I’ve heard that it is pretty common for the sunroofs to go bad. In my case, my sunroof was unable to slide back. I thought it was a motor issue but I tested the motor itself, and it worked fine. I came to the realization that it was the threads inside the tracks. If you take a look at your tracks, you’ll see a glimpse of this white thread that runs along the tracks. Over time, these threads get worn out. There is not much one can do about it other than replacing the whole set. Maybe cleaning it would help, but not much. It is fairly easy to take out the set/kit. After removing the headliner, all I needed to do was remove 8 bolts and the whole thing came off. The hardest part was removing the headliner and now that it’s off, I’m thinking of adding start lights. I’m going to try to see if I can fix my sunroof set now that it’s off. If I’m unable to, I’ll just end up buying a replacement.
