Normal Operation
Under normal operation, the accessory delay relay supplies voltage to the master window control switch. The master window control switch supplies the ground circuit for passenger rear window operation. On vehicles not equipped with RH front window one-touch up/down feature, this ground circuit is shared with the LH front window motor.
This pinpoint test is intended to diagnose the following:
- Accessory delay relay
- Circuit breaker
- Wiring, terminals or connectors
- Window control switch
