It can only be four things: 1. Window motor 2. Window regulator 3. Window switch 4. Wiring to the motor/switch Number 1 or 2 is most likely the cause of the problem. If you can hear the window motor working when you push the window up button but the window is "stuck", the regulator is probably bad. If you hear nothing when you press the window up button the motor is likely the culprit.
