Power Window System: Description
Power window system uses a permanent-magnet motor to operate each window. Motor operation is controlled by a master switch assembly alone, or in combination with individual window switches. Window is raised or lowered depending on polarity of current applied to window motor.
Some models use a control module to access an express mode of operation. When left front window switch pushed past first detent, module activates relay to apply full battery voltage to window motor. This provides current to quickly and fully open window. If window switch is pushed to UP position during express down mode, window will stop. When window reaches full down position, motor stall is detected by master switch, cutting off power to motor.
Rear window lock-out feature disables rear window switches, allowing only master switch operation of rear windows.
