Which Button to Press for Defogging on Rainy Days?
3 Answers
Here are the methods for defogging on rainy days: 1. For manual air conditioning, turn on the front window defogging mode, set the fan speed to maximum, turn on the A/C switch, and then adjust the temperature to the lowest. The fog on the glass will disappear. 2. Some models are equipped with rear window electric heating and external rearview mirrors. Simply press the switch to activate, and the fog will be cleared in about a minute. 3. For automatic air conditioning, usually just press the one-touch defrost button. After pressing it, the fan speed will automatically increase to maximum and the external circulation will be activated, which is both practical and convenient. 4. In winter, turning on the A/C can make it too cold. You can also use the heating system for defogging. If the car has just started, temporarily avoid turning on the air conditioning. Wait for the engine to warm up for a few minutes until the water temperature rises, then start the heating. Set the fan speed to maximum and activate the front window defogging mode. The fog will disappear in a few minutes.
I've got plenty of experience with this! I used to struggle with foggy windows when driving in the rain, and it took me a long time to figure it out. Generally, the button with the window icon and wavy lines is the front defroster. In Volkswagen cars, it's a fan shape with an arrow, while Toyota uses a square glass with airflow patterns. Remember to turn on the AC compressor (the little snowflake icon) for it to work effectively. Setting the temperature slightly lower than the outside temperature clears the fog the fastest. Back in the day, I used to just turn on the heater, but that only made the fog worse, to the point where I couldn't even see the rearview mirror. Now I know to also switch to external air circulation to keep the cabin from getting too humid. Oh, and the rear window defroster is the rectangular icon with heat waves—it usually takes about two or three minutes to work after pressing it.
Don't panic when your windshield fogs up on rainy days—I've got a simple procedure to share: First, press the defog button marked 'FRONT' or with a fan-shaped arrow on the AC panel, then turn on the A/C switch to force dehumidification. Next, crank the fan to maximum and briefly open the windows for ventilation. Set the temperature around 22°C—not too high. If the rear window also fogs up, hit the rectangular button with wavy lines for heating. The key is to act preemptively; waiting until it's fully fogged up slows the process. Last time during a heavy downpour, I tried running the defogger on the highway, and visibility cleared up within five minutes. Remember, never wipe by hand—it’ll just smear worse!
