Windows: Description and Operation

LEFT FRONT POWER WINDOW
The left front power window is controlled by the Master Window Control Switch. When the Ignition Switch is in "START" or "RUN", battery voltage is applied to the Power Window Relay. The Relay energizes, supplying voltage to the Power Window Module and Master Window Control Switch. The Power Window Module has inputs from the Master Window Control Switch. The Power Window Module looks at the voltage levels on all three lines to determine which operation is requested.

PASSENGER POWER WINDOW
The Passenger Power Window may be controlled by the Master Window Control Switch or the Passenger Power Window Control. When operated from the Master Window Control Switch, the Passenger Power Window Motor receives voltage and ground through the normally closed Passenger Power Window Control Switch contacts via circuits PD10 (O/BL) or PD11 (LG/BK). The window moves up or down, depending on the switch position. When being operated from the Passenger Power Window Control, the Passenger Power Window Motor receives ground through the normally closed Master Window Control Switch contacts via circuit PD11 (LG/BK). Voltage to this Motor is supplied from the Power Window Relay and circuit PD06 (O/BK). The window moves up or down, depending on the switch position. The Right Power Window Control may be disabled by the Master Window Control Switch by moving the Passenger Window Lock Switch to on. This removes the ground from the Passenger Power Window Control.

REAR POWER WINDOWS
The rear power windows are controlled by the Rear Power Window Control. The Rear Power Window Motors receive voltage and ground through the Right Rear Power Window Control Switch contacts via circuits RW04 (R/Y) and RW05 (R/BK) for the left and RW02 (R) and RW03 (O/BL) for the right rear window. The windows moves up or down, depending on the Switch position.
