Which button is for defrosting the windshield in a BMW?
1 Answers
The button for defrosting the windshield in a BMW is located on the center console and resembles a fan and a rectangle. Symbols for defrosting: The fan-shaped button with three upward wavy lines inside is for defrosting and demisting the front windshield, also known as the front defroster. Pressing this button directs the air conditioning airflow to the front windshield. The rectangular button with three upward wavy lines inside is for defrosting and demisting the rear windshield, also known as the rear defroster. Most rear windshields equipped with heating wires have this function. Pressing this button activates the heating wires inside to remove fog and moisture from the glass. Methods for defrosting the car windshield: The fastest and most effective method is to turn on the air conditioning cooling function and the external circulation, using the maximum airflow, which usually takes only about ten seconds to solve the problem. The most fundamental solution is to use the air conditioning's hot air to blow on the windshield. The principle is to use warm air to dry the water vapor molecules in front of the windshield and circulate them outside the car to prevent them from condensing on the glass and forming water droplets. The downside is that the defrosting effect is relatively slow.
