    Brian,

    Think of it this way. In winter the air outside is bone dry. The air
    inside your vehicle is dripping wet by comparison because of wet floor
    mats, breathing, etc. If you recycle the inside air, you have a steam
    bath condensing on the cold windows. Turn off the recirculator and pump
    dry, heated air into the cabin to clear the windows.

    When it's really cold, the AC compressor won't run until it's nice and
    warm under your hood anyhow, but using the AC is better suited for
    Malaysia, where it's HOT and humid, not cold outside and humid inside.

    If I'd have had an owner's manual for my old Volvo, maybe I would have
    figured out the part about the RECIRC button a few winters sooner . . :-(

    ++++ Most of the original Hyundai cars had a BAD condensation problem
    too +++

    You should be running your AC in the winter anyway just to keep the seals
    pliable. Don't worry about the little bit of extra gasoline you're using.

    Do your vehicles have a manual recirc mode? If so perhaps
    you are operating in recirc mode, when you should be on
    outside air.

    It doesn't on my 2000 Acura TL or my '96 Odyssey. Must be a new for '01
    thing.

    Almost all cars since the 1980s at least, run the A/C to dehumidify the air
    before warming it. Makes the defroster more efficient.

    There is a ventilation setup position on Honda '04 Accord where you can
    defog the window-shield and warm up your tootsies at the same time.
    Does anybody know if that will turn on the AC?

    Yes - in the defrost position. Not in the one that directs air to both the
    feet and the windshield.
