Hi guys, I really need help asap with my sunroof. I pressed the slide back button and it moved slightly then jammed! When I got out of the car, I noticed one corner of the glass has sunk below the roof level. Does the glass slide back under the roof or over it? It's never worked since I've had the car so I don't know how they open on the IS200. I've attached an image and I hope you guys can see it to advise me the best way to fix this. Cheers in advance
