Power Window Motor
Connect the motor terminals directly to the battery and check that the motor operates smoothly. See Fig 1 . Next, reverse the polarity and check that the motor operates smoothly in the reverse direction. Check the circuit breaker incorporated in the motor, after installing the motor and regulator to the body. Press the UP switch to fully close the window glass and continue to press the switch for 10 to 20 seconds. At the moment that the UP switch is released, press the DOWN switch. The circuit breaker can be considered good if at this time the door window glass begins to open within 60 seconds.
