Today, when it was first warm day, suddenly my sunroof dont open up properly, but after trying and trying again it opens. After going to carwash, comes out that my sunroof dont close anymore At last i must close it manually. When the car was washed, one guy came there and told me that my sunroof is not maintenanced properly and there are some cables which pulling the sunroof are dried-up. Anybody knows how can i grease them or something?
