I have a 2008 Chrysler 300 and I cannot for the life of me get the windows to not fog over! Defrost seems to help when its really cold but as soon as the inside heats up the back two windows get crazy fogged. I have tried everything. I have never owned a car that fogged over so bad. Anyone with larger cars with the same issue? My 2 door car doesnt have this problem. Whether we crank the defrost way up on hot or way up on cold the windows just are foggy... There is already too many blind spots in the car that losing those 2 windows to fog while driving is dangerous!
