So yea the other day I was takin the stereo as usual. Showin off u know how it is lol. Got outof the car and looked at the sunroof cause it was closed and it was lifting BIG TIME like almost like opening it. Well now when I have it open. It opens alot slower than it did and I hear metal on metal HEAVY rattling. Anyone else do this or know wut could have been possibly knocked loose?

 

lol only one way to find out....gotta pull out the headliner. lol or you may be able to look between the headliner and roof where the sunroof slides back into and see if you can see anything

 

If it's a factory sunroof, you should be able to remove 4 screws and lift the glass out. I had to adjust my glass when I first purchased my Bravada because it would not retract all the way. First I removed the glass to see if it would then retract to make sure it was just an adjustment issue and not a track issue.

IIRC, they are torx screws...
