Front Passenger Power Window Operation Without RPO AXC

The switch for the front passenger power window has 3 positions up, down, and express down and its position is a direct input into the passenger door lock/window switch, when the switch is pushed down or pulled up, the logic circuit within the 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 front passenger power window can also be operated from a switch on the driver master control. When the right front window switch on the driver master control is pushed down or pulled up, it's 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 passenger door lock/window switch which will provide power and ground to the window motor causing the window to open or close.
