With the onset of cold weather, every motorist tries to create comfortable and warm conditions for staying in the cabin of his car, because no one wants to freeze. But if warm air does not enter, it should be determined what this may be due to. In this article we will consider the repair of the Lada Kalina stove control.
The principle of operation of the stove is supply and exhaust. The air masses in the car are heated with the help of a special fluid that simultaneously cools the engine.
The principle of operation of the heater is that the liquid heats the radiator, in which heat exchange takes place, and the heated air enters the passenger compartment through air ducts.

Where is the stove on Kalina
On Kalina, the stove switches are located on the central instrument panel. The heater control unit is located in the instrument panel console.
How Kalina stove control works
The oven control mechanisms are as follows:
- Air flow distributor control regulator.
- Regulator of fan operation modes.
- Furnace temperature controller.
- Lever for switching the recirculation damper.
The temperature controller switches from cold to hot and vice versa. The air supply is controlled by a switch that has four modes of operation of the electric fan. The fan speed is increased by turning the knob to the right.
Tools, consumables, fixtures
To remove the control box, you will need Phillips and slotted screwdrivers.

How to find a fault
If cold air blows from the stove and no heat comes in, consider the main causes of such malfunctions:
How to repair Kalina stove control
Impossible or difficult switching of the temperature mode controller may be due to a breakdown of the switch itself. Replacing the stove switch on Kalina is quite easy (provided that the dismantling of the stove control mechanism has already been completed). On the rear console of the control panel, unscrew the four fixing screws of the switch box. Remove the cable fasteners and disengage the cables from the drive unit. Replace broken switch. Assembly is carried out in the reverse order. When performing these works, mark the location of the cables on the lever block with a marker. This is necessary in order to install the rods correctly during assembly.
The main reasons for the breakdown of the stove temperature controller can be: a breakdown of the thermistor or a broken connection wire. Such malfunctions are eliminated by replacing the broken element and by soldering the wire. Also, the stove regulator may stop working due to the failure of the temperature sensor, which is quite rare. This sensor is located inside the ceiling in the passenger compartment of the car.
How to change the heater control unit
Work order:
- Remove the cover from the console.
- We unscrew the four screws securing the control unit to the instrument panel frame.
- We dismantle the cable clamps that are involved in controlling the heater.
- We remove the cables with drive mechanisms. We sketch the position of the cables on the elements of the block in order to install everything in its original place during assembly. The most difficult thing is to put on the cables and fasten them with a latch.
- We remove the control unit for the stove with air conditioning.
- We put a new block on the car.
- We assemble the elements of the assembly in the reverse order and put the overlay of the instrument panel console.
Now it remains only to check the stove for performance. We start the car, check the operation of the dampers in various positions and modes of operation of the stove fan. Next, we warm up the engine to operating temperature and make sure that the stove heats up normally.
Lada-Kalina is equipped with either a heating and ventilation unit (top picture) or climate control (bottom picture).
The heating and ventilation unit is used to create a comfortable air temperature in the passenger compartment, the value of which is regulated by the control unit for the ventilation and heating system, but at the same time it cannot provide a temperature in the passenger compartment lower than the outside air temperature.
There is an air filter in the air intake box, which cleans the air entering the car interior from dust, pollen, soot, and small insects. The filter must be replaced every 15,000 km (or sooner if the operating conditions are severe).
- switch 1- controls the fan operation mode (0 - fan off, 4 - maximum rotation speed);
- switch 2- controls the operating mode of the stove and air conditioner (in the variant version);
- handle 3- controls the air recirculation damper (leftmost position - supply of outside air to the passenger compartment, extreme right position - recirculation mode of air in the passenger compartment - this mode is not recommended to be used for a long time);
- switch 4- controls the distribution of air supply in the passenger compartment:
- vertical position up- air enters the windshield and the nozzles for blowing the windows of the front doors;
- vertical down- air enters the lower part of the passenger compartment, into the zones of the legs of the driver and passengers;
- horizontal position right- air enters through the side and central nozzles into the upper part of the car interior to blow the driver and passengers;
- horizontal position left- air enters the lower part of the cabin, into the areas of the driver's and passengers' feet, onto the windshield and the nozzles for blowing the windows of the front doors.
The levers 9 and 5 of the damper drive regulate the intensity of the air supply through the side (8) and central (4) nozzles by changing the position of the dampers (up to their complete closure). The levers 1 and 3 of the guide vanes of the side and center nozzles change the direction of the air flow.
Ventilation (unheated air supply) of the passenger compartment:
- set switch 2 to the extreme left position (blue dot on the control unit) - the tap of the heating stove is completely closed;
- set switch 4 to the horizontal right position;
- open nozzles 4 and 8, turn lever 5 on the central nozzle down, and lever 9 to the right on the left side nozzle and to the left on the right side nozzle;
- switch 1 of the heater fan operation mode set to the desired mode;
- in case of fogging of the windshield, set the switch 4 to the vertical position upwards.
Preventing glasses from fogging up:
- set switch 4 to the vertical position upwards;
- Set switch 1 for operating modes of the heater fan to position "2".
Quick interior warm-up:
- set switch 2 to the extreme right position (red dot) - the tap of the heating stove is fully open;
- set switch 4 to the horizontal position to the right;
- set switch 1 for operating modes of the heater fan to position "3";
- open the side and center nozzles.
Ensuring a comfortable temperature in the cabin:
- set switch 2 to the desired position (desired temperature);
- set switch 4 to a horizontal position to the left;
- using switch 1 of the operation mode of the interior heater fan, select the required intensity of warm air supply to the passenger compartment.
When the heating system is operating in the maximum mode, it is not recommended to open the windows of the car interior.
The ventilation and heating system of the car interior is a forced-air and exhaust system, while the temperature of the liquid heated above 90 ° C from the engine cooling system is used for interior heating.
When the doors are closed, air is supplied to the passenger compartment by an electric fan. The air supply intensity is controlled by the rotation speed of the electric fan impeller. The fan motor has four speed settings (reduced speeds are provided by an additional resistor with two windings). Air intake is carried out through an air intake installed under the windshield frame. To clean the air entering the passenger compartment, a filter element made of non-woven synthetic material is installed on the air intake of the heater.
Basic data for control, adjustment and maintenance
The hood is carried out due to the rarefaction that occurs near the rear of the body when the car is moving. Exhaust vents are built into the body panels under the rear bumper.
Heater details: 1 - filter housing for the ventilation and heating system; 2 - filter element; 3, 4, 5, 6, 7 - air ducts; 8 - casing of the radiator and heater air distributor; 9 - heater radiator; 10 - casing of the electric fan of the heater; 11 - heater electric fan
The interior is heated by a heater installed under the instrument panel. When the engine is running, heated fluid from the cooling system circulates through the heater core. heating the air passing through it. The amount of air passing through the radiator and bypassing it is set by the central heater damper, depending on the position of the temperature control knob installed on the instrument panel. The distribution of air in the passenger compartment can be adjusted by turning the air distribution dampers control knob, as well as by turning the dampers and guide vanes of the instrument panel ventilation grilles.
CHECKING THE TECHNICAL CONDITION OF THE VENTILATION AND HEATING SYSTEM
1. We prepare the car for work.
2. We start the engine.
3. We turn the knob of the air temperature regulator counterclockwise to the extreme position (blue sector).
4. Using the heater fan control knob, turn on the four speeds of the electric fan in turn. By the intensity of the air flow from the nozzles, we check the operation of the electric fan and the change in the speed of rotation of its impeller when changing modes (1 is the minimum speed, and 4 is the maximum). If the electric fan does not work in all modes, we check the additional resistor and switch. If the electric fan does not work, then check the power supply circuit of the electric fan.
5. Turn on the maximum speed of the electric fan.
6. By turning the control knobs for the heater dampers and ventilation grilles, we monitor the change in the direction of air flows. If there is no change in flow distribution, the damper actuator is most likely defective.
7. After warming up the engine to operating temperature, turn the knob of the air temperature regulator clockwise to the extreme position (red sector).
8. We make sure that the air coming out of the panel nozzles has become warm. If the air temperature has not changed, the central damper actuator may be faulty.
9. We turn the temperature control knob to the blue sector - cold air should go into the cabin. If the temperature does not drop, then the central damper actuator is faulty.
Probably every motorist eventually encounters. The owners of Lada Kalina are also, unfortunately, no exception. Sometimes it is very difficult to understand the true cause of poor interior heating, when a normally working heater suddenly begins to fail to cope with its task.
The problem of weak heating can be solved by replacing and adjusting the stove damper on the Lada Kalina.
Car heater Lada Kalina
What is the shutter responsible for?
During the operation of the motor in the cooling system, the heated liquid moves through, while it heats the air passing through it. The volume of air passing through the radiator and outside it is controlled by the main damper of the stove. Depending on how the temperature control knob is located on the dashboard, the amount of incoming air will depend.
You can distribute the movement of air throughout the cabin by turning the handle that regulates the position of the damper. But there are cases when the damper is stuck and it is impossible to properly regulate the flow of heat into the interior of Kalina.
If the matter is only in the valve, then the situation can be corrected quite simply by pulling up its cable. If after these actions the situation has not changed for the better, then you need to conduct a visual diagnosis of the state of the mechanism and perform a number of simple actions.
How can I check the operation of the heater damper?
- Set the temperature control knob on Kalina to the extreme position of the blue sector, and the fan speed to the maximum value.
- Turn the damper control knob on the unit and simultaneously observe the change in airflow direction.
If the air flows remain unchanged, then this indicates a breakdown of the mechanical control unit of the stove. Most likely, the thrust fell off, it stopped wrapping on the roller due to its malfunction. Or the second option could be that . If your car has climate control, then check the damper micromotor and check the condition of the ventilation, stove and air conditioning control unit.
How to get to the damper?
To see where the central heater flap is located, you will need to partially disassemble the dashboard, specifically, unscrew the beard. This is the place on where the heater switches are located.
Progress:
- Remove the ashtray.
- Squeeze out 2 plugs located next to the emergency button.
- Remove all control knobs.
- Unscrew the 2 screws of the center console and carefully pull it out, while prying it in place of the latches.
- Disconnect all wires.
- Now you can freely reach the damper.
- Replace the damper or its drive components.
Very often, the cause of a malfunction can be a broken damper drive mount. If the situation is not critical, then you can simply glue the part that has fallen off with superglue.
There are times when the valve actuator mount breaks off due to an undeveloped cable that falls very tight. In this case, it must be developed manually, after which this problem should not arise.
How to adjust the heater damper on the Lada Kalina?
- The first step is to adjust the heater valve.
- Remove the bracket that holds the cable sheath to the faucet body.
- Remove cable from faucet lever.
- Open the faucet to the maximum.
- Unhook the cable from the lever block.
- Remove the old cable.
- The tap may not be closed at all in the future.
If you do not like the method described above, then you can use another one:
- Adjust the length of the sheath and cable so that in the extreme right position of the lever on the block, the valve opens completely.
- Fix the cable, located in this state, with a latch.
- Then proceed directly to the adjustment of the heater damper.
- Remove the bracket that holds the cable sheath on the heater body and feel for the galvanized yellow lever located on the left.
- Pull the lever towards you - this will be the maximum open state.
- Adjust the length of the cable so that in the right position of the long lever on the lever block, the valve is opened to the maximum.
- Fix.
- Do not forget that with the help of one lever both dampers are simultaneously controlled: both the crane and the large one.
Definitely, the heater in Lada Kalina heats much better than in.
But the incorrect operation of the heater dampers, unfortunately, is a very common "disease" of Lada Kalina. Therefore, after the purchase, try to prepare in advance for the heating season, especially since you can do it yourself quickly and easily.
In addition, quite often problems with the stove can appear due to the car's engine cooling system. We advise you to check the level of antifreeze in the expansion tank. If it is insufficient, it is necessary to add coolant to the normal level mark.
It is worth noting that many drivers in winter deliberately leave antifreeze at the minimum mark, due to which in cold weather the heating system starts to blow warm air faster.
Method for checking the stove on Lada Kalina
The whole procedure is carried out on a running engine.
Checking the heating and ventilation system fan:
- We move the temperature control knob of the control unit to the extreme position (blue zone).
- Smoothly switch the fan speed from the first to the fourth speed.
- We monitor the intensity of incoming air, outgoing and air duct. With each speed, its flow must increase.
If the air flow does not change its direction, this indicates a malfunction in the mechanical part of the heater control unit. For example, the thrust has flown off or, due to a breakdown of the roller, it does not wind onto it, or the damper has simply jammed. At 
installed climate control, it is worth checking the operability of the micromotor reducer of the damper of the ventilation unit, air conditioning and heater. For this:
- warm up the engine to operating temperature;
- the temperature controller is transferred to the extreme red zone;
- we control the presence of warm or hot air flow from the air ducts.
If the temperature of the air flow has remained unchanged, the operability of the mechanical part of the heater control should be checked. When using climate control, we carry out the above operations. We also check the health of the engine cooling system.
