Drivers window came down on entering car and wouldn’t go back up, took it to a garage and they removed the door panel, cables from the window mechanism were detached and twisted , new mechanism fitted, window still not going up, new window motor fitted, garage has just called and the window now goes down but will not go up. Now the garage says it can only be the switch now. It has cost £700 so far and still not working. Do I now get a replacement switch??
