crew cab rear window

Depends what is wrong with it. If you have a faulty switch, that is the easiest repair. However, most times you have a motor that draws too much power, extremely dry glass runs that the glass binds on causing significant drag and motor wear, or a window regulator that is binding or broken. Aside from a switch replacement or lubing the window runs, you have to get inside the door panel and test and inspect. Most of the time a do-it-yourselfer will seek assistance as these repairs are not easy. Good luck.
