How to Use Air Conditioning to Defog Car Windows on Rainy Days?

[VonPaisley]

Methods to defog car windows using air conditioning on rainy days: 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 for defogging car windows on rainy days: Open windows: Open two windows diagonally opposite each other in the car to help remove fog. Use defogging spray: Apply a defogging spray to prevent water vapor from condensing on the glass; one application can prevent fogging for about ten days.
