It's cold here in Canada, when I get in the Bronco the windshield fogs up and then the fog turns to frost. It takes about 30 minutes for the frost to thaw completely which is pretty annoying. Does anyone else have this problem? My 1980 doesn't have AC so I can't use it as a dehumidifier. Do you turn your windshield heater/fan on right away or let the truck warm up first?
