Driver Window Switch

When the ignition switch is in the RUN or ACCY position or retained accessory power (RAP) is enabled, battery positive voltage is supplied from the PWR WDO circuit breaker to the driver window switch. Ground for the switch is provided by G302. When the window switch is pressed in the DOWN position, battery positive voltage is applied to the driver window motor down circuit and ground is applied to the driver window motor up circuit causing the window to open. When the driver window switch is pressed in the UP position, the polarity is reversed, battery positive voltage and ground are applied to the opposite circuits and the window closes. In order to control the passenger windows from the driver door, the driver window switch assembly contains a separate window switch for each passenger door window. These window switches operate in the same way as the driver window switch, except that the applied battery positive voltage and ground must also pass through the passenger window switch to get to the passenger window motor.
