David, Thanks for the reply, Yes got the manual A/C the button lights up when I press it however there is no change in idle speed as the engine compensates the main 2 fans on the front dont turn and the compresser doesnt kick in so thats what led me to think the relay I went into Frauds today just to price up a new one just to see what i would be looking at if it was that and they wanted 65 euros ( I work in Germany)!!!!!! How would I go about testing he relay or bypasing it just to test it then i can move from there. Ive yet to check the dash lights just waiting to get a spare 5 mins missus is due to drop tomorrow!!!!
