On rainy days, press the front window defogging button and turn on the air conditioning cooling switch, then set the temperature to the lowest. The fog will clear quickly. For automatic air conditioning, simply press the one-touch defogging button, and the remaining operations will be performed automatically. Some models are equipped with rear window electric heating and external rearview mirrors. Just click the switch, and the fog will disappear in about a minute. For automatic air conditioning, usually pressing the one-touch defrost button will automatically turn the fan to maximum and activate the external circulation, which is both practical and convenient. You can also use the heating system to defog. If the car has just started, do not turn on the air conditioning immediately. Wait a few minutes for the engine to warm up and the water temperature to rise, then start the heating, set the fan to maximum, and turn on the front window defogging mode. The fog will disappear in a few minutes. This method also works for fog on the outside of the glass in summer.
I've been driving for over ten years, and fogging up inside the car on rainy days is a common occurrence. I immediately locate the fan-shaped icon button on the center console near the steering wheel and press it—this is the front windshield defogger function button. Generally, this button automatically activates the air conditioning fan to blow dry air forcefully onto the glass for quick defogging. The main reason for fogging is the low outside temperature during rain, combined with the humid warm air inside the car, causing water droplets to condense and obstruct visibility. Therefore, timely action is crucial. After pressing the button, wait a few seconds for it to take effect. If there's no change, you can press the fan button again to increase the airflow or switch to external circulation to introduce dry air—avoid using internal circulation as it can worsen humidity. Remember, safety comes first. If the fogging is severe, pull over and wait until visibility is clear before driving again. Never panic or operate hastily to prevent accidents.
As a new driver who just got my license, I was completely confused when the car fogged up during heavy rain. Later, I learned from experienced drivers that I should press the fan-shaped button on the air conditioning panel—pressing it can quickly defog the windshield. This button is usually located near the air conditioning controls. Fogging occurs due to temperature differences and humidity. After pressing the button, the air conditioning will automatically blow air to remove moisture. If the effect is slow, try lowering the temperature or briefly opening the window for ventilation. The operation is simple and doesn’t require professional knowledge. As a beginner, don’t panic—take your time to familiarize yourself with the car’s control buttons and read the user manual to prepare for next time. For safety, if visibility becomes blurry, slow down immediately and focus on handling the situation—avoid distracted driving.
