Diagnosis And Testing - Power Window Switches
The master window switch has an Auto-Down feature. Actuation of the master switch to the second down position will move the drivers side window completely down. The switch will automatically disconnect the motor approximately one second after the window bottoms out. Failure of the switch to detect stall current will cause the switch to disconnect after approximately 13 seconds. The auto-down function can be canceled by any movement of that switch.
