How to Turn on the Car Air Conditioning on Rainy Days?
2 Answers
Rainy days are prone to fogging. Turning on the external circulation to draw outside air into the car can remove fog more quickly. Directing the air conditioning airflow to the front windshield helps defog it by reducing the temperature difference on both sides of the glass. When the rear windshield fogs up, the rear window heating function can be used to evaporate the moisture. Precautions for driving in the rain are as follows: 1. Slow down: Regardless of road width or condition, drive slowly in the rain, always pay attention to the distance between your car and others, and be prepared to take emergency measures. 2. Maintain distance: Visibility is reduced in the rain, so keep a safe distance from other vehicles, especially large trucks, which can block your view and may splash water, making driving more difficult for smaller cars.
On rainy days when using the air conditioning, as a frequent driver, I usually start the car and immediately turn on the AC system. Press the fan button, set it to the highest speed, and adjust the airflow direction to blow toward the windshield for quick defogging. Remember to check that the A/C indicator light is on—this dehumidification function is crucial. Set the temperature to around 20°C, not too low, to avoid feeling cold. Turn on the external circulation mode for a while to let fresh air in and reduce humidity, then switch to internal circulation for warmth once the fog clears. Rainy days are dimly lit, and fogged-up windows can severely impact safety—I’ve learned this the hard way when I forgot to defog and nearly had an accident. So, make it a habit to check if the AC buttons are working before driving. If the car has an automatic AC function, pressing the AUTO button makes things much easier. Throughout the process, prioritize driving safety—ensure the fog is completely cleared before hitting the road, and don’t rush.
