How to Turn on the Air Conditioning When the Car Windows Fog Up on Rainy Days?

Methods to defog car windows on rainy days by using air conditioning: Turn on the external air circulation to introduce outside air into the car, which can remove fog more quickly. Direct the air conditioning airflow to the front windshield to defog it, thereby reducing the temperature difference on both sides of the glass. When the rear window fogs up, use the rear window heating function to evaporate the fog. Solutions to defog car windows on rainy days: 1. Open the windows: Open two diagonally opposite windows in the car to help remove fog. 2. Use anti-fog spray: Apply anti-fog spray to prevent water vapor from condensing on the glass. One application can prevent fogging for about ten days.
When fogging occurs inside the car on rainy days, I always start the vehicle immediately and press the AUTO button on the center console. The air conditioning system will automatically adjust the airflow and temperature to defog. I turn the temperature knob to around 20 degrees on the windshield setting, and the system intelligently distributes cool air to reduce glass humidity. At this time, using the external circulation mode is crucial as it draws dry air from outside to minimize fog accumulation. If the fogging is severe, I may manually increase the fan speed or set the air direction towards the windshield to quickly blow away water droplets. The entire process is simple and efficient, though I'm reminded to first ensure pulling over safely before operating to avoid distracting from driving. Regularly cleaning interior window stains after rain also helps prevent fogging, ensuring clear visibility for safer driving.
