Hello to all. I have a 1998 GS400. The sunroof has stopped working correctly. Now when I push the button to open the roof, it only opens about 3 or 4 inches. I have to keep pushing the button to open it fully. When I go to close it, the same thing happens. I took it to a Lexus only repair shop and they said I needed a new motor and a sunroof ECM. They quoted me $1147.33 for the parts, sounds high to me. Can someone out there help me out with some hints as to what I should do? Thanks, Pat
