Instructions for controlling a heater with air conditioning and the principle of its operation in Kalina

The interior heater is one of the most important elements of the entire car, because its efficiency increases comfort and even in some cases can save a person’s life. Lada Kalina has been produced for quite a long time and during its entire existence it has undergone many changes that affected not only the appearance, but also the car’s heater. Depending on the version of the car, the heater on Kalina may differ, for example, in the luxury version of the car, some kind of climate control is installed, but in the simple version, the interior heater does not have an air conditioning system.

One of the important parameters for the efficient operation of the stove is a working engine cooling system, which significantly affects the operation of the entire heater as a whole.

Elements of the heating system LADA Kalina

The ventilation and heating system of the car interior is a supply and exhaust system, while the temperature of the liquid heated above 90 °C from the engine cooling system is used to heat the interior.

Heater parts: 1 — filter housing for the interior ventilation and heating system; 2 - filter element; 3, 4, 5, 6, 7 — air ducts; 8 — radiator casing and heater air distributor; 9 — heater radiator; 10 — casing of the electric heater fan; 11 — electric heater fan

Ventilation and heating system element:

• electric motor assembled with impeller 1118-8118020-01
• electric fan switch 1118-3709608
• additional heater resistor 2123-8118022

Diagnosis and troubleshooting

The easiest way to resolve the issue is regarding the cabin filter. For the first time, thorough blowing of the element will be enough, but then it is better to replace it. The real problem is a leaking radiator or a broken fan; an expensive replacement of the unit cannot be avoided. An equally high price will have to be paid for a new control unit.

It will be somewhat cheaper to install a new temperature sensor, gearmotor or resistor for the Kalina heater. Moreover, the malfunction still needs to be correctly diagnosed, which can be quite difficult. A burnt resistor is easily identified - the fan only runs at maximum speed.

It is more difficult to check the sensor hidden in the lighting shade. Symptom of a malfunction - a hot or cold stream flows from one or more grilles, regardless of the position of the regulator handle.

It is more difficult to detect how well the mechanical heater regulator is functioning. To do this, you need to get to it by disassembling part of the front panel. In the same way, the proper operation of the air dampers is determined.

The air distribution throughout the cabin can be adjusted by rotating the control knob for the air distribution flaps, as well as by turning the flaps and guide blades of the instrument panel ventilation grilles.

List of faults in the heating circuit

If the owner of LADA Kalina suspects the presence of any deviations from the normal functioning of the heating system, then the diagnostic procedures below will be required.

1. The first step is to make sure that there is a sufficient amount of antifreeze in the cooling circuit.
2. Next, check the integrity of the fuse.
3. We make sure that the fan speed regulator is working properly.
4. A weak air flow through the deflectors indicates the need to check the condition of the filter component.
5. If there is no warm flow into the cabin when the engine is warm, then there may be air pockets in the cooling system or the dampers in the air ducts are jammed.
6. A faulty temperature sensor will cause only hot or, conversely, cold flow to enter the cabin.
7. Among the common reasons is depressurization of the LADA Kalina cooling system. Sometimes this may be due to the loss of tightness of the heater radiator itself. At the same time, antifreeze will enter the cabin, giving itself away as a specific smell and wet decorative floor covering. In order to detect a leak in a timely manner, it is necessary to monitor the level in the expansion tank frequently.

Interior ventilation of LADA Kalina

Exhaust deflectors are built into the body panels under the rear bumper. The interior is heated by a heater installed under the instrument panel.

1 - air supply ducts for passengers in the rear seat. 2 - side nozzles for supplying air to the driver and passenger on the front door or on the windows of the front doors. The air flow is controlled by grilles (in the vertical direction and flaps in the horizontal direction. 3 - glass blowing nozzles. 4 - windshield blowing nozzles. 5 - upper air supply nozzle. 6 - central supply nozzles to the cabin.

Control unit for ventilation and heating system LADA Kalina

1 — air temperature regulator;
2 — fan operating mode switch; 3 — air flow distribution regulator; 4- air recirculation control lever; 5 — rear window heating switch The intensity of the air supply into the cabin is regulated by turning the handle of the fan operating mode switch. This turns on one of four fan speeds. By turning the switch handle clockwise, we increase the fan rotation speed.

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;
• The gear motor burned out. This usually happens due to sudden voltage surges in the on-board network. For example, when the battery in a car died and the driver tried to “light up” from another car, but at the same time mixed up the contacts;
• There were problems with the power supply to the motor. The gearbox itself and its motor may be in good working order, but electricity is simply not supplied to the gearmotor. This can happen for a variety of reasons, but the most common is a blown fuse that supplies power to the gearmotor.

How the Lada Kalina stove works

The vehicle's heating system must work properly. It is not difficult to achieve uninterrupted operation of the stove if you know the structure of the Lada Kalina stove. The heater creates a comfortable stay in the car interior, creating visibility for the driver. The stove design provides for the use of small-class machine options. The production of Kalin cars began over ten years ago. The following options are included for the base model:

• Anti-lock braking system.
• Airbags.
• Electric power steering.

New Lada Kalina models were developed, which were already equipped with additional options:

• Electric door window lifts.
• Reliable heater.
• Heated seats.
• Interior air conditioning device.

Summary

The Lada Kalina car is available with a ventilation and heating unit or with an air conditioning unit. For the first option, it is impossible to provide a cabin climate whose temperature will be lower than the ambient temperature.

The heating system in the cabin of the budget Lada Kalina model can significantly increase comfort for the driver and his passengers. It ensures that the required temperature conditions are maintained inside the car. Along with such useful options as:

• "ABS";
• airbag;
• electric power steering;
• electric front windows;
• front seat heating function,

The design of the interior heater allows the manufacturer to achieve a fairly acceptable level of equipment, which is very worthy for a small-class Lada Kalina model and makes it competitive among its rivals in this segment.

Checking ventilation and stove Lada Kalina

Car owners claim that Kalina’s heater heats much better than previous VAZ models. It sometimes breaks down and requires repair. Do a full system diagnostic to ensure it's working properly.

1. We start the car engine.
2. Turn the left handle counterclockwise and place it in the blue zone.
3. We place the fan speed switch in each of the 4 positions one by one. If the fan does not rotate in one of the positions, then check the power supply circuit of the device.
4. Turn the speed controller to maximum.
5. Using the right handle (damper control) we check the redirection of air flows. If we notice that there is no change, then the damper drive needs to be repaired.
6. Warm up the engine to 90°C. Turn the left handle to the extreme position of the red zone.
7. The air that comes out of the panels should blow warm air.
8. Return the left stick to the blue zone. Cold air will come out of the nozzles again.
9. If the temperature of the air flow does not change due to a change in the position of the regulator, then the control of the central damper drive is faulty.

How to change a radiator

The operation is very labor-intensive, for which the car service center will charge you a hefty sum. But there is another, slightly barbaric, but fast and widely practiced method. The work flow diagram is as follows:

1. Drain the antifreeze, disconnect and remove the battery, and then disconnect the hoses from the heater pipes.
2. Unscrew the nut located near the fittings in the engine compartment. It holds a steel plate that will interfere with the removal of the heater.
3. Remove the gas pedal and pull out the steel brake pedal shaft. Unscrew the decorative panel and behind it the plastic panel covering the stove radiator.
4. To remove it, cut an opening in the plastic frame that allows you to pull the radiator towards the driver.
5. Install the new element and reassemble in the reverse order. The cut opening can be sealed with plastic and decorated in any suitable way.

When performing the operation, it is worth moving the controller located directly under the stove to another place. Antifreeze dripping from it can damage sensitive electronics. Also, with the radiator removed, it is easy to change a faulty heater valve or gear motor, because access to them will be open. The gearbox is a single unit with a damper position sensor and can also be changed entirely.

Possible heater malfunctions

Your stove is not working or is not heating well. Look for the cause of the problem. The fan does not work or the heater radiator is leaking - obvious breakdowns that occur at any time.

Stove control unit:

• The engine was warmed up, but warm air did not enter the cabin.
• The damper drive cables may have come off. The only solution is to remove the console.

Dampers . Partially open or close. The rubber seal has come off in the air duct or foreign objects have gotten into it.

Antifreeze circulation . Start the engine and check the level in the expansion tank, and also check for any disturbances in the normal flow of antifreeze. Possible reasons:

• Pump. Cannot be repaired, only replaced.
• The cooling system is clogged. Clean or rinse.

Checking the thermostat . Warm up the engine to 75°C. If the upper pipe is cold, then the thermostat does not work correctly and does not allow coolant to move in a large circle. Replace the device.

Air lock . Remove the plug from the vehicle's engine cooling system.

Temperature sensor . Constantly blowing cold or hot air. If cleaning the contacts does not help, then replace the non-working temperature sensor.

Air filter . If the air flow is weak and there is no desired temperature, then replace the filter. Be sure to check the heater resistor, which controls the rotation of the fan and is located under the glove compartment.

Electric fan . The device does not turn on regardless of the selected mode. Check the fuse that controls operation. If the fan is turned on and its operation is accompanied by strange sounds, clean or replace it.

Dampers . It is difficult to determine the breakdown unless you replace the dampers themselves.

The cause of a heater malfunction may be a depressurization of the car's engine cooling system. The types of breakdowns described above cause malfunctions in the operation of the Lada Kalina car's stove. Such breakdowns do not require special knowledge; they are easy to understand and repair.

The main reasons why the stove on Kalina does not work

Of course, the stove on Kalina heats just fine, but, like any mechanism, it tends to wear out. And problems begin: the fan doesn’t spin, or it just doesn’t blow well. Or the stove is blowing cold air.

But don’t be upset, because this can all be fixed. Let's look at the main reasons why the stove does not heat well and blows cold air.

Stove fan

If necessary, it must be replaced, and if possible, repaired. But first check the fan fuse in the mounting block, it may have simply blown.

Coolant level

If necessary, add coolant level

Airing the system

Remove the air and be sure to find where this air may be getting into the system.

Heater radiator

Of course, changing a stove radiator is still a pleasure. And the price for repair work is not low. Well, what to do if it’s cold in the cabin and you know for sure that the reason is in the radiator.
