Disconnect the sunroof motor (A) connector.
Ground the terminals as below table, and check that the sunroof unit operates.
When inspecting the sunroof motor operation, sunroof motor and roller blind motor always should be connected.
Make these input tests at the connector. If any test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, the sunroof motor must be faulty; replace it.
