Power Window Motor: Testing and Inspection
INSPECT POWER WINDOW REGULATOR MOTOR ASSY LH (DRIVER SIDE)
a. Check operation of the regulator motor.
1. Apply battery voltage to the motor terminals.
2. Check that the motor rotates smoothly.
If the result is not as specified, replace the motor assy.
b. Check operation of the PTC inside the regulator motor.
NOTE: The work must be performed with the power window regulator and door glass installed in the vehicle.
1. Set an electrical tester DC 400 A probe to the wire harness of terminal 4 or 5.
NOTE: Match the arrow mark of the probe with the current direction.
2. Fully close the door glass by operating the power window switch and keep the door glass there for approx. 60 seconds.
3. Try to operate the power window past the fully closed position using the power window switch and measure the time until the electrical current changes into 1 A from 16 to 34 A (Inspection of current shut-off)
Standard: 4 to 90 seconds
4. Check that the door glass goes down when the power window regulator switch is pushed DOWN.
If the result is not as specified, replace the motor assy.
INSPECT POWER WINDOW REGULATOR MOTOR ASSY RH (FRONT PASSENGER SIDE)
