Windows: Description and Operation

Power Window System





Power window system allows front and rear side door windows to be operated electrically. Each window is raised or lowered using a bi-directional electric motor attached by continuous cable to window regulator. Window motors are controlled by switches mounted on front and rear side doors. Driver's door contains main power window switch assembly that controls each of other three doors.



A DC motor raises or lowers the window at each door; whether the motor raises or lowers the window is determined by the polarity of the voltage applied to it. A switch located at each door panel controls the voltage applied to that door's motor. In addition, the driver's Master Power Window switch has three additional switches, providing control for all four windows. This Master Power Window Switch also has a provision for the automatic lowering of the driver's window. This will occur when the driver's window switch is depressed fully.
