Hi There
Thank you for your reply, I have ordered a manual

. Have taken the assembly apart as much as I can and it seems that the mechanism has come adrift hence why the cable snapped, so one side is up and the other is down. further problem is the screws that hold the glass in wont come out as one appears to have been cross threaded and the other has been over tightened hence the head is now not usable. very annoying. Any pointers on where would be a good place to look for second hand parts for these cars would be much appreciated
