On my 93 Accord my rear passenger side window will not roll all the way up, it stops about 1/2" from the top, just enough to let water it I took the door panel off last night, and I can't figure out what's wrong with it. The only thing is the two bolts that hold the window onto the frame piece will not tighten all the way. I tried, but the window will still move around a little. But even trying the window in slightly different positions, I still couldn't get the damn thing to roll all the way up without me pushing up as hard as I can, and it goes up only enough to keep most water out, but it still won't go all the way up.

Anyone have this problem? I am pretty mechanically inclined, but I can't figure this one out. I'm going to look at it again tonight after work, but any suggestions would help a ton! Thanks guys!
