Power Window Motor: Testing and Inspection

Driver's door:
INSPECT POWER WINDOW MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, and check that the motor turns clockwise.
b. Reverse the polarity, check that the motor turns counter-clock wise.
If operation is not as specified, replace the motor.




Passenger's door:
INSPECT POWER WINDOW MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, and check that the motor turns clockwise.
b. Reverse the polarity, check that the motor turns counter-clock wise.
If operation is not as specified, replace the motor.




Driver's door:
INSPECT POWER WINDOW MOTOR PTC THERMISTOR OPERATION
a. Disconnect the connector from the power window motor.
b. Connect the positive (+) lead from the ammeter to terminal 1 on the wire harness side connector and the negative (-) lead to negative terminal of the battery.
c. Connect the positive (+) lead from the battery to terminal 2 on the wire harness side connector, and raise the window to the fully position.
d. Continue to apply voltage, and check that the current changes to less than 1 A with 4 to 90 seconds.




e. Disconnect the leads from terminals.
f. Approximately 60 seconds later, connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2, and check that the window begins to descended
If operation is not as specified, replace the motor.
