Im also getting this misting problem with my 57 plate c-max!, if its raining the only way to clear screen is to turn on a/c, it automatically comes on when the dial is on the front windscreen. this is really annoying my previos cars never had air con and they demisted the screen fine after a few minutes. i didnt expect this on a new car, could the air filter need changing? i try not to use a/c to save on fuel, does anybody know if one of the other settings is better for clearing the windows as a whole and not just the windscreen, how about anti mist fog window cleaners would they work. im
