What is the icon for the defroster switch?

[McLucas]

The defroster switch is an icon of the front windshield with three upward-waving lines. Below are several methods for defogging a car: 1. Wipe off the fog with a towel: This is the quickest defogging method, but you must first stop the car. Wiping fog while driving can distract you and affect driving safety. 2. Use window ventilation to defog: Since window fogging is caused by the temperature difference between the inside and outside of the car, you can open the window slightly. The incoming air while driving will lower the interior temperature, and the fog will naturally dissipate. 3. Use the air conditioning defogging function: Most cars are equipped with a defogging function; simply turn on the window defogging feature. 4. Apply anti-fog spray in advance for prevention: This is especially useful in cities with large day-night temperature differences or frequent rain and snow. You can also make your own defogging solution—applying everyday household items like soap or dishwashing liquid to the windows can help reduce fogging.
