Which Button is the Defogger Switch for Sedans?

The defogger switch is located on the center console panel, marked with an icon of the front windshield and three upward-curving lines, resembling a fan-shaped airflow symbol. Below are methods for handling car defogging: 1. Use the air conditioning to defog. 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. 2. If the car has just been started, avoid turning on the air conditioning immediately. Wait for the engine to warm up for a few minutes until the water temperature rises, then start heating. Set the fan speed to maximum and activate the front window defogging mode. 3. Open windows to allow air convection, which increases airflow and reduces the temperature difference between the inside and outside of the car, thereby weakening the conditions for fog formation. 4. Use a defogging spray. Simply spray it evenly on the glass surface and wipe it clean with a dry towel. Its principle involves using surfactants to form a protective film on the glass surface, altering the surface tension of water molecules, causing fog droplets to coalesce into larger droplets that do not obstruct vision.
