How to Turn on the Heater in a Car AC?

[McIris]

After starting the car, wait for the temperature indicator to reach the middle position, then turn on the heater after about 8-15 minutes (some cars have a red heating mode, while others use a sun symbol), and set the AC to internal circulation. Do not turn on the A/C switch because the heater utilizes the car's own heat cycle. The direction of the warm air is generally toward the front and the feet. The specific steps are as follows: 1. After starting the car, wait about 8-15 minutes until the water temperature rises to the normal level, then you can turn on the heater. 2. Adjust the AC circulation mode to internal circulation. 3. Switch to the heating mode, which is indicated by a red zone in some cars and a sun symbol in others. 4. Do not turn on the AC (do not activate the A/C switch) because the heater uses the car's own heat cycle. 5. Adjust the AC to a suitable setting and direct the airflow from the vents. 6. The warm air is usually directed toward the front and feet, while the cold air is directed forward.
