Try running the window with the panel off and maybe you can see the problem. The motor and regulator are attached with rivets to the inside of the door. If you have to replace one or both, you have to destroy the rivet heads with a drill and cold chisel and pull the motor/regulator unit out through the opening. I think there are four rivets -- top and bottom of the track and two for the regulator.
If you have to separate the motor and regulator, there are three smaller rivets holding them together. Replace all rivets with bolts to reinstall. Before removing the regulator and motor, you'll also have to tape the window glass in the frame and remove the two bolts holding it to the regulator. Replacement motors aren't cheap, about $45, but are easily available. I guess if you had to replace a regulator you might have to get it from the junkyard.
