I see weird white fog showing on my windshield when I drive in the morning and rainy weather. The fog also shows on my dads 2002 Legacy Wagon. When a fog goes on. Its even hard to remove it using wiper blades. The fog is on the outer side of the windshield and can be only removed by blowing hot air from the inside, which is a *************** when its hot outside. Could somebody please explain this problem to me, because I have no idea what it might be.
