Which button to press for defogging car windows?

To defog car windows, press the windshield defogger button, which is usually located near the air conditioning control panel. After pressing the windshield defogger button, the air vents below the front windshield will blow air, effectively clearing the fog. The windshield defogger button is easily recognizable by its icon, typically a fan shape with several curved lines, representing the windshield defogging function. If the car is equipped with automatic air conditioning, simply pressing the one-touch defrost button will automatically turn the fan to maximum speed and switch to external air circulation, making it both practical and convenient. Both cold and warm air can achieve defogging effects, though cold air works faster while warm air is slower.
Speaking of window fogging, I have quite a bit of experience. It's really annoying when this happens while driving on the road. Fogging mainly occurs due to the large temperature difference between the inside and outside of the car, causing moisture to condense on the glass and obstruct visibility, which is quite dangerous. I recommend you directly find the button with the fan-shaped symbol, usually the front windshield defogging button, which looks like a fan. Press it, and the air conditioning will automatically increase the airflow, blowing cold air to remove moisture. In winter, the air might be a bit colder, but it works quickly. You can also use the external circulation button to let fresh air in and reduce fog accumulation. Avoid using internal circulation as it increases humidity and makes the fog worse. For cars with automatic air conditioning, just press the AUTO button and set the temperature. Remember to check if the air filter is clean before driving to prevent fogging. Safety first—drive slower when there's fog, and avoid slamming on the brakes to prevent accidents.
