Windows fogging up.

Every time I get into my FX and there is any moisture in the air, the windows fog up completely. When I get out of the gym it's almost instantly. Anyone else have this issue?

Are your carpets or mats wet or very damp. This is probably the cause of it. In the winter I usually have my defrost on for a minute then I switch to either floor heat or to floor heat + defrost mode. I try to keep the mats dry and this prevents it.
 
Could it have anything to do with the recirculate button being on or off, thus causing the fresh air to come in or not in the cabin, even when the car is off?

So I have never had this problem, but recently I started working out quite a bit and if I do get in the car when I'm very sweaty, it fogs up the windows FAST. Climate control always is on auto. Windows rolled up because it's freezing outside.

I noticed once that the rear windows fogged up once when I had a full back seat of people on a cold day. Only thing that would seem to get rid of the fog in the rear was if I rolled the windows down, but didn't want to because it was freezing ass outside.

So in 1.5 years it has happened twice and once from a jam packed FX and another because I was sweating and breathing like a mofo...and it was very cold outside. I'm sure this is related...best way to overcome the fog? Even blasting air didn't seem to get rid of the fogs in the rear seats.
 
Condensation my friends... Especially after working out, you are breathing heavily and exhausting a ton of vaporized moisture into the air inside the car. In winter, all the surfaces within the car, especially the windows are well below the dew point and cause the vapor in the air to condense onto the surfaces.

Hot dry air is the best way to get rid of it as it will both warm the condense surface as well as "re-vaporize" the water droplets on the windows. If it's freezing cold out and I've been in the car for a long time, I will almost always leave the doors open for a little longer than normal when getting out to allow some of that water vapor to release. If you don't that's when you come back hours later to a car that has actual frost formed on the inside of the windows. And that's a ton of fun to deal with... :)
 
yeah we know it's not a problem...just wondering best ways to get rid of it....sounds like based on what Tim says is to just crank up the heat or open windows (which also makes it colder).
 
Your A/C system should dehumidify the air inside at any temperature so, even if the engine isn't warm enough to produce heat, turning the fans on will help with the condensation. I agree with Lance though - definitely check for a wet dog in the trunk area first.
 
I use Pledge to clean the inside of my windows and it keeps the fogging away quite well. (You know, because of all the macking going on and such)

Another jewel of info: Windex, which is ammonia based, is bad for tint. I use Windex on the outside and Pledge on the inside.
