What are the methods to defog the car interior during summer rainy days?
2 Answers
Turn on the defogging function by activating the car's air conditioning and selecting the defogging mode for quick fog removal. During rainy weather, fogging is usually caused by the temperature difference between the inside and outside of the car. You can adjust the air conditioning to a lower temperature to keep the indoor and outdoor temperatures similar, achieving the defogging effect. Without lowering the interior temperature, you can choose the windshield and foot vent modes to continuously prevent fogging in the cabin.
It's so annoying when the car fogs up during summer rains. My most common method is to immediately turn on the AC cold air, set it to the lowest temperature, and increase the fan speed. At the same time, press the windshield defogging button and select the upward airflow direction to blow on the windshield and side windows. Remember to turn on the external circulation mode, which allows dry outside air to enter the car. The fog will dissipate once the humidity decreases. If the rain is too heavy, you can slightly open a window to balance the temperature difference inside and outside. When parking, I usually wipe the inside of the glass with a clean, soft cloth in advance. Prevention is actually more important—ensuring the window seals are intact and the AC filter is clean before setting off can improve dehumidification efficiency.
