electric sunroof not sealing.
Had not opened the sunroof in 3 years. I opened it and as it slid backwards it made a loud banging/snapping noise. The sunroof opened completely. When I attempted to close it, it traveled normally to the 3/4 close position and stopped as it should but then moved very slowly the remainder of the way to the close position. In the close position, the rear edge of the sunroof would not raise up to meet and create a seal with the main roof. Any recommendations?
