Which Button is the Defogger in a Car?

[VonAmir]

There are two defogger buttons in a car. One is for the front windshield defogger, marked with a fan shape containing three upward wavy lines. The other is for the rear windshield defogger, marked with a rectangle containing three upward wavy lines. When encountering foggy windows on rainy days, you can handle it through the following methods: 1. Air Conditioning Defogging: Locate the front window defogger switch, set the fan speed to maximum, turn on the A/C switch, and adjust the temperature to the lowest setting. The fog on the glass will disappear shortly. 2. Open Windows for Airflow: Opening the windows increases air convection, reduces the temperature difference inside and outside the car, and weakens the conditions for fog formation. 4. Prepare a Defogging Spray: Simply spray it evenly on the glass surface and wipe it clean with a dry towel.
