Heater Control Valves help maintain the desired temperature in the cabin by controlling the flow of coolant through the Heater Hoses to the Heater Core. To work correctly they need accurate readings from the Coolant Temperature Sensors so ensure you have checked these for any issues when looking at the control valves.
