Rear Passenger Power Window Operation

The rear passenger power window switches have their own battery voltage and respective grounds, when the switch is pushed down or pulled up, the logic circuit within the rear passenger power window switch will provide power and ground to the window motor causing the window to open or by reversing polarity, the window will close.

The rear passenger power windows can also be operated from switches on the driver master control. When the rear passenger window switches on the driver master control are pushed down or pulled up, their position is signaled to the BCM via the driver door lock/window switch. When the BCM receives this command the appropriate signal is sent to the rear door window switch which will provide power and ground to the window motor causing the window to open or close.
