Which Button is the Car Air Conditioning Heater?

[VanAmara]

Car air conditioning heating button is generally displayed as a thermometer or has blue and red on both sides. The red side is for heating, and the blue side is for cooling. By turning the knob, the red area gradually increases the temperature, while the blue area decreases the temperature. Automatic air conditioning allows the owner to set a temperature, then press the AUTO button, and it will automatically adjust according to the car's temperature. When using the heater, there is no need to turn on the AC switch because the heater utilizes the heat emitted by the engine coolant for heating. After turning on the heater, it should be set to recirculation mode. When the heater is first turned on, avoid directing the airflow directly at the head, and the car window should be opened slightly to allow air to flow through the small gap, which is better for the occupants.
