Sunroof no longer operating due to mechanical manfuction
When openin all the way i have to push the sunroof down to open it
Goopy, tar like adhesive, bits of gasket material breaking loose, jamming between sunroof lid and roof. Scratched sunroof paint; squeaking. Over time, I think most of the broken gasket material has come out, but the sunroof still squeaks and something still scrapes the paint. Terrible design!! I would like to try to fix myself someday.
sunroof does not open or close have to manually crank open the rook or pop top what is the solution
