Power window not working

Faulty switch: remove the switch on the other side and change the multi-pin connector. With the switch working, you should now be able to close the window.

No continuity in wire to motor: run auxiliary wire from battery (if there is no positive current) or to the mass (if there is no mass) to the power window motor. Start the engine.

The engine is blocked: remove the door lining. Hang the glass on the lifting rail and press firmly upwards. Fix the window in this position with strong adhesive tape or wedge it with a suitable piece of wood, for example. Of course, both are only forced decisions.
