mines been misting up pretty bad too but theres no damp in the car anywhere. I always have my blowers set to the windscreen position and never out of the dash vents towards you. The other day i switched it to them because i was freezing and ive not had mist since! Ive switched it back to the windscreen position and all is good, absoloutly no mist now, mabie some moisture was in those vents or something? give it a try it might work for you too
