Troubleshooting Hints

Perform before beginning System Diagnosis
1. Before attempting any electrical diagnosis, make sure that the Sunroof is not binding due to a mechanical failure.
2. Check PWR WDO Circuit Breaker.
3. Check that ground G302 is clean and tight.
4. If a motor's internal circuit breaker trips, it will not reset until voltage is removed from the motor.
