Why Does the Car Window Glass Fog Up in Summer?

[DeCamilla]

The reasons for car window glass fogging up in summer include: 1. The car's air conditioning temperature is set too low, causing a large temperature difference; 2. Incorrect air conditioning airflow direction, such as directing air towards the front windshield and side windows; 3. Cold glass coming into contact with high-temperature outside air, combined with high humidity, easily forming a layer of condensation on the outside. Solutions are: 1. For manual air conditioning models, simply turn the fan speed to maximum, turn on the A/C switch, set the temperature to the lowest, and press the front window defogger button to see the condensation gradually disappear. 2. For automatic air conditioning, press the AUTO switch, set the temperature to the lowest, and press the front window defogger button. 3. For models with rear window heating and defogging functions, pressing the rear window defogger button can speed up defogging and prevent further fogging.
