    Just the other day I was listening to this song by the Grateful Dead:

    "Sometimes the light’s all shining on me …

    Sometimes I can barely see …

    And lately it appears to me

    What a long strange trip it’s been. "

    It’s not about temperature, it’s about condensation and humidity. Turn on the AC regardless of temp (e.g. even if it’s cooler out and you’re blasting the heat) and the defog too.

    Always use heat. Anytime you have a fogged up window heat will cause that moisture to evaporate. Cold will always make the window cooler which causes more condensation.

      Air conditioning will remove moisture from the air while cooling the cab, so the condensation can only form on the outside, where you have wind and windshield wipers to wipe off the condensation.

    People in comments assume the heat or air conditioning even work.

    Air conditioning also rapidly reduces humidity, so that tends to be the ideal option.

    But if neither heat nor air conditioner work, well tough it out and roll the windows down…

    Remember to pull your sun visors down. My AC doesn’t stay charged so I have to rely on heat alone to defog windows. The visors trap the warm air.

      Defrost turns on the AC and blows cold air. That temporarily removes the fog and keeps the cabin cold. The alternative is to use max heat and let the hot air raise the cabin temperature which will help clear the fog.

      And it stays gone too. Using cold causes the fogging to return if hot air or the heater is used in the cold car. The defrost button is a myopic solution which ignores user comfort.
