Where is the defogger switch for sedans?

The defogger switch is located on the center console, marked with a fan-shaped airflow icon featuring a front windshield and three upward-waving lines. In rainy weather when window fogging occurs, you can handle it through the following methods: 1. Air conditioning defogging. This method is the most convenient and quick. 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. The fog on the glass will dissipate shortly. 2. Open windows for air convection. Opening windows increases air circulation, reducing the temperature difference inside and outside the car, thereby weakening the conditions for fog formation. 3. Use a defogging spray. Simply spray it evenly on the glass surface and wipe it clean with a dry towel. Its principle is to utilize the properties of surfactants, forming a protective film on the glass surface after staying for a while, altering the surface tension of water molecules, causing fog droplets to coalesce into larger droplets, thus preventing them from obstructing vision.
I've been driving for over a decade, and the defogger switch is usually located on the center console near the air conditioning system. Look for an icon with a fan and wavy lines—that's specifically for clearing the front windshield fog. The position varies slightly by brand: Japanese cars may place it in the button area to the left of the steering wheel, while European and American designs often position it next to the central knobs. When fog appears, press the switch immediately, set the fan speed high with warm air to quickly clear the fog and prevent blurred vision. The rear window defogger has a dedicated button too, marked by a rectangle with wavy lines representing the heating element. Never use cold air to defog—temperature differences can worsen condensation. In rainy or cold seasons, activate it preemptively. If fog suddenly forms while driving, pull over first before operating. Safety comes first—beginners should study the manual to memorize the locations. Clean the buttons regularly to prevent dust buildup that could affect responsiveness. Driving in foggy conditions is high-risk, making the defogger switch a lifesaver.
