Power Windows

The power windows can be raised or lowered from the Driver's Door Module (DDM) or the individual door switch. The DDM has a lock out switch that prevents the windows from being operated from any switch except the driver's door. When the switch is pressed, it also shuts off the individual door switch LED's. A feature of this system allows the windows to be operated from any window switch for 45 seconds after the ignition is turned off, provided a front door is not opened. Another feature is the Express Down on driver door only. When the driver presses the down switch to the second detent, the window will travel all the way down even if the switch is released. To stop the window travel, simply press the switch momentarily in either direction. Twelve volts are provided on the rear window motor circuit on both the up and down circuits. The appropriate door module supplies this voltage. When the rear switch is pressed, the supply circuit to one side of the switch is opened and ground is provided making a complete circuit and therefore operating the window motor.
