Removing
To remove, follow the steps below.
1. Disconnect a wire from the negative plug of the storage battery.
Attention! When removing and installing the floor console on vehicles with the SRS system, do not allow the console to hit the SRS control unit and other elements of the system.
Pic. 18.13. Electric heater fan and resistor: A - cars not equipped with air conditioning; B - cars equipped with air conditioning; 1 - bottom cover; 2 - resistor; 3 - clamp; 4 - connecting air duct (cars without air conditioning); 5 - flange nut (25 Nm) or nut and washer (11 Nm); 6 - fan and heater motor; 7 - heater fan assembly; 8 - instrument panel; 9 - flange bolt (25 Nm) or bolt and washer (11 Nm); 10 - evaporator (cars equipped with air conditioning); 11 - electronic control unit for automatic compressor (cars equipped with air conditioning)
2. Remove the bottom cover 1 (pic. 18.13).
3. Turn away screws and remove the resistor 2.
4. Turn away screws, disconnect an electric socket and remove the electronic block 11 of management of the automatic compressor (cars equipped with air conditioning).
5. Remove the instrument panel.
6. Remove the clamps 3. To do this, use a Phillips screwdriver to push the pin inward (in the center of the clamp) to a depth of about 2 mm, then pull the clip out.
Attention! Do not push the pin further than necessary, as this may damage the spacer or the pin may fall inward.
7. Remove connecting duct 4 (cars without air conditioning).
8. Remove the evaporator 10 (cars equipped with air conditioning).
9. Turn away screws, disconnect an electric socket and remove the fan 6 with the electric motor of a heater.
Installation
Installation is carried out in the reverse order of removal, taking into account the following.
1. Before installation, check the serviceability of the electric motor and the heater resistor.
2. When applying battery voltage to the motor terminals, make sure that the motor shaft rotates. Also make sure that there are no extraneous noises and sounds.
3. Using a tester, measure the resistance between the terminals of the heater resistor connector.
Pic. 18.14. Location of pins on the resistor connector
Resistance between resistor connector pins (pic. 18.14), Ohm:
- 3–2 (LO) — 2,30;
- 3–4 (ML) — 1,10;
- 3–1 (MN) — 0,40.
4. Install the pin, then insert the clip into the hole.

5. Push the pin inward until its head is flush with the spacer (pic. 18.15).
