Do you hear the motor going inside the door when you operate the switch? Its most likely the plastic guide at the bottom of the window that broke. It's a common problem and there is lots of info when you search. The door panels are slightly tough to deal with. You have to jiggle them around quite a bit during removal and installation. Just take your time. I replaces mine with washers and a nylon roller, but the genuine replacement part is cheap enough.
