POWER WINDOW MOTOR INSPECTION

id091200800800

Front Side

1. Apply battery positive voltage and connect the 

ground to power window motor terminals E and F, 
and then inspect the power window motor 
operation.

• If the power window motor does not operate 

as indicated in the table, replace it.

Caution

• If the power window motor temperature is 

high, the motor may not rotate due to the 
motor internal bimetal function. Leave it 
untouched for about 3 min to cool it 
down, then reinspect.

2. Connect the battery positive voltage to power window motor terminal D and connect terminal C to ground.
3. Operate the power window motor and measure the voltage at terminals A and B.

• If there is any malfunction, replace the power window motor.

Voltage

• Pulse: max. 12 V/min. 0 V
