Solutions for foggy car windows: For manual air conditioning, you can turn on the front window defogging mode, set the fan speed to maximum, turn on the AC switch, and then adjust the temperature to the lowest. The fog on the windows will disappear shortly. Some car models are equipped with rear window electric heating and external rearview mirror heating. Simply press the relevant buttons, and the fog will be cleared in about a minute. For automatic air conditioning, usually just press the one-touch defrost button, and the air volume will automatically adjust to maximum while turning on the external circulation. Using the air conditioner to defog is a simple and quick method, but it is mainly used when fogging occurs while driving. If you want to prevent fogging in advance, it is recommended to use an anti-fog spray for better results.
I often encounter the problem of fogging on the car windows, especially when driving in rainy or snowy weather. Fogging is mainly caused by the large temperature difference between the inside and outside of the car and high humidity, with exhaled air condensing on the glass. The solution is to use the defogging mode button of the air conditioner, which has a fan-shaped icon on the center console; after turning it on, set the air direction to the windshield, increase the fan speed, and use the air conditioner (cold or hot air) to dehumidify. At the same time, open the window slightly to assist ventilation. If the air conditioner is slow to take effect, use a tissue or towel to quickly wipe it dry as a temporary emergency measure, but don't wipe while driving as it is dangerous. Regularly cleaning the glass to reduce stains that absorb moisture and placing moisture-absorbing packets on the dashboard can also prevent fogging. If the air filter is dirty, replace it to ensure dehumidification efficiency. These habits have helped me significantly reduce the frequency of fogging.
