How to Turn on the Car Air Conditioner's External Circulation?
1 Answers
Methods to activate the car air conditioner's external circulation: 1. Locate the button with a car symbol in the air conditioning control area—the button with an arrow pointing from outside to inside the car. Press this button to turn on the external circulation. 2. Some cars do not have an external circulation button but only an internal circulation button. Typically, when the light on the internal circulation button is on, it indicates internal circulation; pressing it again to turn off the light switches to external circulation. The difference between internal and external circulation: When air is drawn from outside the car, it is in external circulation mode; if the air comes from inside the car, it is in internal circulation mode. During external circulation, the blower's air duct is connected to the outside, allowing air to be drawn in from outside. In internal circulation, a flap blocks the air duct leading outside, preventing the blower from drawing in external air.
