Hi,

I ran into a similar problem on my 95. There is some sort of brace on the backend with a rubber seal alnog the to that somewho got gummed up. I pulled the shade and sunroof out using the instructions over at Bay 13 and noticed that somehow the two torx screws on the left hand side were in place but the connection to the slider was broken. I took the whole thing out since I didn't see the point in it and readjusted the glass after reassembly. Try looking around in there to see if something is binding and maybe its an easy fix. The dealers are in the business to make money ..so try saving a bit yourself by getting curious.

HTH
