The defogging button symbol in a car is a fan shape with three upward wavy lines inside. Here are specific methods for defogging inside the car: 1. Proper use of the air conditioning system: Park the car, start the air conditioning, turn the temperature adjustment button to the warm air direction, press the defogging button, and use the warm air from the air conditioning to dry the windshield fog. When defogging, you can switch the air conditioning to external circulation to allow fresh outside air to enter the cabin. Setting the compressor and fan speed to 25°C or higher can speed up the defogging process. 2. Use specialized anti-fog products: Before each use, spray evenly on the windows and wipe clean, forming a transparent protective film on the glass to prevent fog formation. One application can prevent fog for about ten days to half a month. 3. Cold and hot air convection: If the fog is not heavy, you can open a crack in the windows on both sides to allow air convection inside the car. The temperature inside the car will gradually approach the outside temperature, and the fog will dissipate.
I hate it when the car fogs up, especially on rainy winter days. In this case, you need to press the windshield defogger button, the one with a fan icon and three wavy lines in the middle, which can be found on the central air conditioning panel. After 15 years of driving, I've learned that when using this button, you should also turn on the AC switch to activate the compressor for faster dehumidification. For manual air conditioning, adjust the temperature to the cold air setting, while for automatic air conditioning, simply pressing AUTO is the most hassle-free. Remember to use the external circulation mode to let fresh air in, as it defogs much faster than internal circulation. When defogging, it's best to set the fan speed to maximum and not turn it off immediately—keep it blowing for two or three minutes to ensure the glass dries completely. If the rear windshield fogs up, press the nearby square icon with wavy lines, which activates the heating wires. To prevent fogging, you can blow hot air on the glass for five minutes before setting off or buy an anti-fog spray and apply it once a month for good results.
