Why Can't the Car Defogging Work in Summer?

[Nathan]

Simply turn on the warm air and rotate the air direction to blow towards the windshield for a while, and it should clear up. Below is an introduction to car defogging: 1. One-Button Defogging: For vehicles equipped with a one-button defogging function, you can activate it when fogging occurs for a more convenient and quicker solution. 2. Lower the Interior Temperature: Open the windows slightly or turn on the air conditioning to reduce the temperature difference between the inside and outside of the car. This not only reduces fogging but also improves air quality inside the car, preventing discomfort caused by sudden temperature changes and poor air circulation. For models with a sunroof, opening it can utilize the negative pressure ventilation principle, where the airflow over the roof while driving creates negative pressure inside the car, drawing out hot air and improving ventilation. 3. Air Conditioning AC Dehumidification: Lowering the interior temperature in winter can be too cold, so simply turn on the AC and increase the temperature setting. The dehumidification function of the AC can quickly eliminate fogging.
