I need to share this one for all you 88-91 guys. I commute to work with a buddy and it was my week to drive. He'* only going in and going home with another buddy...cool.
I hop in the car in the afternoon, gorgeous day drop the windows.....except the drivers window goes down a 1/4 inch and stops, I know enough not to force it..so up and down a few times...only 1/4 inch...hmmm that is the door I changed the mirror on so maybe something moved and is in the way.
Get home...take panel off and check track etc. 1/4inch only and nothing blocking it anywhere..WTF???? Then a thought hits me and I pull the weather strip away from where the anti-theft stickers are on the back of the window and zip..right down and right back up.
That morning while waiting in buddies driveway I decided to dispose of the sticker...the goo was still there and that was enough to stop the window dead. Goo gone, 5 seconds and the window was fixed.....DOOOOOH!
