Supercharger location
- 1 - supercharger housing;
- 2 - supercharger engine;
- 3 - fan wheel.
The photo shows the location of the supercharger in a car with air conditioning.
When the glovebox is dismantled, the blower motor with fan wheel is available (2). It is inserted into the duct (1) from below.
Here, the additional resistance of the supercharger (2 - next to the thermal fuse) removed from the mounting hole in the box (1) supercharger. The arrows show the plastic retaining springs.
The blower motor operates at four speeds, which are set by a rotary switch «Air supply and blower» on the dashboard. Different speed steps are achieved by connecting resistances of different sizes (or their serial connection). The resistors are connected to the ground wire of the supercharger motor. Positive current supply (through the fuse) remains constant - only ground contact «getting better» or «getting worse».
Troubleshooting the blower motor
1. If the air blower does not work in any of the switch positions, then first check the corresponding fuse (table in chapter Electrical equipment).
2. If, despite a working switch, the wipers also do not work, then the cause is the X-contact unloading relay.
3. Checking the blower motor: completely dismantle the glove box (chapter Salon).
4. Disconnect the two-pole connector in the wire to the blower motor, connect two auxiliary wires to the now free engine contacts: from the battery plus to the contact to which the red wire was connected, and from the battery minus to the contact to which the brown wire was connected.
5. If the blower motor is OK, it should now rotate at full speed. If not, replace it.
6. If the drive does not operate at all speeds, then there may be a defect in one of the resistances.
7. Dismantle additional resistances, carry out visual control. If one of the resistors is burned out, replace the entire resistor support.
8. If the additional resistances are in order, then along with a violation of the conductivity in the wire, the rotary control in the dashboard can also be the source of the malfunction - replace the entire heating control device.
Removing the blower motor
1. Completely dismantle the glove box (chapter Salon).
2. The blower motor is inserted into the air duct to the heating from below.
3. Disconnect the blower motor lead wire connector and remove the wire from the bracket.
4. Raise the locking lug on the left side of the housing above the latch and remove the air blower housing by turning it to the left (counterclock-wise).
Dismantling the additional resistance of the air blower
1. Dismantle the glove box (chapter Salon).
2. Press up on the two plastic retaining springs at the bottom of the additional resistance mounting plate.
3. Lift up the mounting plate and slide it down. If necessary, loosen the adhesive bond.
4. During installation, make sure that the main resistance board is fully seated in the duct. If necessary, seal it with sealant.
