Closing to the Fully Closed Position

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

To close the power sunroof from the following positions:

Holding the sunroof switch to the close position will cause the sunroof switch close signal and sunroof switch close vent signal circuits (12 V references) to be pulled to 0 V. The constant low inputs to the sunroof control module indicates a close request. As the close request has been initiated, the sunroof control module will drive the motor to the closed position until the limit switch closes, indicating a flush close position. As the sunroof glass nears the closed position, the wind deflector will retract, and the rear sunroof glass will raise slightly, then seats to flush with the roof panel. To close the sunshade, this will have to be manually slid closed.
