How to Deal with Foggy Windows When Using Air Conditioning in the Car?

[DiAlessandra]

Here are the methods to solve the problem of foggy car windows when using air conditioning: 1. Blow cold air: In cases of light fogging, you can appropriately open both windows to allow air convection, which eliminates the temperature difference on both sides of the windshield, making it difficult for fog to form. Alternatively, turn on the cold air from the air conditioning, which can quickly remove the fog in a short time. The advantage of both methods is their quick effectiveness, but the downside is that they are not suitable for prolonged use in cold weather or during rain or snow. Otherwise, while the fog may be removed, the occupants might catch a cold from the draft. 2. Blow hot air: Blowing cold air provides a quick but temporary solution, whereas blowing hot air can fundamentally solve the issue of foggy windows. The fog will not return after the hot air is turned off, nor will it make the car occupants feel even colder in the winter. However, the biggest drawback of blowing hot air is its slow effectiveness, requiring a long wait to see results. Additionally, using the heater while driving consumes more fuel, making it a bit costly.
