Sunroof / Moonroof: Testing and Inspection

Sunroof Diagnosis Chart:

DIAGNOSTIC PROCEDURES
Before beginning sunroof diagnostics verify that all other power accessories are in proper operating condition. If not, a common electrical problem may exist. Check the condition of the circuit protection (fuses, circuit breakers or fuse links). Inspect all wiring connector pins for proper engagement and continuity. Check for battery voltage at the power sunroof control switches. If battery voltage is detected at the control switches, proceed with the tests.
