Memory Reset Procedure
WARNING: This page is about a different car, the 2003 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
If the battery is disconnected, or the sunroof motor harness connector is disconnected, the sunroof motor memory must be reset. To reset the sunroof motor memory from any sunroof position (full open, partially open, closed, partially vented, and vented), push and hold the sunroof switch in the forward (CLOSE) position until the sunroof vents in the full-up position. This resets the sunroof motor memory and now the sunroof will operate correctly.
