Searched for this and didn't find anything, so let me know if this is a dup.
Wondering if anyone else has this problem. I live in Southeast Iowa. Been mostly in the teens and twentys morning and evening.
My windows are fogging very badly. I drive 30 minutes to work. I have to put it on defrost (not half windshield/half floor) and turn the fan all the way up. This is more than annoying to say the least. This keeps the windshield clear and most of the front side windows. They stay fogged up around the seal. The back windows stay fogged and the rear window requires defrost to be on constantly.
The weird thing is that when it first started, the temps outside were cold, but temps we had already seen before. So I cleaned the windows (I use Invisible Glass) just in case a film was on there. It seemed slightly better, just barely, for a day or two, then back to being badly fogged.
And side note is that my mileage is still not great after 4500 miles on my 1.8L. struggle to get 28 mpg with 90% highway driving every day. Comparing to previous cars, I would expect to be getting 30-32 in the cold temps. Hopefully this comes up in the spring.
