Which switch is used for defogging in the car?

[LaWyatt]

The defogging switch symbol in a car is: a fan shape with three upward wavy lines inside. Methods for defogging inside the car: The quickest way to defog the car interior on rainy days is to turn on the front windshield defogging mode, then activate the air conditioning cooling (A/C) switch, and set the temperature to the lowest. The fog will clear up quickly. For automatic air conditioning systems, simply press the one-touch defrost button, and the remaining operations will be performed automatically. Other defogging methods: To prevent fogging in advance, it's advisable to prepare a defogging spray. The principle of defogging spray is to create a protective film on the glass surface, causing tiny fog droplets to merge into larger water droplets that won't obstruct vision. To use, spray the defogging agent on the inner surface of the window and wipe it clean with a tissue or towel.
