Passenger Window Operation

The driver and passenger window switches each receives a constant ground source and the passenger window motor is supplied battery voltage through the accessory voltage supply circuit . The up, down and express signal circuits are shared between the right front switch on the driver window switch and the passenger window switch. The logic circuit within the window motor monitors the up, down and express signal circuits which are normally equal to B+ voltage. When the right front switch is used on the driver window switch or the passenger window switch is used, the contacts close causing a voltage drop within the appropriate signal circuit. The window motor will detect the voltage drop and will command the window to move in the direction requested.
