I have a Ford Fiesta Zetec S (58 reg) and seem to have a problem with the air conditioning in that it only blows cold air when accelerating. If I stop in traffic or at traffic lights it continues to blow air but it's not cold air, it then begins blowing cold again once under acceleration. I've had the problem quite a while but it's become more annoying with the recent hot weather. I had the system re-gassed at the end of last year so don't think it can be due to this.
I've also just put it into a garage but the mechanic seems to think that it's just the way some cars are made, which seems strange and I just wondered if anyone else had experienced the same issue.
Any advice would be appreciated.
