How to Use Car Air Conditioning to Defog?

[MacSebastian]

Turn on the fan and cooling switch inside the car, and the cold air blowing onto the front windshield will quickly dissipate the fog, with a very direct effect. The biggest downside is that people inside the car will feel very cold. In the already chilly winter, the discomfort of blowing cold air from the air conditioning is hard to bear. If the fog inside the car is not heavy, you can open a small gap in the windows on both sides. This creates an airflow between the inside and outside of the car, reducing the temperature difference and causing the fog to disappear. Both cold and warm air have their pros and cons. If you're in a hurry to hit the road, you can use cold air as an emergency measure. In most cases, however, it is recommended to use warm air.
