What to Do When the Car Windows Keep Fogging Up with Air Conditioning On in Rainy Days?
2 Answers
In summer, use air conditioning for cooling and defogging. Turn on the A/C switch, set the temperature to the lowest, and direct the air conditioning vents to blow cold air onto the front windshield. In winter, use warm air for defogging. If the car has just started, wait a few minutes for the engine to warm up, then use the warm air to blow onto the front windshield. Adjust the side window vents so that they do not blow directly onto the side window glass.
Driving with foggy windows on rainy days can be quite annoying, and I've encountered this issue frequently before. The most straightforward solution is to use the air conditioning defogging function. Locate the windshield vent button on the control panel, press it, turn on the AC switch and ventilation mode, which will automatically dehumidify. The fogging occurs due to high humidity inside the car and cold temperatures outside, causing moisture to condense on the glass. Using the external air circulation to let fresh air in helps prevent moisture buildup. Regularly keeping the glass clean by wiping it with a clean cloth or applying anti-fog spray can prevent this issue. Safety comes first—if fog suddenly appears while driving, slow down and pull over to handle it carefully to avoid accidents. I've also found that slightly opening the window for a few seconds to ventilate works quite effectively.
