Re: Farmont EL heating issue - is this normal?
recirculated air needs the air con as it dries the air.
Recirculated air tends to build its moisture content, which compounds fog./mist on the inside.
Try this on a day your car is misted up inside, use FRESH air, and see how ling it takes to clear the inside...turn the aircon on and see how quick it dries.
I don;t have auto aircon, but have driven vehicles that do, and the difference is amazing..esp in that you dont have to think about it
