You might have water inside your door? for the fogging, putting the defog with the AC really help clear it up fast.
I don't have this problem with my car and I washed it recently. I know the water goes through the door probably because I had my car treated for rust at the dealer and there are traces of this grease drooling on the side of the car. So I am guessing that some water goes into the door pannel and exit through the holes at the bottom of the door. Are these holes blocked on your doors?
