle for controlling the temperature and direction of air flow is dismantled;
• there are plugs located at the bottom of the control unit - they need to be removed and the fastening screws underneath must be unscrewed;
• the center console should be carefully pulled towards you;
• After removing the console, disconnect the terminal blocks from the switches.

After replacement, everything is assembled in the reverse order. This operation is simple and only requires a couple of different screwdrivers to get the job done.

Replacing the heater core without removing the panel

Changing the heater radiator on a Lada Kalina, as on all front-wheel drive VAZ cars, is not an easy task. You will have to remove most of the front panel. To work, you will need a new heater radiator, hoses, clamps, an angle grinder and a standard set of tools. First you need to carry out some manipulations in the engine compartment:

• drain antifreeze from the cooling system;
• remove the battery and air filter housing, ensuring unhindered access to the heater pipes;
• you need to disconnect all the rubber pipes from the stove in the engine compartment, unscrew the nut securing the metal shield that covers the hoses going to the stove into the cabin.

Now you need to go to the salon and perform the following steps:

• unscrew the three fastening nuts and remove the gas pedal;
• move the brake pedal as far as possible to the side;
• Having made a cut on the metal shield, cut off the radiator pipes with a knife;
• Unscrew the fastening screws and pull out the heater radiator towards the pedals.

Removing the radiator without removing the panel is only half the battle. It is no less problematic to install it. Before this, the pipes should be thoroughly cleaned of burrs and roughness with fine-grained sandpaper.

A hose with a thicker end is attached to the upper radiator outlet, and a narrower end to the lower outlet. The other ends, without being confused, need to be installed instead of the old ones. It is advisable to treat the place where the hoses from the passenger compartment enter the engine compartment with soundproofing material.

Replacing the stove radiator will help solve the problem of insufficient heating. Due to the labor-intensive nature of most work on troubleshooting a heating system, prices for such services at specialized service stations may seem quite high. It is not surprising that many “folk” repair methods have appeared.

Major breakdowns

Noise and whistling are already a breakdown; it is worth noting that the stove either works or it doesn’t. If there is no airflow from it at all, then most likely the motor is jammed or the brushes are worn out. And if there was noise and then at one point it disappeared and the heater stopped working altogether, this means that the motor has stopped and the bearing or bushings need to be checked.

By the way, the appearance of a noise or whistle is not always a signal that the engine is failing; it may also be that a large amount of dirt has accumulated in it and just needs to be cleaned.

Therefore, first of all, when noise appears, disassemble the heater and try to clean and lubricate it, in most cases this helps.

6p), but you will have to disassemble the engine and resolder it (not at all difficult). For me, the 2nd option took about 2 hours, taking into account the analysis for the first time.

You do this: turn the heater on to 4th speed, hit your fist in the area of ​​the heater motor in the engine compartment, the engine will purr, but very slowly, and push the brushes hard. Then to auto parts. New motor (

this is the old model, the new one is twice as expensive

Today the engine miraculously started working) apparently it was frozen after washing the car) but in the cold it worked for the first minutes with a lot of noise, I still think it’s a mess. The main thing is to survive until it warms up, and then you can get wiser. At -12, disassembling the heater is not at all easy, because even in summer it is never fun to disassemble it.

There is a chance to reach the heat))) for about a month it worked or didn’t. the last week before the death of the motor

I had to use physical force on this unit. This was in January.

Disassemble and clean the fan

The main thing is that before starting work, do not forget to disconnect the terminals from the car’s battery so that a short circuit does not occur.

There are two options for developing actions:

1. Just clean it: to understand what the problem is, you will need to spin the already removed engine; if it turns over with difficulty, sometimes even familiar noisy sounds appear, then in this case you will need to vacuum the engine and lubricate the bearings and other rotating parts. You can lubricate with any silicone grease or WD-40. Also be sure to clean all dirt from the shaft. In 65% of cases, these actions are enough to get rid of extraneous sounds from the stove and will last for a long time.
2. Repair or replace shaft bearings: To determine whether any work needs to be done on the shaft bearings, you first need to look at their condition. If they don't turn at all, then you will have to disassemble the motor. Bearings may fall apart or become jammed from prolonged operation. Of course, you can just buy a new motor and not have to worry about repairs, but a new part costs a lot and if you try really hard, you can still fix the old one yourself.

How to remove the fan on Lada Kalina

If the stove on Kalina is humming, it is already clear from what has been described above that it is simply necessary to repair or replace the fan motor. Therefore, we begin dismantling by removing the outer plastic grille and removing the cabin filter.

• Then remove all debris from the seat so that it does not fall on your head while removing the fan.
• To proceed further, you will have to remove the front passenger seat, otherwise you will need to take an acrobatic pose inside the Kalina's cabin.
• The fan runners are held on by four nuts that need to be unscrewed. Then open the glove compartment and empty it of its contents, unscrew the four screws on its back wall and don’t forget about one more on the outside, under the airflow grille.
• Remove the decorative trim from the front right pillar; under it there are two more screws that secure the plastic panel and the blower unit. You need to unscrew them, remove the blower unit and lift the plastic panel, which is held on by Velcro. Underneath you will find two nuts; you will need to loosen them using a socket wrench. Then move the torpedo as far as possible and lock it in this position.
• Sit comfortably on the floor of the Lada Kalina and remove the heater fan, while disconnecting the electrical connector. You will need to replace its turbine with a new motor or repair the old one and put it back. Then install the unit in its place and reassemble everything in reverse order.

Procedure for resuscitation of the Lada Kalina stove fan motor

• Before removing the clamp, mark the location of the impeller relative to the shaft and remove the impeller.
• After you gain access to the two bolts, you need to unscrew them and open the motor.
• Unhook the anchor lock at the top, remove the washers and pull out the anchor.
• This will give you access to the bushings.
• Clean and lubricate parts.
• At anchor, wipe and sand the contact plates with the finest grain sandpaper.
• You also need to clean the contact pads and wipe them down.
• Do not lubricate the contact surfaces under any circumstances! Everything should be sterile clean and shiny.
• Use graphite lubricant only to lubricate high friction surfaces. But under no circumstances use oil or grease for these purposes, as they will leak in the future.

Important! Do not drill holes or pour oil onto the shaft or spray WD while removing the cooling hose. This is not recommended, although you can find many recommendations on this matter on the Internet. Such actions are dangerous for the motor and can lead to its failure.

• Reassemble the motor in reverse order. Now it will not buzz and will spin without squeaks or noises.
• Reassemble all other parts in reverse order.

As you can see, the steps are not at all complicated, the main thing is not to get confused about what to screw on during assembly. If you have problems with heater fan noise, try to solve the problem yourself as much as possible. If repairing the problematic part is impossible, then replace it with a new one, and if you still doubt your abilities, seek the help of specialists.

With the onset of the cold season, the correct and uninterrupted operation of the stove in the car becomes especially important. After all, comfortable and safe movement depends on the correct functioning of this element of the car’s heating system. The stove maintains a certain temperature in the cabin. But, a cabin heater is also necessary to prevent the windows from fogging up. Unfortunately, for many drivers this device brings a lot of inconvenience.

Heating system modifications

Every owner of a Lada Kalina is faced with the need to modify the stove. The upgrade usually involves installing a new 6-hole thermostat, a coolant filter element, and a different heater valve. Many, given the mediocre performance of the pump, install an additional water pump. There are many ways of minor tuning that can be used to achieve improvements for greater comfort.

Increase in operating temperature

This method is suitable for Lada Kalina with an electronic gas pedal. Previously, the throttle valve, which was heated by a common cooling system, was controlled by a cable drive. After installing the electronics, the hose that went for heating was looped into the cooling system.

To upgrade, you will need a tee, an additional hose and clamps. The second air duct is mounted as close as possible to the thermostat - the tee is installed in the coolant supply pipe to the radiator. The other end of the air duct is connected to the outlet of excess steam near the expansion tank fitting. Thanks to such a simple modernization, it is possible to increase the operating temperature to 92-95 ° C when the stove warms up from 50 ° C and above.

Installation of a hydraulic fence for drainage

A regular medical dropper is inserted into the channel of the steam outlet tube, which is immersed in antifreeze to the bottom of the expansion tank. As the liquid cools, obeying the law of physics about communicating vessels, it will begin to be drawn into the steam outlet, preventing the possible formation of air plugs - airing. Thanks to this simple method, the stove will begin to heat much more efficiently, which means the interior will be warmer.

You can also change the clamps to more reliable ones - self-tightening ones, and ordinary rubber hoses - to silicone ones. To reduce heat losses, it is worth taping all the joints of the air ducts, but to do this you will have to dismantle the panel again. The most convenient way to do this is when troubleshooting a problem.

Regular removal and installation of the dashboard will lead to its loosening, squeaks, knocks and other extraneous sounds will appear coming from under the panel while driving.

Reasons why the stove fan stopped working

In order to understand why the stove fan stopped working, why the heater does not heat, you need to understand the structure of this system. In most cases, a car heater consists of: an automatic control system controller, a cabin air temperature sensor, and a micromotor gearbox. Often, heater repair does not require specific knowledge and skills. Most often, the cause of breakdown is dust, but if cleaning the mechanism does not help, then the cause of the breakdown can be quite unpleasant.

Common problems that cause the stove fan to not work:

• The fuse has blown. Fuse F7 with a current of 30A is attached not only to the heater, but also to the glove compartment light and the headlight washer motor. The cause of a blown fuse may be a short circuit. Therefore, if the problem lies precisely in this, then it is necessary to go through the entire circuit and look for the source of the short circuit;
• A common reason why the heater fan does not work is the radiator. Over time, scale forms in it;
• An air lock can also negatively affect the operation of the heater. In order to get rid of this trouble, you need to warm up the engine, then loosen the clamp on the hose, and then remove it so that the air can escape;
• If the stove only works when warm, then most likely the problem is in the ignition relay. In this case, the relay requires replacement. It is located under the instrument panel in the center console;
• There are situations when the heating is turned on only if the stove switch is in position 3. The way out of this situation is to replace the additional resistor. The current to the fan in position 3 goes directly, and in positions 1 and 2 through a resistor;

Purpose of the heating fan in the Lada Kalina

To understand why a car needs a heating fan, you should have a good understanding of how its heating system functions. The Kalina engine is constantly cooled with antifreeze. Having warmed up, the antifreeze from the engine goes to the main radiator, blown by the main fan. If this happens in the cold season and the driver turns on the heater, then hot antifreeze from the main radiator enters the heating radiator, which is half the size of the main one.

The Kalina heating fan is made of very unreliable plastic

The heater radiator quickly heats up with boiling antifreeze. The heat emanating from it is supplied through an air duct system to the interior of the car. And this hot air is pumped in using a heating fan, which constantly blows on the stove radiator and is driven by a small electric motor, and the intensity of heating of the interior directly depends on the rotation speed of the heating fan. Thus, without a heating fan, hot air simply cannot enter the car’s interior, and any breakdown of this device leads to the fact that the driver in the cabin begins to freeze.

Where is the heating fan located?

The heating fan on the Lada Kalina is located behind the heating radiator, which, in turn, is located under the central panel of the car, to the right of the driver. It is not possible to see this entire structure from the interior.

Air ducts and ventilation nozzles in the Lada Kalina are located throughout the front panel

To replace the heating fan, the driver will have to completely or partially dismantle the central panel. There are no other options.

Fan replacement

If the stove fan stops working, or it makes strange sounds, then it is necessary to dismantle it, clean it or replace it. However, you should not rush to replace it; first you need to make sure that the brushes of the mechanism are intact, in which case replacement will not be required. Getting to this part is not so easy, but for cars with the Lada “tenth” family design, there is a time-tested reliable way to get to the fan:

1. Release the right side of the instrument panel by unscrewing the eight screws, then the panel must be lifted.
2. Afterwards it is necessary to remove the standard sound insulation of the engine shield.
3. Next, you will need to take a position in the cabin so that your shoulders rest on the mat; this is the easiest way to reach the fan.

Removing the fan is quite simple. All you need is the necessary tools and a little time. By unscrewing the three screws of the casing cover and removing the frame of the radiator pipe seal, you can remove the device. But before changing a part, you need to determine whether it works or not.

After all, it often happens that a dismantled fan spins and functions normally, but as soon as it is put back in place, it immediately ceases to fulfill its direct duties. The reason for this is most often accumulated small particles that prevent normal contact in the mechanism.

Signs and causes of furnace fan failure

The owner of the Lada Kalina will immediately know that the stove fan has broken down. Here are the characteristic signs of failure of this part:

• the pressure of hot air blown out of the deflectors is greatly weakened and practically does not depend on the position of the stove regulator;
• The operation of the heater is accompanied by a loud creaking noise, which turns into a grinding noise when the fan speed increases.

All this happens for the following reasons:

• One or more fan blades are damaged. The fact is that the fan on the Lada Kalina is made of plastic, and this plastic is far from being of the best quality. This is especially true in severe frost. If there is a small crack on the blade, then at low temperatures it is guaranteed to increase and the blade will completely collapse. This, in turn, will reduce the pressure of air pumped into the cabin, which will immediately become noticeable to the driver and passengers by the lack of pressure in the deflectors;
• Fan squeaking occurs due to wear of the bushing on which the fan is mounted. This bushing lasts an average of five to six years, after which it will inevitably have to be replaced, since during this time it wears out almost completely (and it is advisable to install a ball bearing in place of the bushing, since its service life is twice as long).

Here we should make one digression and tell a real-life incident. As mentioned above, when replacing a furnace fan, drivers try to install them not on bushings, but on ball bearings. Until recently, there were no problems with this: you had to go to the nearest auto parts store and buy a Luzar fan. But for some time now it has become difficult to find products from this company. I don’t know what this is connected with, but the fact remains: “original” VAZ fans with hubs are on sale everywhere, but devices with ball bearings cannot be found during the day. One driver I know solved the problem in a very original way: instead of rushing around car stores, he simply ordered the required part from the Chinese online auction “Aliexpress”. The ball bearing fan arrived in the mail about a month and a half later. According to him, it cost only a third more than Luzarov's. This is probably a markup for shipping.

The ball bearing heater from Luzar is currently in short supply

About lubrication of the Lada Kalina stove fan

Lubricating a squeaky bushing on a Lada Kalina fan is a pointless task. Yes, lubricant will remove the annoying squeak for a while. But if the bushing is worn out badly, then even the thickest lubricant will very soon be used up and the bushing will begin to creak with redoubled force. Therefore, car owners prefer not to lubricate worn bushings, but to replace them along with the fans. And this is the only rational option.
