Which Air Setting to Use for Defogging Car Windows?

[MacHarrison]

Both warm and cool air in a car can be used for defogging. Below are the relevant introductions about defogging: 1. Cold Weather: If the weather is cold, it is recommended to use warm air for defogging. The method is to first start the air conditioning, adjust the temperature to the warm air setting, and simultaneously set the air conditioning switch to the defogging mode. The hot air produced by the air conditioning will dry the fog inside the car. 2. Perform While Parked: Most modern car air conditioning systems have a dehumidification function, so you can turn on the cool air dehumidification mode in the car. This will quickly dissipate the fog on the windows, with lasting and fast results. However, when initially using warm air for defogging, the fog may worsen temporarily, but it will improve shortly. Therefore, if conditions permit, it is advisable to perform warm air defogging while the car is parked.
