How to Properly Use the Car Air Conditioner on Rainy Days?

First, turn on the cooling mode of the air conditioner and then switch on the AC. Only when the AC is turned on will the air conditioning cooling system start operating. Direct the airflow towards the windshield, and the fog will gradually dissipate. Only when visibility is completely clear should you drive on the road; do not take any chances.
On rainy days, preventing window fogging is key when using the air conditioning. I usually start by turning on the fan first after getting in the car, selecting the external circulation mode to let fresh air in and reduce interior humidity. Then I turn on the AC, setting the temperature to around 22°C, and adjust the airflow direction to blow at the windshield to clear fog. Avoid switching to internal circulation immediately, as that will increase cabin humidity and make fogging more likely. If the car has automatic climate control, press the AUTO button to let the system optimize airflow and temperature settings automatically, saving time and effort. Maintain stable AC operation while driving to avoid temperature fluctuations that could affect visibility. Also, check if the cabin air filter is clean – humid weather makes it easier for dust to accumulate, which can impact defogging effectiveness. This approach ensures both safety and comfort, keeping your view clear during rainy drives.
On rainy days, the way I use the car's air conditioning focuses most on preventing window fogging. First, turn on the fan using the external circulation mode to minimize moisture intake. Then, activate the air conditioning, setting the temperature to around 22 degrees, and direct the vents toward the windshield to clear the fog. Don’t forget to switch to the dehumidification mode; if the car doesn’t have one, simply select the cold air setting. Occasionally, I manually adjust the fan speed to a medium level for balanced effectiveness. After starting, I don’t rush to switch to internal circulation—wait until some moisture is expelled before changing over. This ensures better visibility while driving and reduces noise for a quieter ride. Remember to close the windows tightly to keep rainwater out and improve fuel efficiency. The whole process is straightforward and easy to manage, taking just seconds to set up for a worry-free drive.
To deal with foggy windows on rainy days, I prioritize ensuring the air conditioner quickly dehumidifies. After starting the car, press the AUTO button (if available) to let the system adjust automatically; set the temperature between 21-24°C with moderate fan speed, directing airflow toward the windshield. Choose the external air circulation mode to bring in fresh air and expel moisture—the fog should clear within minutes, then switch to internal circulation to maintain comfort. Cleaning the air filter can improve efficiency, and it's especially important to prevent bacterial odors in high humidity during rainy days. Drive smoothly and adjust the temperature steadily to avoid sudden changes that could affect safety.
