How to Defog the Front Windshield?
2 Answers
Methods to defog the front windshield of a car are as follows: 1. If it's a manual air conditioning system, turn on the front window defogging mode, adjust the fan speed to the maximum, turn on the AC switch, and set the temperature to the lowest. The fog on the glass will disappear shortly; 2. Some models are equipped with rear window and electric heating, as well as external rearview mirrors. Just click the switch, and the fog will be eliminated in about one minute; 3. If it's an automatic air conditioning system, generally, you only need to press the one-touch defrost button. After pressing it, the air volume will automatically increase to the maximum, and the external circulation will be turned on, making it both practical and convenient.
When encountering foggy windshield, I usually press the defrost button with the fan symbol, while turning on the AC and external air circulation. This directs cold air to focus on the windshield, clearing the fog within minutes. Using warm air in cold weather also works, though it may initially worsen the fog—just wait 3-5 minutes for it to take effect. Another method is applying anti-fog spray; evenly wiping it on the glass can prevent fogging for weeks. In emergencies, slightly opening windows helps balance interior and exterior temperatures. Lastly, remember to regularly replace the cabin air filter—a clean one dehumidifies faster, making rainy-day driving much safer.
