Which switch is used to defog car windows?

[DamianAnn]

To defog car windows, simply turn on the switch located in the center of the dashboard. Methods for defogging include: 1. For light fog, open the windows to reduce the temperature difference between inside and outside the car, which will disperse the fog; 2. Turn on the heating before driving; 3. Turn on the car's air conditioning; 4. Activate the car's defogging function; 5. Apply a mixture of dish soap and water or soapy water as an anti-fog agent on the windows; 6. Place a dehumidifier box, like those used in wardrobes, inside the car. The reasons for foggy car windows are: 1. When humidity is high, the window temperature is lower than the dew point temperature; 2. Damp car floor mats; 3. Large temperature difference between the inside and outside of the car; 4. There is a certain temperature difference between the two sides of the window.
