Frost on outside of front window
 
ive had this annoying episode happen more then twice now. On very hot and humid days I get frost on the front and some on side windows. The a/c is on. My wipers won’t even remove the problem. I called my dealer and a service guy asked if I was using the a/c and defroster at the same time. I said I was, only because I thought it would help the problem. Last night it was so bad that I could hardly see out of the front. Any thoughts?

Frost? As in ice crystals? Sorry but no way your AC is making those windows cold enough to form frost. Fogging the windows yes, frost no.

If you have the AC mode set to blow cold air on the windshield, or if the defroster is on, and it's warm and humid outside, you can get some fogging of the windshield in the vicinity of the dash vent on the outside. Your wipers would clear that right off.

Turn the temperature up so the air isn't so cold blowing on the windows.

Turn the thermostat to half way between cold and hot. Turn on the defrosters. Happens to me all the time in Florida, but the humidity usually burns off by 9am.

my pickup does the same thing,,, fogs up the windows,,,, just the difference in temp and humidity from inside to outside.
