✅ How to change the heater motor on a Priora

Removing the Priora heater fan

You will need to : remove the throttle assembly and move it to the side, remove the frill and sound insulation of the engine shield.
Prepare a Phillips and flathead screwdriver. Procedure :

Bend the end of the brake pedal bracket upward.
Unfasten and cut the clamp securing the heater fan wire block.
Disconnect the block with wires from the heater fan by pressing the lock.

Disconnect the block with wires from the additional resistor. Then unscrew the self-tapping screw and nuts securing the heater so that you can move it forward (see “Removing the heater heater”).
Disconnect the fan ventilation hose from the nozzle.
Unscrew the 3 self-tapping screws securing the heater fan using a Phillips screwdriver.
Remove the Priora heater fan together with the impeller from the heater housing by prying it off the flange with a flat-head screwdriver.

The fan flange is attached to the heater through rubber pads. To replace them, remove the plastic bushings and then remove the cushions from the holes in the fan flange.

How to remove the Priora stove fan

If the Priora stove is noisy not due to debris in the impeller area, you will have to dismantle the latter in order to repair or replace it. Usually the cause of noise is a bearing failure, but sometimes collapsed impeller blades can make noise.

To dismantle the impeller you will need a Phillips and flathead screwdriver and a knife.

The procedure is as follows:

remove the throttle assembly, but do not disconnect it, but move it to the side;
remove the sound insulation of the engine shield and frill;
bend up the end of the brake pedal mounting bracket;
remove the clamp securing the fan wire block (the easiest way is to cut it);
release the pad lock and disconnect it from the fan;
disconnect the wires from the heater resistor;
Unscrew the self-tapping screw securing the stove mount;
disconnect the fan hose;
unscrew the 3 screws holding the stove;
remove the stove fan by prying it off the flange with a flat screwdriver.

All that remains is to check the operation of the fan and, if necessary, repair it or replace it with a new one.

Fan repair consists of eliminating play in its axis. To do this, you need to disassemble the fan and install an additional washer from below. During subsequent assembly, the rubbing parts should be lubricated with “Litol”.

If the stove makes noise when the engine is not warmed up, and after warming up the noise disappears, it is necessary to lubricate the motor rotor bushing. In this case, you can not dismantle the fan, but remove the frill, drill a thin hole in the area of the sliding bearing and inject oil into it. Then the hole must be closed with a plug.

When installing a fan, it should be positioned so that the pipe to which the ventilation pipe (air duct) is connected is located opposite the latter.

The steps for installing the fan are performed in the reverse order of removal. The clamp holding the wire block should be replaced with a new one.

Installing a Priora interior fan

The catalog number of the electric heater fan of the Priora is 2111-8118020. When installing the fan, turn it so that its branch pipe is opposite the motor ventilation hose. The rest of the assembly is done in reverse order.

By the way, if after replacing the heater fan there is poor air flow into the cabin, then try replacing the cabin filter.

Replacing the stove fan on a Priora

Welcome! Heater fan - thanks to it, air is sent from the environment into the car interior, but it comes from the environment cold, and after it flies into the instrument panel, it passes through the heater radiator (heating radiator, it is correctly called) which can either be very heated , or be too cold (This depends on how the coolant has warmed up, if it has reached its cherished operating temperature of 95 degrees, aiming, then the radiator also heats up very well and all the air passing through it becomes just as warm), that is, simple In other words, a fan is needed for only one purpose: to suck in air from the environment and release it in a certain flow into the car’s interior, where it, after passing through the radiator of the stove, heats up well and comes out warm into the interior.

Note! To replace the stove fan, it will not take very much but also not very little time (Here it still depends on which way you go), strength and tools, the main ones being: All kinds of wrenches, from wrenches to wrenches with socket heads, in addition to this set of various types of screwdrivers you will need and, of course, a new stove fan itself!

Summary:

Where is the heater fan located? It is located under the right side of the windshield if you look in the direction of travel of the car; next to it there is also a cabin filter which is located periodically every 15,000 thousand kilometers, or better even once every 10,000 thousand kilometers, it is recommended to change it to a new one, because when the filter becomes clogged, firstly (If it is a carbon filter) at a certain time, desorption occurs (This is a process in which all the dirt that has accumulated on the filter comes out of it, and when leaving it, it flies straight into the car interior, and the filter collects far from being pleasant things, dust firstly and toxic exhaust gases secondly, we think this will be enough for you to start changing this filter on your car more often and not delay replacing it), but this is not what this article is about We are talking about the location of the heater fan, for clarity, by the way, in the photo below it is indicated with a red arrow, and the blue one shows the same cabin filter that is periodically recommended to be changed on the car.

When should you change your furnace fan? If the fan completely fails, the stove stops working altogether (That is, when you turn the knob of the stove regulator, it will not turn on), if the fan partially fails (And partial failure may include breakage of the blades, the fan motor itself is acting up, etc. .d.) the stove will still work, but during its operation extraneous noises will be heard, such as rustling, humming, whistling, in addition to this, the stove may also work worse and weaker, these will be the most basic symptoms that will appear with partial or complete the stove fan fails.

Adjusting the heater damper

Sometimes the reason that the car interior remains cold is that the heater damper does not open, despite the fact that the gear motor is trying to turn it to the desired position. In most cases, the damper regulator, which is responsible for setting it to the desired position, is to blame.

This is possible on the heater dampers both with and without air conditioning due to a clogged cabin filter, which needs to be changed in a timely manner. Dust and leaves prevent the damper mechanism from opening normally.

Another reason is that the thin plastic of the damper simply warps at high temperatures in the heating line, and it stops reaching the desired position. As a result, the stove does not switch to different modes or the flows are distributed unevenly. Most often, the damper regulator remains in the “in the face” position, but the glass does not blow.

If the damper does not switch, you can remove the panel between the driver and passenger seats; it is located directly behind the central heater grilles. Sometimes you just need to change the seal to which it is pressed, or remove debris that has accumulated in it. After this, you need to check the heater damper in operation and you can assemble the panel.

If there are problems with the damper switching mechanism, you need to remove the plastic on the dashboard near the driver’s right foot. If the plastic damper is deformed, it can be replaced, but it is better to do this under warranty. In this case, repair of the stove damper on Priora is limited to treating the mechanism with VD aerosol lubricant. This can be done blindly, without removing the remaining parts of the dashboard, by feeling the switching mechanism with your hand.

After this, the damper is adjusted by simply switching it to different positions and controlling the movement with your hand under the plastic. In the vast majority of cases, this is enough for the stove to work normally again. After this, install the plastic dashboard in place and secure it with self-tapping screws.

How to replace the heater fan on a VAZ 2170-VAZ 2172?

Note! When replacing the fan, if the cabin filter has not been replaced for a long time, then it can be removed and replaced with a new one, it doesn’t cost a lot of money in car dealerships, but just so you don’t have to get into the car (Still, to change the heater fan, you need to go to that place choose where the filter is installed), you can immediately change it if it is too dirty and thereby drive in the near future with clean air in the car!

Removal: 1) There are two ways by which you can remove the stove fan, we will tell you both, but before we start describing them, let’s talk about them briefly, and which one you will use during the work is up to you to decide, the first method is in removing the throttle assembly, in removing the front panel upholstery and in removing the cooling expansion tank, the second method does not imply this; when choosing the second method, you will only need to unscrew the screws and nuts securing the fan and then remove it from the car.

Note! It would seem that the second method is much more convenient and faster, in fact it is, it is done much faster but is very inconvenient, because in this case you will have to get to hard-to-reach nuts, as well as hard-to-reach screws, etc. etc., while when carrying out the second method, you will no longer need to crawl to hard-to-reach places, all the nuts and screws will be before your eyes, but you will still spend more time, because you will remove other parts that are in the first way and you won’t need to touch it!

2) After you have decided and made your choice, go to work; at the beginning of the operation, in any case, you will need to remove the windshield lining (How to remove the lining, read the article: “Replacing the cabin filter on a Lada Priore”), then the block Disconnect the wires and the connector from each other (They are indicated by a red arrow) and remove the wire block from the additional resistor (It is connected to it, this block is indicated in both photographs by a blue arrow), these are all general operations and will need to be carried out in any case.

3) Read this point only if you are carrying out the second method, but if you don’t want to remove anything unnecessary and if you are not going to do the work using the second method, then in this case go straight to point 4, so about the second method, if it First, you will need to remove the throttle assembly (How to do this, read the article: “Replacing the throttle assembly on a car”), but only when you remove it, do not disconnect any hoses, but simply unscrew the nuts that secure the assembly to the receiver and then remove it, and as soon as the assembly is removed, proceed to removing the dashboard upholstery, to do this, use a screwdriver to loosen the screw that secures the steam removal hose to the cooling expansion tank (This is the tank into which coolant needs to be poured, you will immediately find it), loosening the screw, disconnect the hose from the tank and lead it through the hole in the upholstery (see photo 1), then lift the expansion tank and without disconnecting any other hoses from it, carefully move it, otherwise it will interfere with removing the upholstery, then again, use a screwdriver to unscrew it but this once the lower screw, which secures the upholstery (see. photo 2) and the left part of the upholstery (look as the car is moving) remove from the car, then find three clamps that are attached to the clamps and secure the vacuum brake booster hose so that it does not dangle, and so, overcoming the force of the clamps, remove them from the brackets ( see photo 3), immediately after which, using a socket wrench or wrench, unscrew the nut that secures the steering rack screen in the upper part (see photo 4), as soon as the nut is unscrewed, pull this metal screen and remove it from the top the studs and finally the right (last part) of the upholstery (see photo 5) from the car and bend up the end of the brake pedal bracket (see photo 6).

Repair, diagnostics and replacement of the heater damper on Lada Priora

A comfortable temperature in the interior of the Lada Priora at low temperatures is maintained using a stove. If it breaks down, noise appears in the heater operation, and the ability to adjust the temperature, direction and intensity of the air flow is lost. In most cases, the sources of problems are the motor or damper of the Lada Priora stove, which fail.

Main aspects of repair

If the fan does not work or the stove generally stops working, then you need to understand that the repair process is a rather labor-intensive procedure. Before you remove the heater radiator on a Priora or how to remove the fan, you need to do diagnostics. First, the functionality of the thermostat is checked. If the lines connected to the device are warm, then the part is working.

If the fan does not work, first of all you need to check its contacts. Replacing the stove fan does not always solve the problem, especially if it involves oxidation of the contacts. Sometimes simply cleaning the connector from the device is enough to solve the problem. You can always remove the heater fan, but the heater fan does not fail very often. If the stove blows only at maximum speed, the stove rotation speed resistor has burned out.

In addition, fuse F9 is responsible for the operation of the electrical components of the heating system, so if problems occur, it should also be checked and replaced if necessary. If the fuse often fails, there is no need to buy a more powerful part - first of all, you need to check the electrical circuit using a multimeter. The on-board network may be overloaded due to a short circuit (video author - Alexey Kalachev).

Some car owners on the Internet claim that poor performance of the heating system is due to the volume of coolant in the tank. Allegedly, by removing consumables from the expansion tank to a minimum, the device will release heat more quickly. We would not recommend doing this as it does not solve the problem. But if you leave the antifreeze level in the tank at a minimum, you need to check it regularly.

Sometimes the stove does not heat due to a breakdown of the valve designed to regulate cold and warm air flows. If the air flow is very weak, you need to check. What is the condition of the filter being used? The air filter element needs to be changed from time to time, remember this. When the heater is very noisy, the problem is usually a bad bearing. In any case, the bearing device needs to be replaced, since over time it can simply jam the fan, and this, you see, is much more serious than just noise in the cabin.

Sorry, there are no surveys available at this time.

Heater device on Priora

The liquid-type heating system on the Lada Priora is structurally connected to the engine cooling system and includes:

radiator or heat exchanger of the heating system;
a fan supplying air to the cabin;
damper that regulates air temperature;
heater damper reducer;
damper for flow distribution on deflectors;
deflectors.

A failed heater damper on a Priora does not close completely, so the warm flow mixes with cold air without warming up to the required temperature and the cabin is always cool and uncomfortable. To fix the problem, you need to remove, replace or repair the heater damper gear motor.

Replacing the gearmotor

If the damper does not work, hot or cold air blows from the heater, and the ability to adjust it is lost. In such a situation, the cabin heater gearmotor must be replaced.

Replacing the damper on a Priora begins with raising the hood and removing the wipers. To do this, remove the plastic caps and unscrew the nuts with a 14 wrench, after which they are easily removed. Next, the left and right frills are dismantled by removing the rubber pad, protective plastic caps and unscrewing six screws. Then the plastic soundproofing of the engine compartment is removed, the cooling system hose passing through it is carefully disconnected from the expansion tank, then the tank itself is removed. To avoid draining the coolant, the holes in it must be plugged.

To inspect the heater gear motor, remove the expansion tank mounting bracket by unscrewing two bolts under the wing and removing the protection above the left front wheel. After this, the wiper motor and trapezoid are dismantled.

Now the unit is being dismantled; first you need to carefully disconnect the heater damper sensor and the power supply contacts. After this, install and check the new spare part, reassemble everything in the reverse order, and the replacement of the stove gear motor is completed.

Replacing the heating gear motor on a Lada Priora

First of all, it should be said that replacing the gearmotor on a Priora with and without air conditioning is done in the same way, since the gearbox is located quite far from this device. It should also be noted that today there are several known ways to remove the gearmotor from a Priora. One of them involves removing only the trapezoid along with the wipers and expansion tank, the second allows you to get by with removing only the tank. But to use these methods, the driver must have extensive experience in self-repair, otherwise problems are inevitable. Therefore, the third method will be discussed below, with the complete removal of all necessary parts. Yes, it will take more time from the car owner, but it is almost impossible to break anything. Now it's time to decide on the tools. Here's what we need:

new gear motor for Priora;
2 screwdrivers - flat and Phillips.

Sequence of work

First you will need to perform a few simple preparatory steps. It is necessary to disconnect the throttle valve assembly and move it slightly to the side.

To get to the Priora gearbox, the sound insulation will have to be removed

Then use a Phillips screwdriver to unscrew the screws holding the sound-insulating material.

There is a wiring harness next to the gearmotor. It is mounted on plastic holders that open manually. The tourniquet is pulled aside.

The wiring harness is mounted on two plastic holders that can be opened manually

The heater is held on by three screws. It only needs to be moved a few centimeters

You need very long fingers to reach the block on the damper sensor.

Gearmotor repair

In most cases, the extraneous sounds produced by the heater damper drive on a Priora are associated with cracking of the plastic gear. When its teeth are cut off, the mechanism stops working normally. Replacing it is quite difficult, but possible. After dismantling the gearbox, release the compressed plastic cover and bend it, then carefully remove it.

After carefully inspecting the mechanism, determine which gears are faulty and install new ones. Determine the condition of the commutator, bearings and brushes of the mechanism. Lubricate the bearings with silicone grease, which does not harm other structural elements. If after assembly the system functions normally, replacing the heater gear motor will not be necessary.

Replacing a radiator heater on a Lada Priora (with or without air conditioning)

One of the reasons for poor heater performance is the furnace radiator . While the vehicle is in use, it begins to leak and can no longer provide the required amount of heat to the cabin. Depending on the year of manufacture and the complete set of Lada Priora, the process of removing the oven (radiator) can be very different.

How to remove a stove radiator on Priorat without air conditioning

Since the start of production, AvtoVAZ has installed a heater from the Top 10 on the Priora (catalog number: 21110-8101012). The disadvantage of this design was that the heater radiator was removed in the direction of the vacuum brake booster, which allows. As a result, the heater assembly must be removed.

The procedure looks like this:

Remove the windshield wiper blades.
Remove the protection (windshield).
Remove the sound insulation from the engine shield.
Disconnect the stack of connectors with wires.
Unscrew the heater mount.
Divide the heater into two parts (left and right).
Remove the right side of the heater (in the direction of travel).
Move the left side out of the way to gain access to the furnace radiator.
Drain the antifreeze.
replace the furnace radiator .

The whole procedure took several hours. This is shown in more detail in the video:

There is another way to replace it. To gain access to the furnace radiator, it is necessary to remove the vacuum brake booster along with the brake pedal instead of the heater housing. This allows access to the left side of the heater (in the direction of travel) and to the radiator itself.

Replacing the heater radiator with Prior for air conditioning

After some time, the manufacturer began to equip its cars with air conditioners (for example, HALLA or Panasonic (Ref: 21703-8101012). The design of the new Priora heater has become much more convenient in terms of maintenance. Now you do not need to remove the can, wiper blades, heater or vacuum brake booster for replacing the hob.

All you need to do is remove the engine shield noise shield, remove the air filter hose, the engine seal and the heater radiator . All! We drain the antifreeze and remove the radiator towards ourselves, towards the engine.

Video instructions are attached:

So, replacing the stove radiator. Priorities depend not only on the type of insulation, but also on the chosen method of replacing it. And how did you shoot the heater radiator in your car? Which method suits you best? Let us remind you that solutions to other problems with plates can be found in this article.

Important points

There are a couple of nuances, without mentioning which this article would be incomplete:

So, replacing a heating gear motor is not a very difficult task and even a novice driver can do it. If a person has held a screwdriver in his hands at least once, he can handle it. All you need to do is follow the above recommendations exactly.

Lada Priora Hatchback KosmosS › Logbook › Replacing the heater motor with Panasonic air conditioner

I drove for the last month and suffered with my air conditioning.

The symptoms were bleak; the air conditioner either worked or didn’t.

In other words, the air conditioner worked properly, but the heater motor

He was obviously shirking his own work.

Especially when you drive on smooth Russian roads))

Symptoms: the motor refuses to operate in all positions of the rotation speed control handle.

At first there were floating speeds, later it completely died out, and from time to time it came to life on bumps.

I thought there was a bad contact in the connector. I got to the connector, everything is ok.

If you lightly hit the fan body, it comes to life and continues to work normally, which means the reason is in the motor itself, and not in the control unit or connector contacts

I was completely fed up with this and now I dared to change it...

It turns out this is very difficult to do and spare parts

you need the original. Panasonic ept)))

To be honest, it got me, it’s either the original regulator or the motor (((

Replacing a Priora stove motor with Panasonic air conditioning

Maybe this is the replacement

and not faithful, but frisky!

According to the repair manual, I had a very difficult job ahead of me.

with the removal of the vacuum and the halving of the entire stove together with the evaporator and subsequent

refilling with freon. In short, only with freon for 2 rubles is not enough work for 5-6 hours.

But I did it even simpler))

Naturally, my hand didn’t rise to shred and cut my car, but what can you do.

There is no way without this. Priora ept)) Thanks to AvtoVAZ for their foresight in the next repair. All that was necessary was to make the upper part of the heater in the area of the motor removable. But no, we are not looking for easy ways; the right way is to remove everything))

Therefore, I did it much simpler and first cut off the upper part of the heater motor casing with a hacksaw blade. So that nothing would interfere with its removal. Cut only as shown in my photo so as not to disturb the rigidity of the entire casing. And it is this half that I cut off that only plays the role of an anther.

But this turned out to be not enough... The motor rested against the place where the engine mount was mounted on the glass. This was done specifically so that no one could remove the motor in this way without completely disassembling the heater. But we move on))

In general, we cut the fan casing itself, but so that the 2 motor fasteners are outside the cut (this will not affect its rigidity). You can see in the photo where to cut.

Well, now that the engine is in front of us, we see its Chinese origin and the savory price for it. But in terms of mounting, it is completely identical to the 10 Mu and Kalinovsky. It only differs in the location of the breather, but this is not a hindrance for us.

We put the motor in place and check everything works. This means we can assemble it.

I then coated the incision sites with Poxypol and everything was fine. The integrity was not compromised and the appearance was not damaged at all; it is not visible there.

But it made it easier for me to disassemble and maintain this unit in the future.
