Power Sunroof Inoperative One Connector System
Diagnostic Aids
The sunroof motor and sunroof module are integral parts of an assembly and are not serviced separately.
If voltage is not measured on the sunroof switch open signal or sunroof switch close signal circuits, the fault could be in the accessory voltage circuit, battery positive voltage circuit, or sunroof motor/module ground circuit. If the sunroof motor/module is not being powered, neither will the sunroof switch signal circuits.
