As stated on p1, AC is your dehumidifier. This is why your AC compressor is running anytime you have the defrost on. The dry air will clear your fogged windshield much faster than regular hot air. It will also help keep the windows clear after any precip that was on you starts to evaporate when the cabin warms up. - The AC in my Subaru is broken, so on snowy mornings I run the defrost while scraping (blowing regular warmish air), which takes forever to clear the fogged window, only to have it come right back when I get in the warm cabin. Basically I gotta carry a towel or drive with my window down. Cool story bro, I know.
