Driver's Power Window Switch

Battery voltage is applied from WINDOWS circuit breaker to Retained Accessory Power (RAP) relay. RAP relay supplies voltage to driver's power window switch when ignition switch is in RUN position, and RAP is active. When driver's power window switch is operated to UP position, battery voltage is applied to power window motor. Power window motor is grounded through DOWN contacts of driver's power window switch to ground. Motor runs in order to drive power window up. When driver's power window switch is operated to DOWN position, battery voltage is applied to power window motor in opposite direction. Power window motor is grounded through UP contacts in driver's window switch to ground. Motor runs in order to drive power window down.
