How to Turn on Defogging in Summer?
2 Answers
First, adjust the air direction switch to the defogging position, activate the external circulation to let fresh air blow in, and set the compressor and fan speed to the highest to speed up defogging. If the side window defogging is not fast enough, it is best to close the two central air vents to allow the airflow from the side vents to quickly disperse the fog.
When it comes to defogging in summer, I have a lot of experience during long-distance driving. Fogging on the windows is caused by the temperature difference between the inside and outside of the car or high humidity on rainy days. As soon as I notice fog, I immediately press the defog button, usually marked with a fan-shaped symbol and wavy lines. At this point, the air conditioning automatically turns on the AC for cooling and dehumidifying, with the fan speed set to maximum to blow on the front windshield, and it clears up in seconds. Remember to turn on the external air circulation on rainy days, otherwise the humidity inside the car will only get worse. Don’t forget the rear window defroster button either—it uses electric heating wires to clear fog, so don’t confuse it with the front window. Once visibility is clear, adjust the fan speed back to normal, as keeping it on high is not only uncomfortable but also wastes fuel. Once during a heavy rain, I forgot to turn on the external air circulation, and the fog kept getting worse—that was a real lesson learned.
