Sounds like someone did a DIY and whacked the sunroof shade back on the wrong side of the sunroof driver... I did this yesterday and it won't allow you to move it back but it goes back with the roof but not all the way into the roof.That is the problem, it wont go back more than 2 inches. It was like that when I bought it used. It goes back with the glass when it is opened, but comes back up with it when it is closed. I would like to fix it, but I don't want to brake anything in the process.
