I have noticed ever since I got my OZ from the dealer I have had a strange "fog" over the windows. Just yesterday I washed the car and only got to clean the drivers side windows, I even cleaned half of the front windshield. But when I got in the car later the fog was starting to come back, it seems to be coming from the vent. when I turn on the defrost it disappears though. Its almost like a smokers film but I dont smoke in my car...I was just wondering if anyone else has this problem or has any ideas

 

Prolly the plastic airing out. Takes a while for some of the great chemicals in plastic to air out. Or if you put any protectant on your dash like armor-all and got it in the vents that'll cause it too. The air itself could be dirty too I guess.
