Lada Vesta stove design

The Lada Vesta car has a stove heater…

...designed to heat the car interior.
The stove is also actively used in rain or cold weather. The heater is also activated if necessary to quickly remove fogging from the windows or warm up passengers. In the “Lux” configuration, the car is additionally equipped with air conditioning, which creates a favorable temperature for a person.

The most common malfunctions of the Lada Vesta heater radiator: leakage, fan noise, engine vibration. The replacement process is not complicated, but requires care on the part of the repairman.

How the stove works on Lada Vesta. Device

1. The heater radiator is connected to the system main via rubber pipes. The heat emitted by the internal combustion engine is transferred to the heating system.
2. The heating system radiator distributes heat throughout the car interior using an electric fan.
3. A preset resistor online regulates the fan rotation speed.
4. The air flow is circulated and cleaned by a mesh and cabin filter (see diagram).
5. With the help of installed dampers, the driver and passengers regulate the air flow flowing to them.
6. The gearmotor rotates the damper based on the readings of the regulator and heater sensors.

How does the stove heat up on a Lada Vesta/XRAY? According to reviews, owners are almost 100% satisfied with the heater; in some cases there are minor comments on its operation. But during operation, for various reasons, its effectiveness may decrease. We will tell you about the main malfunctions of the stove and how to eliminate them.

Typical stove malfunctions

The most common problems with the stove on Lada Vesta are the following:

• the actual temperature does not correspond to the set one - low level of antifreeze (antifreeze), clogged radiator pipes or the formation of an air lock, which causes cold air to blow;
• vibration appears during operation - the electric motor is loose;
• insufficient air flow from the deflectors - clogging of channels and air ducts;
• the heater is inactive when it is activated on the dashboard - failure of the fuse (No. 14) of the mounting block.

Checking the stove fan

During the circulation of the air flow, dust particles settle on the surface of the impeller, as a result of which it begins to make noise and extraneous sounds appear.

To clear the fan blades of debris, it is necessary to provide access to the unit.

1. Unsnap the glove box.
2. Remove the filter element.
3. On the right is the furnace mechanism. We press the plastic clips and turn the impeller counterclockwise.
4. We remove the motor.
5. We wipe the drive with a rag.
6. Install the parts in reverse order.

Checking the stove dampers

Dampers are installed in the area between the deflectors and the fan. During operation, they fail, become deformed, and become damaged. Checking the serviceability of the damper on your own is quite simple: you need to activate the stove at maximum speed. If it doesn't blow well, it means the air duct is clogged. Change the damper positions. If you hear squeaking or noise, lubricate the moving parts with silicone grease.

Foggy windows when the heater is activated is the first sign of a ventilation problem. This problem provokes a sharp decrease in visibility on the road and an increase in the risk of an emergency. As soon as fogging is detected, check the condition of the ventilation; most likely, the air ducts are clogged.

Checking heating efficiency

Carry out prevention before the onset of winter. Be sure to check:

• heating the air;
• changing speed modes when switching the control lever, if necessary, replace the brushes of the stove motor;
• absence of extraneous noise, whistling in fan operation;
• the need for a time interval to warm up the air ducts.

Note to the driver! The left and right pipes must be at the same temperature. Otherwise, this is a sign of a malfunction of the heating system.

Instructions for replacing the heater fan Lada Xray

Before you begin dismantling the car heater fan, you will need to disconnect the ground terminal from the battery and remove the glove compartment.

1. Under the panel on the front passenger side, disconnect the block with wires (No. 4) from the fan.
2. We remove the fan by turning it counterclockwise, first pressing the latch (No. 3).
3. We install the Lada Xray heater fan in the reverse order.

Important! Before changing the fan on the XRAY, make sure that this is the problem. It may simply be a blown fuse or some strange noise coming from the transmission.

The stove in the Lada Vesta differs from similar devices on other AvtoVAZ models. The difference can be found not only in the design of the heating system, but also in the features of correction and control.

Replacing a stove radiator with your own hands on a Lada Vesta

Preparation of the workplace, necessary tools:

• rags;
• Phillips head screwdriver;
• flashlight to increase visibility;
• new radiator.

How to remove a radiator. Replacement sequence:

1. We turn off the engine, turn off the ignition, and squeeze the parking brake.
2. Open the hood and remove the terminal from the battery.
3. We grind off the antifreeze from the system. The plug is located at the bottom point of the radiator (key 17).
4. We remove the decorative trim on the instrument panel.
5. Remove the top decorative trim above the glove box. Let's take it out.
6. We dismantle the metal dashboard support on the driver's side.
