Passenger Door Power Window Switches

Each of the passenger door modules supply 2 power window switch signal circuits and a ground to the normally open contacts of their associated power window switch. When the window switch is operated, battery positive voltage flows through the circuits and the switch. The associated door module senses the switch activity, checks to see if conditions are correct for window operation to occur, and then supplies battery positive voltage and ground to its respective window motor to open or close the window.
