Whether to use internal or external air circulation when it rains and fogs up depends on the specific situation. If you are using air conditioning to defog in the summer, the driver can switch the air circulation mode to internal to reduce air humidity. If you are using warm air to defog in the winter, the driver can first switch the air circulation mode to external to minimize the temperature difference between the inside and outside of the car, wait a few minutes, and then switch to internal circulation mode. However, in special circumstances such as traffic jams or heavy dust, it is recommended to use the internal circulation mode. Summer defogging method using air conditioning.
