The defogging button in a is located on the air conditioning control panel below the CD player. It is marked with a fan-shaped symbol containing three curved upward arrows. The reasons for car window fogging are as follows: Temperature difference between inside and outside the car: Due to the temperature difference between the inside and outside of the car, the window glass, which is in contact with the outside, is cooler. The water vapor inside the car condenses on the glass, forming fog. When the window temperature is below the dew point and the air humidity is constant, condensation easily forms on the window surface, leading to the common fogging phenomenon on the windshield. Temperature difference between the two sides of the window: There is a certain temperature difference between the two sides of the window. If the temperatures on both sides of the window are different, the surface with the lower temperature has a lower saturated vapor pressure than the surrounding environment. This causes water vapor to gather on the glass surface, forming tiny water droplets that appear as fog. It is essential to remove window fog promptly, as it can significantly affect the driver's visibility and safety.
