Hi The rear window will not open, I've taken the cover off to have a look and the switches seem to be working ok but can't test cables as I don't have the right gear. Is it worth doing this or shall I just book it into the garage? The rear passenger windows have stopped working and I wondered if they are linked in any way? I checked the fuse which is fine. I assume I'm not alone in having these problems and wondered if anyone has any helpful advice. Regards JuBrux
