Car owner's opinion: External and internal design, comfort, handling.

If your car's heater fails on the road, it doesn't bode well. Neither the car nor the driver. Especially if it’s far from home, and it’s thirty degrees below zero outside. Any driver can find himself in such a situation, including the owner of a Lada Priora. The heating system in this car is implemented quite successfully, but it has one extremely weak point: the gearmotor. The reliability of this device leaves much to be desired, and it can become a source of headaches for the driver. However, a broken gear motor can be replaced with your own hands. Let's figure out how this is done.

Purpose of the heating gear motor on the Lada Priora

A gearmotor is a device consisting of several plastic gears driven by a small electric motor. The main task of the gearmotor is to open and close the heater damper depending on the position of the regulator on the dashboard.

Geared motors on Priora are made only in plastic, non-separable housings

The plastic from which the gears are made deteriorates quite quickly. After which the driver is forced to change the gearbox. This device cannot be repaired, because, firstly, it is not possible to find spare parts for it, and secondly, it is not so easy to open the plastic housing of the gearbox without breaking it. So there is only one option left: replacement.

Gearmotor location

The gearmotor on the Lada Priora is located near the expansion tank, under the windshield.

The gearmotor on the Priora is located under the windshield near the expansion tank

It is built into a niche on the wall of the engine compartment and covered with a thick layer of sound-insulating material. This material will have to be removed, since otherwise it will not be possible to get to the gearmotor.

Priora interior heating system

The vehicle is equipped with a stove (heating system) with a climate control system that provides comfort while traveling in the car. They are designed to eliminate problems in the event of cold weather or other weather changes. No one will ask the question why the stove in the Priora does not work, neither the driver nor the passengers.

The car's climate control system includes:

the stove itself (heater);
stove fan device;
temperature sensor in the cabin;
air distributor housing;
airways;
deflectors (directing the flow of air masses).

The air flow from the stove is transmitted to the housing part of the air distributor, from where it is directed along air lines. Through the air ducts, the flow flows to the windshield grilles of the windshield and side windows, to the air mass flow guides in the center and side of the dashboard, as well as to the lower plane of the cabin to the floor pans on the bottom of the body. With the advent of frost, defects in the heating system appear, the most unpleasant of which is that the Lada Priora stove does not work and other malfunctions.

Signs and causes of gear motor failure

There are two signs of a gearmotor failure on a Priora. Here they are:

when starting the heater, a loud grinding or knocking noise is heard from under the dashboard, which becomes louder as the heating fan speed increases;
inability to adjust the oven temperature. The heater blows either only hot air or only cold air. The position of the temperature regulator on the dashboard does not matter in this case.

All of the above happens for very specific reasons. Here are the most common of them:

one or more teeth on one of the gear motor gears has broken. The tooth fragments rotate together with the damaged gear and hit the plastic housing of the gearbox from the inside. As a result, a characteristic dull rattle or knock occurs, which is clearly audible in the cabin;

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.

To open the spring lock, you will have to move it down a couple of centimeters

The gearmotor is held on by only three self-tapping screws, unscrewed with a Phillips screwdriver

Repair and replacement of heating faucet

If, in fact, it turns out that the stove on the Priora has stopped functioning as it should due to an inoperative faucet, the car owner will have to replace the failed structural element. To do this, consider a detailed and very accessible step-by-step plan for replacing the above part.

As for the necessary tools, the motorist will only need a 10mm socket and a wrench. After everything is ready, you should begin to implement the idea, initially ridding the cooling system of the power unit of the antifreeze contained in it.

Then it is necessary to dismantle the glove boxes on the Priora, in addition to removing the luggage rack. Only after carrying out all the steps described above, even an amateur motorist will be able to independently replace the heater tap.

The next step is to loosen the clamps that secure the heating system hoses. It should be noted that all these parts are located directly in the engine compartment. The motorist will have to disconnect the hoses and pipes of the heater tap. Before starting this process, it is important to mark the location of the pipes to be removed. In exactly the same way, you should disconnect the hoses that come from the heater tap in the car interior.

Having completed these steps, the novice mechanic will see the area where the Priora stove faucet is located and will be able to independently unscrew both nuts responsible for fastening the structural element being replaced. Then you can begin to remove the heater tap, while working on the cable tension. It is imperative to remove the bracket and remove the cable that is connected to the crane lever. Only these actions will help you remove and change the tap of the heating device. At this stage, we can consider that half of the actions are over. All that remains is to get rid of the rubber seals and install the new stove faucet back in the reverse order of its removal.

Important points

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

The old gearbox should be removed very carefully. A long shank sticks out of it. If you remove the gearbox at an angle, you can damage the edge of the hole for the shank. If this happens, installing a new gearbox will not be so easy. Therefore, advice: when removing the gearbox, it should be pulled in a plane parallel to the floor;
When buying a new gearbox at a car dealership, you should only buy the original VAZ one. Yes, its quality leaves much to be desired. But this is still better than buying a fake gearmotor, which the spare parts market is literally flooded with now. You can spot a fake by price. A normal gearmotor on a Priora costs 700 rubles and more. And a fake rarely costs more than 300 rubles.

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.

Climate control Lada Kalina Lux

The system design is similar to that described above, with the exception of some details. To maintain a given temperature in the cabin, two new elements are used in the design: a temperature sensor in the cabin (built into the ceiling light) and a damper micromotor reducer. Also, the mechanical control unit has been replaced with an electronic one, with degrees of air temperature in the cabin marked on it.

The operation scheme is as follows: the control unit periodically receives a signal from the temperature sensor in the cabin and compares it with the temperature set on the unit. If the difference is too large, the control unit sends a signal to the micromotor gearbox, which already controls the heater dampers (opens or closes hot air from the heater).

Preparatory stage

Troubleshooting the heater should begin provided that the power unit and engine cooling system are in order to eliminate their influence. To do this, you need to make sure that the antifreeze is poured in the proper amount, the engine is in good condition and is functioning normally. And after that, find out why the stove on the Priora does not work. First, check the coolant level in the expansion tank. Next, you need to start the engine and warm it up to operating temperature. After this, you need to check the serviceability of the thermostat - feel the thick hoses that go from it to the car radiator.

The top one should gradually become hot. If the rubber hose is still cold, the thermostat is faulty. In this case, you can continue working only after replacing this element. Fortunately, its cost is low.

Another reason why the engine may not warm up to operating temperature is a leaky expansion tank cap. It should keep excess pressure in the system. Often, simply replacing this cover can completely eliminate the problem.

On the Priora, unlike the Tens, the cooling system is organized differently. And the formation of an air lock there is practically excluded. It can occur when the system is leaking or when antifreeze is poured into a completely empty expansion tank. This can be fixed quite simply. You need to drive your front wheels up some hill in a warm car and vigorously apply the gas in place. The expansion tank cap should be removed.
