Hi got the above motor with 25k on the clock. All of a sudden everytime I go to the car now and switch on the Air Con button is lit ! No problem switching it off but next time there it is again !!! Any ideas ? is it something I've done ? altered a setting somewhere ?

Any help gratefully received

It comes on automatically if you have your fan set to windscreen it’s to help with de-misting or defrosting  

DOH !..........what an idiot I am......you would think after five years of ownership I would have known this.....its an age thing !  Cheers Graham

I find this feature very annoying. I would prefer it if I could make my own decisions when to turn it on, like in my previous 2007 fiesta. Does anyone know if that can be disabled using forscan? 

I think even Forscan would be confused by the HVAC system in current Ford Fiestas. After a year and a good look at the book I still have to rely on inspired guesswork from time to time.

if set to windscreen (white screen button) it should remain off, however if set to max demist (orange screen button) it will switch on ac/front screen/rear screen and set fan speed to max to help rapidly demist the car
