The best fix for this problem is to put a rivet in the guide where it holds the bracket of the window. This should eliminate any further problems with the window coming out of its guide. I did this to both my windows about a year ago and havent had any problems. Gary Gore Activities Director DeLorean Mid Atlantic VIN 3360 << Hey List, I have a problem with my right toll booth window. The front end keeps slipping off the guide. The guide doesn't seem to be bent or in any other way different from the left one. I have slippped out the window and put it back in about four times, and every time I do I run the window up and down about 100 times to see what makes it slip off. Then, after the 100th time when it doesn't slip off, I put the interior trim back on and a few hours later when I try the window, it slips off the guide the 1st or 2nd time I operate the window. Has anyone else had this problem happen to their toll booth window, and how did you fix it? All help would be greatly appreciated. Thanks in advance. John >>
