1.Adjust cabin temperature: The heater control valve ensures that the proper amount of hot coolant reaches the heater core, allowing you to control the desired cabin temperature.
2.Enable proper AC function: according to YourMechanic, when the air conditioner is in use, the heater control valve closes, preventing hot coolant from entering the heater core and interfering with the AC's ability to cool the air. This allows the alternating current to operate efficiently.
3.Defrosting and visibility: The heater system relies on heater control valves and is critical for defrosting windshields in cold weather to ensure clear visibility.
