how does my truck have frost on the inside of the windows. Its like 14 deg but I have never seen this happen before any thoughts, thanks

 

run your defroster more to reduce the humidity in the truck... chances are you had warm moist air inside from breathing and whatnot... then after you parked for the night the windows cooled down and as the air cooled the moisture condensed out of the air and on the windows.

It happened to me once... I think it just takes an odd combination of factors to create.

Run defrost more often and it should fix it!

 

If your floor is the slightest bit wet it'll happen all day long
