Wouldn't the recirc system be better for removing humidity with the a-c? Less humidity coming in the car and removing more and more each time it recirculates. In defrost, the a-c is on..... just asking................:D I am no hvac guy, that is for sure.
I know there is a reason all cars have fresh air intakes, just wondering if I can get away with my idea because it wouldn't get used much.

From my own personal experiences I've seen the inside humidity rise from breathing inside of an enclosed vehicle under certain conditions. It was more noticeable if there were several people in the car and we had to crack a window open to clear the glass. Maybe I've misinterpreted what I'd seen but I do know that the intake of fresh air often dissipated the moisture that was on the inside.

When I raced the Duster last year my windshield began to fog. I tried to keep my windows open as long as possible before making a run. It got worse with the doors and windows closed with me inside. There is no fan/heater in the car and it was hot and humid that day.
