Should You Use Cold or Warm Air on Rainy Days?
2 Answers
On rainy days, you should use cold air. The method of using car air conditioning is as follows: Distinguish colors: The blue button on the left side of the car represents cold air, while the red one represents warm air, and the middle one represents a moderate temperature; Rotate the button: To turn on the cold air, adjust the left button towards the blue area. When you want warm air, adjust it towards the red area, then press the AC switch. The middle button controls the fan speed, and the rightmost adjustment mode can be set to blow air only to the feet, hands, or windshield, or both sides simultaneously; Identify temperature: The white line on the left adjusts the temperature. When it feels too warm, you can adjust it to the middle. To turn off the air conditioning without turning off the fan, simply close the middle fan button.
I remember one rainy day while driving, the car windows suddenly fogged up, completely blurring my vision, which scared me into pulling over immediately. At first, I thought turning on the cold air would solve the problem, but the fog dissipated very slowly and left the car interior freezing cold. Later, someone suggested using the heater, and it made a world of difference—the warm air quickly dried the fog on the glass, clearing the view in about 30 seconds. The principle is simple: rain creates a significant temperature difference between the inside and outside of the car, and the warm air heats the glass surface, evaporating the moisture. Now, this is my go-to method: as soon as I get in the car, I set the air conditioning to warm air, direct it toward the windshield, and turn on the external circulation to let fresh air in, preventing moisture from building up again. Don’t worry about fuel consumption—this method uses much less energy than cold air and ensures driving safety. On rainy days, visibility is everything, and warm air is definitely the best choice—it instantly clears the fog without making you shiver. I’ve been driving for years and never had an issue.
