1. Check the circuit breaker. If the power window circuit breaker has tripped, reset it. The circuit breaker is usually located in the fuse box, which is typically under the dashboard or in the engine compartment.
2. Check the window switch. Make sure that the window switch is in the "up" position. If it is not, press and hold the switch in the "up" position until the window is fully raised.
3. Check the window motor. If the circuit breaker is reset, the switch is in the "up" position, you may need to jump start your vehicle, and the window still does not move, the window motor may be burned out. You will need to replace the window motor.
4. Check the window regulator. If the window motor is working but the window still does not move, the window regulator may be damaged. You will need to replace the window regulator.
5. If the window is still stuck, you can try to pry it up with a pry bar or a flat-head screwdriver. Be careful not to damage the window or the surrounding trim.
6. Once the window is up, you can try to reset the power window switch by turning the ignition off and on again. If the window still does not work, you will need to take the vehicle to a mechanic for further diagnosis.
