Which Air Circulation Mode to Use for Defogging the Car in Snowy Weather?

In snowy weather when the car interior fogs up, turn on the external air circulation mode to introduce outside air into the car, which can remove the fog more quickly. You can also defog by opening the windows slightly for ventilation: Crack the windows open just a little—about the width of a thumb—to allow air circulation and reduce the temperature difference between the inside and outside of the car. Lowering the interior temperature helps achieve the defogging effect. Another method is to use the car's air conditioning for defogging: To defog in snowy weather, turn on the AC and set it to windshield mode for quick defogging. In winter, press the front windshield defogging button on the automatic climate control panel, and the air conditioning will automatically adjust to a higher temperature with maximum fan speed to clear the fog.

In snowy weather, the car interior tends to fog up easily. I always switch the circulation mode to outside air circulation. The outside air circulation draws in cold air from outside, which quickly removes moisture from the windows, making the fog dissipate. When I'm driving and notice fog forming, I immediately press the outside air circulation button and turn on the warm air from the air conditioner to blow on the front window—it works effectively. Avoid using recirculation mode, as it causes moisture to accumulate inside the car, leading to faster and heavier fogging. By the way, in winter, remember to regularly check and clean the cabin air filter. Keeping it clean can significantly reduce fogging issues, preventing distractions and ensuring driving safety.

Fogging up on snowy days is quite annoying. I recommend turning on the external circulation mode. External circulation draws air from outside the vehicle, helping to dry the interior and dissipate fog faster. Use it together with the warm air from the AC, just press the defogging button. Avoid using internal circulation, as it only traps moisture inside and worsens fogging. Additionally, keep your windows clean and free of excessive dirt to prevent fogging. Regular maintenance of the AC system is also important to avoid sudden malfunctions.

If fog forms on a snowy day, I immediately switch to the external air circulation mode. Introducing dry, cold air from outside the vehicle effectively clears the fog. Simultaneously, turn on the air conditioning with warm air directed at the front windshield to quickly restore visibility. Remember not to use the internal circulation mode, as it traps moisture inside, making the fog worse. Keep it simple for safe driving.
