Power seats — description

1. The electric drive allows you to adjust the position of the seats without any effort. These models feature power seats that can be adjusted in six directions. The movement is carried out due to the presence of three reversible servomotors, which are enclosed in a single casing. The adjustment is controlled through switches located on the side of the seats. When acting on the switch, the polarity of the current on the servomotors can change, due to which the direction of movement of the seat changes.

2. Diagnosis can be done easily by performing the following operations.

3. Make sure there are no objects under the seat that could impede movement.

4. If the motor is completely inoperative, inspect the circuit breaker.

5. Turn off the engine to reduce the noise level, and, moving the controls to various positions, listen to the sound coming from the servos.

6. If the servos make unusual noise or do not operate, measure the supply voltages. In this case, the assistant must control the seat via switches. Operate the switches with the door open. If the interior lighting dims, inspect the seat rails for foreign objects.

7. If the servomotor does not work although power is supplied to it, remove it from the vehicle and test it using the connecting wires. If the serviceability of the servomotor is not confirmed, replace it.

8. If power is not supplied to the servomotor, remove the switch and check the power supply. If there is no power, examine the circuit between the fuse box and the switch. If battery power is supplied, check the voltage at the other terminals when moving the switch to the appropriate positions. If the switch is operational, examine the circuit between it and the servomotor for an open or short circuit.

9. After restoration, make sure the electric drive is working properly.
