Power Windows / Weather Stripping

I have an issue with my windows, 1981 Corvette. They switches and motors seem to work fine, they go up and down easily. They wont start to go down if the doors are closed unless I give the Window a little pressure downward, and if the doors are closed they wont roll up all the way either, they stop when they hit the weather stripping about 1/2 inch from the top. I can open the door and they roll up all the way and then I shut the door and its a good seal, accept right at the back of the window where there is always about a 1/4 inch gap that sucks air. Anybody got any clues as to why it doesnt seem to have enough power to start and finish on its own, or what may be the cause of the gap at the rear? I though may be the T Tops needed to be adjusted down in the back but I read in the maunal that they are supposed to sit up higher and not to adujst them. I also wondered if some of the nylon window roller bushings are worn out etc. I have replaced all of the weather stripping.

Door glasses are not adjusted properly. Sounds like they begin to rub on the weatherstripping as they near the top of their travel. They are supposed to snug up, but not so tightly that they bind. Do you have the AIM? There is a page of instructions on how to adjust the door glasses in the AIM.

I took my motors out and cleaned all the old grease out of the regulator areas and put new grease in. You might be supprised how that sped them up.

AIM=assembly manual.

your glass is a bit out of alignment. the adjustment isn't difficult and is usually needed when new weather stripping or glass has been installed.
