The heater control valve is under the hood on the passengers side of the motor and is located in one of the two garden size heater hoses entering the firewall and it is connected to a vacuum line which causes it to function. If. you want a picture go to ORielly.com and enter a search - it will give you a picture. The web site is http://www.oreillyauto.com/EW3/HomePage.do and then you will enter your information on the vehicle and search for heater control valve.
