There are 2 hoses going through the firewall from the engine, these are the coolant hoses to the heater core, one is 3/4" and one 5/8", the control valve should be in the larger line (3/4") which is the inlet, make sure that the valve has vacuum (heater on low), also check and see if both hoses get hot with the heater blower on low, if they do get hot your problem is not the heater control valve but the air temp control blend door actuator.

Most heater control valves are on or near the firewall behind the engine. Look for coolant hoses attached to a small metal piece. It also will have an arm that has a cable from inside the vehicle attached to it.
