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.
