Which button is for defogging the Volkswagen windows?
2 Answers
Volkswagen windows have two buttons for defogging: front windshield defogger and rear window heating. Front Windshield Defogger: The front windshield defogger works by directing the air conditioning airflow to the front windshield, reducing the temperature difference on both sides of the glass to achieve defogging. Rear Window Heating: When the rear window fogs up, the rear window heating function can evaporate the moisture, achieving defogging. (Note: The rear window heating function is usually combined with the exterior rearview mirror heating function.) Air Conditioning Defogging: Turn on the front windshield defogging mode, then activate the air conditioning cooling (A/C) switch, set the temperature to the lowest, and the fog will clear quickly. For automatic air conditioning, simply press the one-touch defrost button, and the remaining operations will proceed automatically.
With twenty years of experience driving Volkswagen cars, I've encountered window fogging all too often. On a Volkswagen, the defogger button is located on the air conditioning control panel. For the front windshield, press the fan-shaped button with wavy lines, which activates the fan to blow hot air and remove moisture. For the rear window, use the rectangular button for heating. I often face fogging on rainy days or cold winter mornings when starting the car—don't panic; just press the defogger button and let the fan run for a few minutes to clear it up. To prevent fogging, set the air conditioning to windshield mode during regular use, and keep doors and windows closed to block humid air. Also, a dirty cabin air filter slows down defogging, so replace it regularly. Clear visibility is crucial for safe driving—just press the right buttons instead of wiping haphazardly with a cloth.
