Electric heater fan Lada Kalina

Procedure in case of extraneous noise from the heater fan on the Lada Kalina

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.

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:

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.
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.

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:

First, turn off the power to the on-board network by disconnecting the battery terminals.
Drain all coolant and remove the cabin filter.
After unscrewing the fastening nuts, lower the steering column to its lowest position.
Release the brake light switch from the wires, unclip the clips, and remove the upholstery from the pillars.
Unscrew the screws and remove the front panel (cladding), then remove the dashboard along with the deflectors.
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.

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.

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.

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.

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.

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.

Determining a malfunction in the cooling system

The first sign that something is wrong with the cooling system is a decrease in the level of antifreeze in the expansion tank. The amount of coolant should be constantly monitored. In a working system, its level should be maintained between the minimum and maximum marks. If the amount of antifreeze begins to decrease, the engine will heat up faster and the risk of overheating will increase.

On Kalina there is no engine temperature indicator, there is only a light on the instrument panel that signals the critical temperature of the coolant. If you have to add antifreeze frequently, you should look for the leak. If the hoses are broken, they can be replaced, just like the clamps.

The next thing to check is the circulation of coolant in the system. After starting the engine, you need to pay attention to the expansion tank. Impaired circulation may be caused by a faulty water pump (cannot be repaired) or a clogged cooling system - in this case it needs to be cleaned.

To diagnose the thermostat, you need to start and warm the engine to 70-75 ° C, then touch the lower radiator pipe. If it is cold, the coolant circulates only through a small circuit due to the thermostat valve being stuck in the closed position. This device is replaceable only.

If after a full check the fault is not found, the cause of the stove malfunction is an air lock. After removing excess air, the heater’s operation returns to normal.

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.

Replacing a heating radiator on a Lada Kalina

Before proceeding with disassembling the heating system, you should stock up on everything necessary for repairs. Here's what we need:

new furnace fan;
Phillips screwdriver;
small pliers;
set of sockets and ratchet.

Sequencing

Before starting work, it is necessary to do several preparatory operations. First, you need to let the car engine cool down properly. Secondly, you need to remove the negative terminal from the battery.

To get to the heating fan, you will first have to remove the air filter. It is held on by two bolts, which are unscrewed with a ratchet.

The most convenient way to remove the cover of the Kalina air filter housing is with a ratchet wrench

The expansion hose pin is removed with pliers

To remove the plug, you need to press the bottom latch of the sensor with your finger.

The clamps on the injection pipe are loosened with a flat screwdriver

No tools are required to remove the adsorber

Unscrew the nuts securing the air intake with a 10mm socket placed on the ratchet

To remove the fan from the niche, the pipe located to the right of it will have to be slightly moved

Replacing the fan speed resistor on a Lada Kalina

Before starting work, you should say a few words about why a car owner might need to change the high-speed resistor on the heater. It's simple: this resistor is responsible for the fan rotation speed.

The heating resistor is responsible for the rotation speed of the Kalina stove fan

If at some point the driver discovers that the furnace fan is always running at the highest speeds and does not react in any way to the position of the regulator, it means that the speed resistor has failed and needs to be replaced, since this device cannot be repaired.

Replacement sequence

There is nothing difficult about replacing the resistor. The driver will have to perform only three actions.

There is a rectangular plug on the storage shelf of the Lada Kalina. It must be carefully pryed from below using a flat screwdriver and removed.

Under the plug there is a Kalina fan resistor

To remove the resistor, you need to disconnect the plug from it.

After removing the plug, the resistor is removed manually
