What kind of air should the AC blow to defog when coming out of a garage in summer?

[LaBrielle]

In summer, when fog appears after driving out of an underground garage, you need to turn on the car's defogging switch. Turn on the cooling to lower the interior air temperature to match the outside; or turn on the heating to equalize the temperature outside the glass with the interior, i.e., using hot air. Scientific principle: The fog outside is caused by the temperature difference between the inside and outside of the car. When the cabin temperature is lower than the outside, moisture condenses on the outside of the windshield, forming fog. The main function of fog lights: Fog lights are installed at the front and rear of the car. Because visibility is low in foggy conditions, limiting the driver's line of sight. The lights can increase visibility distance, especially the strong penetration of yellow fog lights, improving the visibility for the driver and other traffic participants, allowing approaching vehicles and pedestrians to spot each other from a greater distance.
