Which button is for defogging the car windows?

Car defogger button: Located near the air conditioning control buttons. If it is the front windshield defogging button, the icon is a fan shape; if it is the rear windshield defogging button, the icon is a square. Some cars have both front and rear windshield defogging buttons on the same button. Below is related information about car defogging: 1. The car defogger switch controls the car defogger, which is used to reduce moisture, fog, and frost on the front and rear windshields and the exterior rearview mirrors to improve visibility. Press the defogger switch, and the indicator light will turn on. The defogger works for about 15 minutes, after which it will automatically turn off. To manually turn off the defogger, press the defogger switch again. 2. Press the front windshield defroster switch, and the front windshield defroster starts working; press the rear windshield defroster switch, and the rear windshield defroster starts working.
I often encounter this situation when I first started driving - the windshield suddenly gets fogged up, leaving me flustered. That button to defog the glass is usually the windshield defroster button on the air conditioning control panel, with an icon resembling a fan or a rectangle with arrows. During my first long-distance drive when I wasn't familiar with it, the fog almost caused me to crash. A friend told me to simply press that button, and the AC would automatically direct airflow to the windshield to quickly remove moisture. Now I understand that fogging occurs due to significant temperature differences between inside and outside the car or high humidity from breathing. Using this button provides a quick solution. Normally, I prevent fogging by first turning on the air recirculation mode or raising the interior temperature to reduce condensation. If the fog is too thick and the button works slowly, I just wait a minute or two for the system to do its job. This makes driving much safer, especially during rainy days or winter nights when extra caution is needed.
As an average car owner who drives frequently, I've encountered many instances of windshield fogging. The button to remove fog is located on the windshield defroster button in the air conditioning area of the center console, usually marked with a fan-shaped icon. A light press activates the hot air defogging function. I remember once driving on the highway during heavy rain when fog obscured my vision, making it hard to see the road. I quickly pressed that button, which immediately alleviated the danger. Fogging occurs due to temperature differences between the inside and outside or excessive humidity. Pressing the button directs the air conditioning to focus on blowing air and dehumidifying. I've also found that sometimes turning on the internal circulation first and then switching to external circulation is more effective, or simply adjusting the temperature knob to complement it. The button's position might vary slightly between new and old cars, but it's generally near the air conditioning panel. For safety, I recommend checking the button's responsiveness every time you start the car. Developing this habit can prevent major troubles.
From my driving experience, the commonly used button to defog the windshield is the windshield defrost button, prominently located on the air conditioning panel. Pressing it activates the fan to blow hot air, quickly removing fog. This method works well because fog forms due to temperature and humidity changes, and the air conditioning's dehumidification mechanism helps balance the cabin environment. When operating, simply press the button without additional settings—some cars even automatically adjust the airflow. If the button doesn't respond, it might be a fuse issue. In such cases, try opening the windows for temporary defogging, but address the underlying problem promptly during long trips.
