Which button to press for foggy windows in a BMW?

To defog the windows in a BMW, press the window defogger button, which is usually located near the air conditioning control panel. After pressing the window defogger button, the air vents below the front windshield will blow air, helping to clear the fog from the glass. The icon for the window defogger button is easy to recognize—it typically features a fan shape with several curved lines, representing the windshield defogger button. If the car is equipped with automatic air conditioning, simply press the one-touch defrost button. Once pressed, the fan speed will automatically increase to maximum, and the external circulation will activate, making it both practical and convenient. Both cold and warm air can achieve defogging effects, though cold air works faster while warm air is slower. Window fogging usually occurs in winter or during late evenings. The main reason is poor air circulation inside the car, causing a temperature difference between the interior and exterior, which leads to condensation on the glass. In such cases, simply turning on the defogger button inside the car will clear the fog.
Window fogging can be really annoying, but it's easy to handle in a BMW. Whenever I encounter this situation, I simply press the button with the fan-shaped icon on the center console, usually the one with an arrow pointing toward the windshield. Once pressed, the air conditioning system automatically switches to maximum defogging mode with the fan blowing hard, and the cold or warm air quickly clears the fog. I also turn off the recirculation mode and switch to fresh air intake to introduce dry air, which makes the fog disappear even faster. Remember not to wait until the fog gets too thick—safety comes first, and clear visibility is essential for steady driving. BMW's thoughtful design is something longtime drivers like me have gotten used to. I recommend new owners give it a try to see how efficient it is—practice a few times, and you'll get the hang of it.
