Right then ive found relays behind coin tray on drivers side dashboard!
Seems i certainly have a faulty connection somewhere as when i wiggle the relay board the fans go on and off etc, cant see/work out exactly whats causing the faulty connection though!
For now i bave managed to jam a piece of hard plastic in there between front of relay board and back of coin tray mount which seems to have done the trick (for now)
So looks like its back to the dealers in morning as they have supposodly fixed this problem and charged me over £100 for the privelege so surely there work must be gauranteed?
Cheers anyway chaps
