What is the symbol for blowing air on the windshield inside the car?

The symbols for blowing air on the windshield inside the car are: 1. A fan-shaped symbol indicates defrosting for the front windshield; 2. A rectangular symbol indicates defrosting for the rear windshield. How to deal with fogged windshields: 1. Cold air defogging: Locate the front window defogging switch, set the fan speed to high, turn on the AC switch, and adjust the temperature to low; 2. Warm air defogging: Turn on the heater, set the fan speed to high, and the fog will disappear in a few minutes; 3. Anti-fog spray: Simply spray it evenly on the glass surface and wipe it clean with a dry towel. The principle of anti-fog spray is to use surfactants to form a protective film on the glass surface, altering the surface tension of water molecules, causing fog droplets to coalesce into larger droplets, thus not obstructing visibility.
Speaking of the symbol for blowing air onto the windshield inside a car, it's actually the defrost or defog button icon on the air conditioning panel. It typically depicts a rectangle representing the front windshield with wavy lines or arrows indicating airflow directed toward it. With over 20 years of driving experience, I find this feature particularly useful during rainy or snowy weather when the windows fog up and obscure visibility. Simply turn the AC knob to this symbol, and hot air blows directly onto the glass to quickly clear the fog. Some premium cars even have an auto-activation feature that engages when high humidity is detected. As a seasoned driver, I advise beginners to master this function early as it helps prevent accidents. Remember to check if the cabin air filter is clogged if the effect is poor, as this ensures sufficient airflow. Develop the habit of turning off the heating before parking to avoid potential windshield damage.
