Alrighty, My car has an ASC sunroof installed in it. All I know About it is that the trunk sticker says that it was installed with 12 miles on the car. Was this a dealer option? Anyway, I need a new headliner, but before i do that. I would like to lube the works and replace the seals in the sunroof. Has anyone done this before? How bad was it, and where can I get parts?
