Which key fogs the BMW windshield?

1. If the front windshield is foggy, you can press the defogging button of the front windshield in the air conditioning control area.

2. If the rear windshield is foggy, you can press the rear windshield heating button in the air conditioning control area.

3. If you find that the fog inside the car is not big, you can open the windows on both sides, so that the air inside and outside the car will form convection, the temperature difference will decrease, and the fog will slowly disappear.

The principle of this method is the same as turning on the air conditioner to cool down.

5. The disadvantage of convection through the window is very obvious, which is not available in rainy and snowy weather, expressway and foggy days.
