Look under the hood and follow the heater hoses and the valve will be in line in one of the hoses. Usually in near the heater core. If you see it and the cable or vacuum line does move the lever the valve could still be bad. To check take valve out and manually move the control and make sure the flap opens and closes. The flap may not work even though the lever is moving. Good Luck.

How to check the heater control valve on 1994 mercury villager. no heat


Hi, to check the heater water valve, start the car and turn the heater on. Go to the valve and pull the vacuum hose off the valve (see picture of valve below). You should hear the hose leak and see the rod come out of the vacuum actuator and turn the lever on the control valve. If this is not your problem, please see my tip at http://www.fixya.com/cars/r6235876-no_heat_fan_blowing_cold_air , and let me know if you have any questions.

Heater is blowing cold air,


Check operation of heater coolant control valve, and it's associated remote control mechanism.
Check that both inlet and return heater hose is equally warm, as this indicates coolant flow through the heater core.
If no coolant flow:-
Check cooling system is correctly filled, taking care to bleed off any air locks from the system as necessary (with heater coolant valve open);
Check heater core is not blocked.

Sounds like the blend door that diverts air flow inside the heater box is not working, or, the heater control valve on the heater hoses in the engine bay is not closing.
