Power Window Motor: Testing and Inspection

POWER WINDOW MOTOR INSPECTION

1. INSPECT MOTOR OPERATION

Left Side Door





(a) Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, check that the motor turns clockwise.





(b) Reverse the polarity, check that the motor turns counterclockwise.
If operation is not as specified, replace the motor.

Right Side Door





(a) Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, check that the motor turns clockwise.





(b) Reverse the polarity, check that the motor turns counterclockwise.
If operation is not as specified, replace the motor.

2. INSPECT CIRCUIT BREAKER OPERATION








Driver's Door
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the battery to terminal 9 and the negative (-) lead to terminal 10 on the wire harness side connector raise the window to the fully closed position.
(c) Continuity to apply voltage. check that there is a circuit breaker operation noise within approximately 4 to 40 seconds.
(d) Reverse the polarity, check that the window begins to descend within approximately 60 seconds.
If operation is not as specified, replace the motor.








Passenger's Door
(a) Disconnect the connector from the power window switch.
(b) Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 5 on the wire harness side connector and raise the window to the fully close position.
(c) Continue to apply voltage, check that there is a circuit breaker operation noise within approximately 4 to 40 seconds.
(d) Reverse the polarity, check that the window begins to descend within approximately 60 seconds.
If operation is not as specified, replace the motor.

Rear Door
See Passenger's Door above.








3. INSPECT MOTOR CIRCUIT
(a) Disconnect the connector from the motor.
(b) Connect the connector to the master switch and power window switch.
(c) Inspect the connector on the wire harness side, as shown.
If the circuit is not as specified, inspect the circuits connected to other parts.
