Power Window Switch: Description and Operation
The power windows are controlled by two-way switches integral to the power window and lock switch and bezel unit on the trim panel of each front door. A second power window switch in the driver side switch and bezel unit allows the driver to control the passenger windows.The power window switch for the driver side front door window has an Auto label on it. This switch has a second detent position beyond the normal Down position that provides an automatic one-touch window down feature. This feature is controlled by an electronic circuit and a relay that are integral to the Driver Door Module.
The power window switches control the battery and ground feeds to the power window motors. All of the passenger door power window switches receive their battery and ground feeds through the circuitry of the Driver Door Module. When the power window lockout switch is in the Lock position, the battery feed for the individual passenger door power window switches is interrupted.
A Light-Emitting Diode (LED) in the paddle of each switch is illuminated whenever the ignition switch is in the ON position. However, the LEDs for the passenger power window switches are extinguished whenever the driver selects the Lock position with the power window lockout switch.
