The master window switch has an Auto-Down feature. Actuation of the master switch to the second down detent position will move the drivers side window completely down. The electronic switch will automatically disconnect the motor approximately 1 second after the window bottoms out. Failure of the electronic switch to detect stall current, will cause the switch to disconnect after approximately 15 seconds of operation. The auto down function can be canceled by any movement of the switch.
