I have a 1991 5.0 and its a great car, thats a given... but one of the only problems i have with it is that when i push the button to have the window's go down they screech all the way down and then all the way back up. I took apart the panel for the door and tried to get a look in there to see what was going on but i couldn't find anything. Has anyone heard of something like this before? I would much rather try to fix it myself than take it to a dealership, no offense to them but i prefer to work on my own car. Any help would be great
