What to Do When the Outside of the Windshield Fogs Up While Driving at Night?

[Jasper]

The solutions for dealing with fog on the outside of the windshield while driving at night are as follows: 1. Lower the windows: Slightly lower the windows to create a gap, reducing the temperature difference between the inside and outside of the car, which will help the fog disappear. In summer, fog forms on the outside of the car glass because the temperature inside the car is lower than outside. When the hot outside air meets the cold glass, the water vapor in the outside air condenses into small droplets. 2. Turn on the air conditioning: Use the recirculation mode and adjust the air vents to blow onto the windshield to quickly clear the fog. 3. Turn on the heater: Set the control to the warm air position, increase the fan speed, and also adjust the air vents to blow onto the windshield. This will raise the temperature inside the car and dry the air.
