Quick answer

To use your car's defogger, activate the defrost button, set the fan to high, turn on the A/C, and disable air recirculation to clear moisture from the glass.

To clear a foggy windshield, press the front defrost/defog button, which is typically marked with a windshield icon. Set your fan to high and the temperature to warm or hot to help evaporate moisture. Crucially, turn off the air recirculation setting to pull in drier outside air, and ensure the air conditioning (A/C) is on to act as a dehumidifier. For the rear window, press the separate rear defogger button, often marked with a rectangle and squiggly lines, which activates heating elements in the glass. This button may also activate heated side mirrors in some vehicles. Once visibility is restored, you can adjust the settings to your preference.

Answer details

1

Front Windshield Defogging

Press the front defrost button (often a windshield icon) and set the temperature to warm or hot with the fan on high to evaporate moisture from the windshield.

2

Manage Air Recirculation

Turn off the air recirculation button to allow fresh, drier outside air into the cabin, which prevents moisture from building up on the glass.

3

Use Air Conditioning

Keep the A/C turned on while defogging, as it acts as a dehumidifier to remove excess moisture from the air inside the vehicle.

4

Rear Window Defogging

Press the rear defogger button (usually a rectangle with squiggly lines) to activate heating elements in the rear window and often the side mirrors.
