  If it’s already cold, you don’t need to turn the AC on. The air will be dry once it gets warmer.

    Defrost setting uses the AC unit. Helps pull moisture out of the air

      Air conditioners pull moisture out of the air by making it colder, reducing the amount of moisture the air can hold. Its not doing anything if the air is already colder than the air conditioner can go. The air conditioner will only help if it’s 55F/13C or more, where it will only fog up if you live somewhere very humid.

        I don’t have a side in this but both my ‘93 Ford Escort and my ‘01 Ford Crown Victoria would turn on the A/C compressor if you hit the Defrost button for the windshield.

        The moist air freezes to the coils of the ac unit, which is than heated by air and drips out of the vehicle through a condensate drain.

        How do you not understand that basics of an air conditioner? It doesn’t just cool, it conditions the air.

        Wouldn’t it be more efficient to pass the cold dry air back over the hot side heat exchanger to increase its moisture caring capacity before blowing it at the glass?

        You know like a dehumidifier?

      I want to be able to blow hot air at my ice cold windshield in the -20°C Canadian winters, but American car designers are all like “oh you want to use the windshield vent? you must want the AC turned on!”

        This isn’t just an American car thing, non American brands do this as well. That’s because it’s a good idea. The heater core has way more capacity than the AC, so the air coming out of the vent will still be warm. But running the AC is still a good thing, because it gets the moisture out of the air.

        Without running the AC the humidity in the car shoots up and takes a while to clear, with the AC on the humidity stays controlled. This helps clear the windscreen sooner and helps with comfort in the car. It also prevents mold, which if you live in a cold but humid place, can be very annoying. It is very normal where I live to have the AC on in fall and winter, because otherwise the humidity inside the car is very uncomfortable and can easily cause mold all over the interior.

        Is -20°C regular winter temps for Canadians? It’s colder than that here in Minnesota

    This is wrong based on the assumption that it works the same in all areas of the world, but I’m not sure if this is -10 votes wrong.

    Especially considering some of the other posts I’ve seen on here and how they get voted on

    This can be correct in northern winters, with very high humidity this will only fog the windshield much worse.

      You cant have high humidity when its cold, doesnt depend on the location.

      100% humidity at 0°C is ~20% humidity at 25°, which is pretty dry.

        I guess cold is a relative term. I’m from Wisconsin- we can have 100% humidity at 65 degrees sooooo

    I’ve tried that. It only made things worse.
