What to do if the VAZ-2109 stove fan does not work

A stove in the interior of a VAZ-2109 car is necessary in winter. Therefore, if for some reason its fan stops working, the car owner begins to seriously worry and takes all actions to solve the problem. This article will discuss the reasons for the failure of the VAZ-2109 stove fan and methods for identifying them.

Content

The VAZ 2107 stove is located in the cabin and is attached to the partition of the power unit compartment with four studs. The place where the stove connects to the body is sealed. The stove kit includes a fan casing, a radiator casing (with an air supply cover), and a fan casing (with an air distributor cover).

If necessary, the supplied air is heated by a liquid radiator. The latter is equipped with pipes for air supply and exhaust. They are supplied to the engine cooling system. A fan is mounted directly under the radiator. The electric motor, equipped with an impeller, is mounted on two elastic pads. The fan can operate in two speed modes. A special switch is located on the central panel.

Using deflectors, air is directed not only into the car interior, but also onto the side and windshields. Despite the fact that everything seems to be well thought out, the standard stove of the VAZ 2107 causes a lot of complaints among car enthusiasts. Among the main problems that owners of “Sevens” face are the following:

weak airflow in the side deflectors;
lack of airflow and heating for rear passengers;
insufficient air flow;
noise when the stove is operating.

And this is not the entire list of problems that owners of this model face. Some experts recommend installing a stove from the eighth model (while leaving the original impeller). But such manipulations can only partially solve the problem. You will only be able to achieve a slight improvement in the air flow into the cabin. At the same time, the noise will also increase.

In general, this is not a very suitable option. Therefore, we recommend making changes to the standard “Seven” stove (by installing a complete volute). Also, we advise you to modify the lower part of the stove in order to accommodate the snail and obtain a more uniform flow in different directions.

Checking the functionality of the heater elements

The first step is to test the fan. To do this, you need to turn on the ignition, and then start the fan by setting its switch to the first speed position. If it is working properly, the sound of its operation should be clearly heard. If the cabin is quiet, open the hood and listen to the sounds of the fan in the engine compartment. If the heater fan is “silent,” it means that you will have to remove it from the car and have it checked by an auto electrician, or, if you have the appropriate knowledge, check it yourself.

If during the inspection no faults were found with the fan, it is installed in place, and air still does not blow from the stove, the cause of the problem should be looked for in the wiring. It is necessary to determine why there is no voltage supplied to the terminals of the fan motor and to fix the problem. When the VAZ-21099 stove does not heat, even if the fan is working, the reason for this should be looked for in other elements of the heater.

The next step in troubleshooting is to check how well the heater air ducts are working. It is necessary to open them all, and, one by one, raise your hand to check the air flow on the windows, into the feet of the driver and passenger, and into the car interior. The air flow should be felt well. If all the heater air ducts are open and there is no airflow from them, you will need to disassemble the stove itself and look for the causes of the problems there.

What to do if the Renault Logan stove does not work. A little about the air conditioning system of the Renault Logan car - watch the video

Dear visitors of the “Cars” website! We will be very grateful for your comments on the video clip “VAZ 2109 heater fan does not work”; registration is not required for this. We also ask you to let us know if you have any problems playing the video.

Both pipes from the heater radiator are hot. Cold air blows at idle. When you raise the speed, hot air blows. What could be the problem? The heater radiator was changed, the thermostat was changed 3 pieces, the pump was new. Nine 1. 5 i europanel

In general, the problem is this: barely warm air was blowing into the middle deflectors onto the windshield, it was generally cold, I flew under the steering wheel and turned the flap all the way onto the windshield, it started blowing barely warm, hot air, and only started blowing when the speed was up to 3-4 tons. They advised me to install a thermostat with grants installed, nothing has changed, only when I gas it doesn’t blow hot, it also blows barely warm.. maybe it’s really the radiator?

15 is the same nonsense. I changed the heater radiator, the antifreeze level, the heater pipes are hot, and the air is blowing a little warm. Before replacing the radiator it was blowing hot. There was, of course, a suspicion of the tap, but the pipes were hot. It is possible that the radiator is cheap and does not have special channels inside that retain antifreeze and do not pass through quickly. What other reasons could there be? the pump is working.

salam brother I have 14 the stove works but does not heat the temperature is 70 degrees the heat should be but it does not heat what could be the reason

The filter needs to be installed on Miracle Yudo.

Hello, I make icons for videos, if you want your videos to get a lot of likes and views, then you should like my icons, I do them well, if this offer interests you, then I can send examples of my work P. S: I make icons on any topic.

He told it beautifully, but didn’t show it, and this is a video of where the pipe is, where did he put the screwdriver?

so that there are no leaves, you can stretch the stocking with hot glue to the casing

Hello guys, this is a problem, the stove operates on mode 3, what could be the problem???

reputable people sell adapters for a ten-point cabin filter and are not that expensive

I bought a new stove and installed it and everything works silently, it’s unusual

On the VAZ 21099, the car takes a very long time to heat up, and when it warms up, I turn on the fan, warm air only goes into the driver’s cabin, where the radio is located, and cold air blows onto the windshield, side windows and legs. What could be the reason, please tell me?

VAZ 2107 the stove heats but does not blow. fan is ok

THE FILTER SHOULD BE INSTALLED FROM A FINE MESH

people tell me who knows? the other day in basin 21099 the low panel heater started blowing like nothing, half that is, on the driver’s side: under the windshield, in the legs, under the side window it was warm, and everything was also cold on the passenger side, while in the center above the radio it was warm

Warm air is not supplied to the driver's side

2107

make an adapter for the cabin filter 2110 and there will be no leaves and there will be much less dust in the cabin in the summer. I took this cotton wool off, threw it in a corner, and the dust settled only after 3 minutes from it...

Well, the filter is on top of the casing. where are so many leaves from?

Why does the stove blow cold air?

If the heater radiator on a VAZ-21099 has stopped heating, most likely the coolant circulation in it has been disrupted. This problem is also caused by a number of reasons, let’s look at them:

It is quite possible that the coolant is outdated and, as a result, has lost its properties. Note that its service life is approximately five years. If during this time the antifreeze or antifreeze has never been changed, their structure begins to deteriorate with the formation of sediment, which, settling on the cooling lines, interferes with the normal operation of the system. This sediment also clogs the radiator, pipes and pipes of the heater, causing it to stop functioning normally and giving off heat. Therefore, it is necessary to free the system from the old cooling fluid by completely draining it, and then flush it using a special flushing compound. This liquid is poured into the cooling system, after which the power unit starts. The manufacturer indicates on the packaging how long it takes to use the flushing compound in the system with the engine running before draining it. After the flushing has been drained (it usually comes out of the system quite dirty), new coolant should be added in accordance with the manufacturer's instructions and the heater's performance checked. If after this the stove still does not heat, then its radiator is clogged. If, after cleaning and washing it, performance is still not restored, you will have to buy a new radiator.
One of the most vulnerable elements of the cooling system is the heater valve, which is controlled from inside the car using a special lever on the heater panel. The lever and faucet have a traction connection. It is necessary to check the functionality of the faucet. This is done like this: we move the lever, while controlling the opening and closing of the tap. If the faucet remains motionless or does not open/close completely, then the draft needs to be adjusted.
The VAZ-21099 stove heats poorly or does not work at all due to a drop in the antifreeze level in the cooling system. Because of this, air accumulates inside the heater radiator, and it practically does not function (it gives off little heat). To eliminate this, you only need to replenish the level of “cooling” in the system and constantly monitor it.
Airiness in the cooling system of the power unit is also a common cause. The carburetor has a heating pipe, which must be disconnected, since it is the highest point of the system, and accordingly, an air lock forms there. The next step is to free the system from air; to do this, remove the cap of the expansion tank and blow it out. Air will begin to escape from the hose that was previously removed from the carburetor, but as soon as coolant flows in instead, the hose must be put back in place. Air in the system has been eliminated.
The cause of the malfunction of the VAZ-21099 heater may be a failed thermostat, because of which the power unit does not reach the required temperature (90 degrees).
Failure of the pump deprives the cooling system of fluid circulation. At the same time, the engine boils and cold air blows from the air ducts. In this case, it is recommended to replace the pump.

As you can see, there are several reasons for poor operation of the stove in the VAZ-21099, and each of them is a consequence of other malfunctions.

Communities VAZ Repair and Modification Blog Bad brakes 2109

What to do when the VAZ 2109 stove does not heat well? This question is often asked by owners of cars of this model. First of all, it is necessary to understand why exactly the stove on the VAZ 2109 does not work or why it began to work poorly? There are many reasons for this.

Why does the stove on the VAZ 2109 not work?

In fact, the reasons why the VAZ 2109 stove does not work are very different. Now we will list some of the main reasons for this malfunction.

Firstly, if the fan of the VAZ 2109 stove does not work, then the heater itself will not work. The fan may burn out, in which case it should be replaced.

Secondly, it is important to remember that there must be coolant in the engine system, including in the summer. Due to the lack of liquid, the VAZ 2109 stove may also stop working

Note that the temperature of the antifreeze in the cooling system should remain 85-90 degrees.

Thirdly, if the heating system is clogged, the stove may break down; for the same reason, instead of hot air, cold air begins to flow into the car interior

Remember that there should be no contamination in the VAZ 2109 stove! That is why it is extremely important to check the heater for possible contamination before each winter, in particular tree leaves, fluff or dust can get there.

Fourthly, the radiator plays an important role in the design of the VAZ 2109 stove. To check its performance, you need to remove it from the heater and measure the temperature, for which you just need to touch the radiator with your hand. If it is hot, then everything is in order, but if it is cold, then there is some kind of malfunction in the radiator.

Fifthly, a malfunction of the VAZ 2109 stove can also be caused by a non-working cabin filter - this element cleans the interior of dust, but it significantly affects the heating system. Due to a malfunction of the cabin filter, the heater can either simply fail or start supplying barely cold air.

And finally, the VAZ 2109 stove could simply run out of antifreeze - without it, naturally, the VAZ 2109 stove would stop working.

Electric motor in the VAZ 2109 stove

The heating system of the VAZ 2109, like the heating system of any other brand of car, consists of several elements. One of the most important elements is the electric motor, so when figuring out why the VAZ 2109 stove does not heat well, you should definitely check the electric motor. What exactly could happen to him?

Firstly, the reason for poor performance of the car’s heating system may be that the electric motor of the heater has stopped working at high or low speeds. This can happen due to a blown fuse - in this case, before repairing the stove, it is necessary to replace the fuse, of course, eliminating the reason why it failed, since a similar fate can befall the new fuse.

The wires could be damaged or a break could occur in the places where the wires are connected - in this case, it is necessary to check the electrical circuit according to the diagram of the VAZ 2109 stove.

The electric motor may fail because the heating switch has stopped working. The broken switch may need to be replaced.

The electric motor itself could break down; in particular, the brushes could become stuck, the connecting wires could break, or the armature commutator could become dirty or oxidized. It is necessary to clean the commutator, eliminate stuck brushes or restore connections in the wires. If these methods do not help, most likely you will have to replace the electric motor.

Finally, the mounting block may be faulty or the additional resistor circuit may be open.

Secondly, if the VAZ 2109 stove does not work, you should check the rotation of the electric motor armature - perhaps it has become too slow due to contamination of the armature commutator. Also, the rotation of the armature may become too slow if there is a short circuit between the turns in the armature winding.

Thirdly, when the electric motor is running, extraneous noise may occur - this does not impair the operation of the stove too much, but it does interfere. Extraneous noise may occur due to an incorrectly installed deflector; another reason for such a malfunction is the impeller getting stuck on the deflector.

Fourthly, the additional resistor of the electric motor on the VAZ 2109 stove may overheat, which often occurs due to the wires of the electric motor of the stove being too tightly pinched.

As we already wrote above, there are many reasons why the VAZ 2109 stove does not work, and this article lists only the main ones. If you cannot find the cause of the stove malfunction yourself, then most likely it would be best to completely replace it.

How to disassemble a fan motor

If the stove fan does not work and you do not want to buy a new one, but prefer to deal with the problem yourself, you will need to disassemble the motor itself.

Unscrew the 2 fan mounting screws.
Unhook the fan itself; to do this, disengage its support.
Tear off the foam seal on the right side of the casing.
Remove the fan shroud support.
Using a screwdriver, release the plastic latches of the casing.
Using a screwdriver, pry up the 2 spring latches and unhook them.
Now you can remove the cover from the motor.
Pull out the motor, and the heater motor impeller will also come out with it; do not remove it so that the balancing is not disturbed.
Unscrew both screws that hold the brush holder.
Remove the 2 cage nuts.
Remove the brush holder.
Perform a visual inspection of the collector. If there are scratches or burns, it needs to be cleaned with fine-grained sandpaper. If there is more serious damage that cannot be repaired, replace the motor.
Reassemble everything in reverse order.

If you already have experience in repairing electric motors, then it will not be difficult for you to cope with this, however, sometimes it is easier to replace a broken motor with a new one than to suffer from repairing the old one and extending its life for a very short time.

Negative aspects of installing an additional stove in the cabin

An increase in the heat capacity of the cooling system entails slow heating of the coolant.
The characteristic noise of the stove in the cabin will be added, since now there will be two of them working.
The air flow from the stove will raise dust from the interior.
In the warm season, hot hoses under the floor covering will additionally heat the interior of the car, but there is a way out of this situation - install a tap in the engine compartment when making changes to the cooling system.
If you do not install another heater regulator and heat dissipation to the side, then there will be no uniform heating, but only one part of the interior will become very hot.

Installing a second heater radiator on a VAZ-2109 will be advisable only in areas with very low temperatures in winter, where the basic heater, despite its proper operation, does not cope with the task and the car does not warm up properly.

Heaters old and new

Finally, we note that the VAZ-21099 of different years of production used heaters with certain design features that related to the angle of the radiator and the location of the main damper.

In so-called old-style stoves (on cars before 1998), the radiator was installed almost vertically, and the main damper was located under the heat exchanger. There was a partition between the rear wall of the case and the radiator, which formed a channel that provided air supply down the case.

When the damper was open, the air flow moved through the radiator, where it was heated and supplied to the air ducts. In ventilation mode, the main damper closed the heat exchanger, forming, together with the front wall of the housing, another channel through which the flow went directly to the air ducts.

In the new model stoves (on cars produced since 1998), the radiator position angle was significantly smaller than on old heaters, which is believed to provide a larger contact area of the air flow for heat exchange.

The position of the main damper and its shape also changed (it became arched). It began to be located above the radiator. In the closed position (ventilation mode), the damper ensures air movement along the shortest path to the air ducts. In heating mode, it blocked the cold air supply channel to the air ducts and directed the flow down the housing, from where it went to the heat exchanger.

Heating of the interior of any car is provided by air, which is heated in the heater radiator. The VAZ 2109 heater radiator is connected in parallel to the main radiator, which is part of the cooling system of a car engine.

The heater itself is secured with four nuts in the passenger compartment under the instrument panel to bolts that are welded to the air supply box. The air heated in the heater is directed through an air duct system into the passenger compartment. The air ducts are attached to the instrument panel from below and sealed with gaskets.

How to use the stove

It is no secret that its service life and reliability of operation largely depend on how an item is handled. This is perfect for a car heater. The more correctly you operate it, the better and longer the stove will be able to work.

There are a few simple rules that, if followed, will extend the life of this unit.

During cold weather, control the stove in two modes. First, start the car, set the control to “All on glass”, and while driving, switch to directing the heat to your feet.
Do not block the air supply nozzles.
Carpeted interior floors will require you to aim the nozzles higher.
Try to always keep the glass clean.
Use air conditioning in damp weather.

Main stove malfunctions

As we have already mentioned, the stove is connected to the internal combustion engine cooling system. Accordingly, heating problems may arise for the following reasons:

Insufficient amount of coolant in the system.
Clogging of radiator tubes.
There are air pockets in the system. To eliminate them, you will need to unscrew the cap of the radiator or expansion tank and let the engine idle for a while.

There are a number of cooling system malfunctions that can also affect the performance of the VAZ-2109 heating system. We look at the most common ones.

The weak point of the heating system is the valve through which antifreeze enters the heater radiator. This unit may leak. In this case, it must be replaced with a new one.

Poor quality coolant causes damage to rubber pipes due to its aggressive chemical composition.

Check the condition of the pump, which is responsible for pumping antifreeze and circulating it in the cooling system.

Poor operation of the stove can be caused by incorrect operation of the electric motor that drives the heating system fan.

If you notice extraneous sounds in the operation of this motor, this is a signal for a number of problems:

Possible overheating due to fuse failure.
When operating at low speeds, warm air does not flow - the electric motor has failed or there has been a break in the electrical circuit of the heating system.

Check the condition of the heater core regularly. It can become clogged during operation, and this provokes an insufficient supply of antifreeze. To carry out preventive work, you need to dismantle this element and wash it. If the part cannot be cleaned, then it is better to buy a new one and replace it.

Experienced car enthusiasts claim that the problem of poor operation of the stove may be a loose fit of the damper. Because of this, cold air from the street enters the cabin, and warm air goes to the feet. To solve this problem, just adjust the damper using a special control lever. It is located next to the gas pedal. Use pliers to tighten the cable that goes to the damper. Make two turns around the head of the bolt that secures the cable to the control arm.

If these steps do not help solve the problem, then inspect the joints of the pieces of foam rubber or plastic. Perhaps cracks and gaps have formed there. You can solve the problem with the help of sealant or simply change the insulation.

VAZ 2109 Troubleshooting the heater fan - Samara. Body and heating system

The VAZ 2109 stove fan forces air into the cabin. Due to this, in the winter the interior heats up faster, and when it’s warm outside, the air flow saves the windows from fogging up. Therefore, fan malfunction causes great inconvenience and affects safety.

Causes of stove fan malfunction

If the air from the stove begins to blow with less force or there is no flow at all, it means the fan is broken. The driver may also be informed about the failure of this spare part by an unpleasant cracking sound that appears after switching on. In any case, to understand the problem, the fan must be removed. Most likely, the VAZ 2109 heater fan will need to be repaired or replaced.

How to remove the stove fan VAZ 2109

The heater fan is located under the hood, between the passenger compartment and the engine. It is hidden in a plastic case. Removing the VAZ 2109 heater fan must be done in the following sequence:

First of all, you need to open the hood and remove the terminal from the battery.
The fan cover is secured with four screws. They need to be unscrewed with a Phillips screwdriver and the casing removed. To do this, you need to spread the walls to the sides.
The fan itself is also secured with screws. They need to be twisted and the grille removed.
After that we go to the salon. You need to remove the positive wire from the connector. This will release the negative wire, which is secured to the stud.
Next, unscrew the nut that holds the motor and remove the ground wire from the stud.
Now you can take out the fan itself. You need to lift it a little, turn it 90 degrees and pull it out.

Removing the fan can be problematic due to the “corridor” being too narrow. In this case, you can pull back the stove box, thereby expanding the path for the fan.

Important! When working with wires, you are often tempted to use wire cutters. This should not be done, since twisting with a wire is not reliable. After this, you can proceed directly to repairing the fan of the VAZ 2109 stove

How to disassemble the VAZ 2109 stove fan and determine the malfunction

Once the part has been removed, you can disassemble it. This is the only way to determine the problem, so you need to stock up on a set of tools and patience. If there is a diagram of the VAZ 2109 stove fan, then it will also not be superfluous.

To disassemble the fan, do the following:

Remove the foam from the joint. It is necessary to seal the connection with the body. When subsequently assembling the fan, it is necessary to use a new foam, attaching it with a universal one.
Remove the rubber cushion.
Separate the casing halves. To do this, you will need a flat-head screwdriver, with which you need to press out the plastic retainer.
Next, remove the plastic cover. It is held in place by two clamps. They also need to be pressed out with a flat screwdriver.
Once the cover is removed, the fan motor will become accessible. It can be pulled out without any effort.
The first thing to check is the impeller. But you should not dismantle it if no mechanical damage is detected. Removal will result in imbalance. If damage is found, you should contact a specialized workshop. Most likely, the VAZ 2109 stove fan will need to be replaced.
If everything is in order with the impeller, we proceed to removing the brush holder. To do this, unscrew the two screws that secure the part, remove the cage nuts and remove.
We inspect the brush holders. If the car has a good experience, then most likely they are worn out or damaged. In this case, they need to be replaced with new ones.
By removing the brush holder, the springs will be accessible. Their status also needs to be reviewed. If the springs are deformed or stretched, they must be replaced.
After this, you can assemble the brush holder.
The last thing to do is check the condition of the commutator armature. It may form carbon deposits. It can be removed with polishing paste. If scratches are found, they need to be removed with sandpaper or replaced.

Quite often leaves and other “foreign bodies” get into the fan. If they are found, they must be removed. It is quite possible that they were the cause of poor fan operation or crackling noise.

After this, you can begin assembling and installing the fan. All steps should be carried out in reverse order. If, after installing the fan, it does not work, it is better to take it to a specialized workshop. The craftsmen will repair the VAZ 2109 stove fan or offer to replace it.

High panel

Replacing a high panel heater core consists of the following steps:

The heater radiator is located where the front passenger's feet are. That is why it is advisable to remove the passenger seat during the work.
Find the bolts on the right side that secure the panel, and then unscrew them.
Next, you need to slightly pull the body towards you and insert a spacer in the form of a wooden block into the gap.
Then you need to turn off the tap and place a few rags in places where there may be a leak.
Then you need to open the hood and the expansion tank cap on the radiator.
The stove is located between the glove compartment and the lower shelf. All work must be done quickly so that the antifreeze does not spill. Also, in order for the hoses to go towards the radiator, you will need two rubber gloves.
Then we prepare a rubber plug and put our hands through the allocated panel to the radiator.
We remove the lower pipe and plug the hole with the thumb of our left hand, and then insert the plug into the hose with our right hand.
After this, you will need an empty cooling water container. It must be placed under the pipe.
Exactly the same operation must be repeated with the upper pipe.
When the coolant has drained, you need to remove the heater core and install a new one. When removing the radiator, lift it up, move it slightly, and then pull it down.

The procedure is not easy, but if you follow the rules, you can do it yourself, without turning to specialists. There are many videos on the Internet on this topic that will help you quickly and efficiently replace the interior heating radiator.

So, let's start refining the stove

From the very beginning you need to deal with the cable that opens the stove tap. Typically, it is quite long and does not open the faucet all the way, so the stove does not heat at full capacity. To eliminate this problem, simply cut the cable either from the side of the regulator or from the side of the faucet itself.

Heater valve cable

Try checking the fan operation. It is located in the middle of the bath under the hood, and is covered from water by glass and a casing. Manufacturers cover the air intake hole with paper for some reason. This distorts the air flow and damages the fan itself, so it is better to remove them immediately.

Next, check how strong the air flow is on the VAZ 2109. A fairly common problem is that the bearings that spin the fan itself fail. If in doubt, it is better to replace it immediately. This is quite simple to do, and the bearing will cost you only 500 rubles.

The problem could also be in the fan itself. When replacing a fan with a 2109, it is better to choose only an original unit with high performance. Often, such a fan not only produces a strong air flow and consumes significantly less energy.

fan replacement

You can change the fan following this diagram:

Open the casing that covers the fan;
Carefully unscrew the bolts that secure the fan;
Then you need to disconnect one positive connector under the front panel on the driver's side and unscrew the ground on the wires that go to the fan;
The fan needs to be turned several times so that it moves to the right side of the bath, where it can be easily reached.

Next, rinse and vacuum the stove, try to wipe it as carefully as possible. We make the connection in the reverse order. At the end, carefully seal everything with sealant so that no dust or moisture gets inside.

Often following such a scheme is enough to significantly improve the operation of the stove. But if you still want to achieve an even better result, then you can try several more options for tuning the heating system.

https://youtube.com/watch?v=F6QkZ73PsuI

Another way to modify the stove is to shorten the cable that turns on the stove lever. Often it is quite long and does not turn on the heating at full power. Just shorten it a little, and there is a possibility that the car will become warmer.

You can also install another heater. It can take air either from a stationary stove or have a separate fan of its own. But such tuning is not always effective.

You can also install additional electric heaters, and their number is unlimited. This should be done according to the diagram. But do not forget that they consume quite a lot of electricity. Although, on the other hand, they can be powered from a separate generator, which is located in the trunk.

As a tuning option, you can try sealing the air valves. The scheme is as follows: you need to thoroughly seal the places where the valve is pressed with good quality foam rubber, soft rubber or a springy seal for any purpose.

We insulate all joints and channels

Modification of the VAZ 2109 thermostat and connection diagram. In order to tune the thermostat, you just need to replace it from 5-hole to 6-hole. The usual size of the bypass channel on a 6-hole thermostat is 11 mm, and on a 5-hole thermostat it is 16 mm. But regardless of which thermostat you have installed, the coolant flow can be easily adjusted. After such tuning, your stove will work much better even at idle speed.

Using an aluminum pad, you can independently adjust the bypass diameter within the range of 4 to 6 mm. Using this scheme, you will slightly increase the warm-up time of your VAZ 2109, but the interior will become much warmer than before.

From all of the above, we can conclude that from an ordinary standard stove, with the help of tuning, you can make a fairly powerful heating device that will prevent you and your fellow travelers from freezing.

Operating principle of the furnace system

As soon as the temperature outside the window drops below zero degrees, coolant in the car begins to flow directly through the furnace tap. After the engine warms up to the optimal temperature (about ninety degrees), antifreeze will begin to flow into the radiator.

Inside the car there is a special lever on the panel that is responsible for turning on the ventilation system. In the VAZ 21099 it is equipped with three power modes. You can also select the direction of the air flow. The air is directed using shock absorbers located at different points in the car.

Formula 1 style side mirrors

These non-standard side mirrors first appeared on Formula 1 racing cars and immediately attracted the attention of car enthusiasts. f1 models are intended for those who:

energetic and prefers a sporty style,
strives for individuality in everything;
ready to improve the aerodynamic properties and change the appearance of the standard nine with the help of tuning (from English - adjustment, tuning).

Advantages	Embodiment
The f1 side reflectors differ from the standard ones in their lightness.	This is expressed not only in their properties, but also in their minimalist design.
F1 are produced on a thin but durable metal leg.	They are made of shockproof glass that can withstand significant loads.
Mirror devices f1 are universal in the sense that they can be installed with equal success both on a foreign car and on the oldest car of the Soviet automobile industry that still runs on our roads. They are also easy to install on the “nine”.	No adapters are required for installation. The f1 base is mounted either to the body or to the door pillar. Where there are mounting platforms for mirrors - to the platform itself.

In order for the trip to be safe, the driver must have sufficient visibility and not only see what is happening in front and behind, but need to have an idea of what is happening on the sides of the car. This is necessary when performing various maneuvers, such as changing lanes, overtaking, entering the road, reversing, etc.

The standard mirrors of the VAZ 2109 cannot provide sufficient visibility, they have a rather narrow range of adjustments, they are easily splashed with dirt, and in cold weather they are immediately covered with an ice crust. The stores have side mirrors that are equipped with electric heating and turn signal indicators. Installation does not require large expenses and, if desired, you can install the mirrors yourself. During installation, we will have to dismantle the front door trim of the car and remove the control handle for the standard VAZ 2109 mirror, if it is still intact. Use a thin flat screwdriver to pry it off and remove the inner lining of the mirror. Next, take a Phillips screwdriver and remove the three screws securing the base mirror. Now nothing prevents us from removing it. To install new mirrors, we cut out a special marking template, which is included with the new mirrors. We apply this same template to the door and use an awl to transfer the markings to the door. Now take a round file or cutter and increase the diameter of the hole. We lay a wiring harness through the corrugated casing from the door into the passenger compartment and make the connection parallel to the rear window heater.

All these actions are indicated in the attached manual, so it will not be superfluous if the instructions are before your eyes. We hold the side mirror with one hand, and with the other we fasten the mirror adjustment mechanism; fastening is carried out with a screw, under which a large washer is inserted. Next, we install the internal lining in its regular place and tighten the three self-tapping screws that secure the mirror. Keep in mind that the top screw goes through the hole in the mirror adjustment mechanism. The next step is installing the mirror control knob. If the previous one was broken, as most often happens, we replace the part with a new one, which is available in any specialized store. Use the handle to adjust the position of the mirror. The second mirror is installed in the same way. We turn on the heated rear window, thereby checking the operation of the heated side mirrors, this should take several minutes. If the kit includes turn signal mirrors, you need to attach a special plate to the outside of the door (the plate is included in the kit), take an awl and make a marking, in this place you will need to drill a hole for attaching the mirror. The wiring runs from the door to the salon, we connect them in parallel to the turn signal of the VAZ 2109 car. We put the mirror in its regular place and tighten the screws for its fastening. If you overtighten the screws, the plastic bosses may crack. To prevent this from happening, we put pieces of a thin-walled metal tube of the appropriate diameter on them.
