How to stop frost on windshield on the inside of the car?

[Triedaq]

I agree with shadowfax. I have had the same problem on several cars that I have owned that had to be parked outside. One car was my 1965 Rambler Classic 550 that didn’t have carpet–just rubber floormats. You could use my dog’s technique. He rides with his head out the window, but this method isn’t very comfortable in freezing weather. Other than trying Rain-x or keeping a window cracked open, you probably just have to live with the situation.
