Hi all, I've recently purchased a 2003 A4, and the window cluster on the drivers door Isn't working properly , so brought a new one from ebay, thinking it would a few screws , but no Can't see an obvious way in, so thought best get some advice before hacking at it with my screwdriver, if anyone can tell me the best way to go about it without causing any damage, I'd be very grateful. In advance many thanks. Karl
