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 power window control module to access an express mode of operation. When left front window switch is pushed to first detent or is held in down position for .3 second, module activates relay to apply full battery voltage to window motor. This provides current to quickly and fully open window.
