How to Turn on Defogging on Rainy Days?
2 Answers
First press the A/C switch button, then turn on the front windshield defogging button, set the temperature to the lowest, and adjust the air volume to eliminate fogging. When the car is just started, do not turn on the air conditioning immediately. After the water temperature rises, start heating, turn the air volume to the maximum, and press the defogging button to make the fog disappear.
Driving in rainy weather with a foggy windshield is particularly annoying and affects safety. Having driven for over 10 years, I deal with this situation immediately: After starting the car, first press the defrost button on the dashboard—it looks like a small fan or is labeled 'DEF'. Then, turning on the air conditioning compressor is crucial; even if it's cold outside, it helps quickly remove moisture. Not using it may cause the fog to reappear. Switch to the external air circulation mode to let dry outside air in; internal circulation can accumulate moisture from breathing. Set the fan speed to medium or high, and adjust the temperature to a comfortably warm level, around 20 degrees Celsius is ideal. Don’t forget to turn on the rear window heating button to prevent fogging at the back. Since humidity is high on rainy days, I recommend keeping a dry cloth in the car to wipe the windows as needed. Additionally, regular maintenance of the air conditioning system, such as replacing the air filter to prevent blockages, can reduce fogging. These small details ensure clear visibility and make driving safer.
