I have a 2001 S40 that has a moonroofthat seems to like to make noise. The sound is not coming from one specific area, but instead the whole glass panel seems to be loose. The sound is more of a muted creak/groan/rattle sound. It seems to be worse when it is cool and when i am going below 30 MPH. Has anyone had any similar problems like this? Any ideas or fixes would be appreciated!
Thanks!

Slide the glass all the way back and try to put a little bit of grease in the tracks.
