Q:Is this located under hood behind engine on the top?
A:Hi Mike, glad to assist you! For assisting you further regarding the Factory Air Heater Control Valve (Part No. 74799), please provide us the year, make, model and engine size of your vehicle.
Q:my heat is notheating up in my car could this be one the problems.
A:This could be the cause of why your air is not heating up. A car produces hot air by letting hot anti-freeze pass through the heater core which then is pushed into the interior of the vehicle through your vents. The heater valve controls whether or not hot anti-freeze enters the heater core to warm the passing air. It could either be the heater valve that is not working properly or it could be the actual linkage that opens the valve.
