Does the heater control valve affect the AC?
If the heater control valve fails or gets stuck, it will not be able to allow hot coolant into the heater core so that the heater can operate. If the heater does not have hot coolant the AC system will not be able to blow hot air, and the front defroster may not work. via
Why is my car blowing out cold air when the heat is on?
Low Coolant Level
The coolant (usually a mixture of water and antifreeze) in your engine doesn't just work to keep the engine from overheating: It's also the source of heat supporting the heating system. If there isn't enough coolant in your system, the heater core will blow cold air into your car. via
How long do heater control valves last?
How often do heater control valves need to be replaced? The original heater control valve for most vehicles should last for about 100,000 miles. Low-quality replacement heater control valves will more than likely fail much more quickly. It's worth noting that not all vehicles are equipped with a heater control valve. via
Will a bad heater control valve cause overheating?
While a lack of interior heat from a bad heater control valve is a serious enough problem, the real danger from a bad heater control valve is the possibility that enough coolant could leak out to cause your engine to overheat. via

Does coolant flow through heater core when thermostat is closed?
The thermostat is located between the engine and the radiator. This little temperature-sensitive spring valve stays closed during engine warm-up. When the thermostat is closed, it prevents coolant from leaving the engine and circulating through the radiator until the correct running temperature is reached. via
Does coolant flow through heater core when heater is off?
When you turn on the heat inside your car, air blows over the heater core, is warmed and comes into the cabin. Some vehicles have a heater valve that directs coolant through the heater core when the heat is on and bypasses the heater core when the heat is off. via
What is HO2S heater control circuit?

How do you test a heater control solenoid? (video)
Why is my car heater not getting hot enough?
Common causes are thermostat problems, heater core issues, jammed heater flaps, air bubbles, and low coolant levels. Some of these reasons are partly due to the age of your vehicle, while others are a result of poor vehicle maintenance. via
What controls the heat in a car?
The warmth from the engine goes from the radiator to the heater core, which basically acts as a heat exchanger. It allows coolant to flow through, and this flow of coolant is regulated by the heater control valve. As the engine's heat is carried by coolant into the heater core, the device starts to get warm. via
How do you test an expansion valve on a car?
