Steps
Start the engine and let it idle so the AC and blower have power. Do this before you set off, not while driving with a fogged view.
Find the front defogger button. It is usually a rectangle with three wavy arrows pointing up, sometimes marked FRONT.
Switch the AC on. The air conditioning dries the air inside the cabin, which is what actually removes the moisture from the glass.
Set the airflow so it comes out of the vents at the base of the windshield, not the face or foot vents.
Turn the fan to a medium or high speed and set the temperature to a mild warm setting. Hot air clears fog faster but can feel uncomfortable.
Switch the air intake to fresh air from outside. Recirculate mode traps the damp air inside and slows clearing.
Leave the defogger running until the glass is completely clear, then lower the fan speed and keep the AC on to stop fog coming back.
If the glass is wet on the outside from rain or spray, run the wipers instead. Wipers handle water on the surface, the defogger handles fog on the inside.
Tips and common mistakes
Fog forms when warm, moist air inside the car meets cold glass, so drying the air with AC fixes the cause rather than the symptom.
Do not wipe the inside of the windshield with your hand or a sleeve. It leaves smears that catch light and fog up faster next time.
Clean the inside of the glass with glass cleaner every few weeks. A dirty film holds moisture and makes fogging worse.
Keep the AC running on rainy drives even when it feels cool, because it keeps the cabin air dry and the glass clear.
Questions
Why does my windshield fog up so much in the monsoon?
Rain and wet clothes bring a lot of moisture into the car, and the glass cools faster than the air inside. When that damp air touches the cold glass, it condenses into fog.
Should I use hot or cold air from the defogger?
Warm air clears fog faster because it holds more moisture, but cold dried air from the AC also works and feels better in humid weather. Either way, keep the AC on.
Why does the defogger not clear the outside of the glass?
The defogger works on fog inside the cabin. Water on the outside is rain or spray, so use your wipers and washer fluid for that.
