Ok I own a 86 Ford Bronco and every since I got it the window never worked but now I plan on fixing it. What the window does is not go up or down. I hear the motor but nothing happens. I've been told it's off track by one person and it's the motor by another person. I mean I pull itup and down by hand when I need the tailgate open and the whole window goes down not just one side so I thought maybe it's not off track but I could be wrong. So my question is what do you think it could be because I am about to go ahead and replace the motor just in case anyway.
