It's called the "air door acuator"
It's up in the dash, next to the heater core.
There is no heater control valve, coolant flows through the heater core continously. Temperature is electronically controlled by a mode door inside the case that commonly breaks down
Here is what you need:

The heater control valve will be located in one of the heater hoses under the hood. Usually near the heater core box. If the lever is working don't assume the valve is. Sometimes you have to take it out of the hose and check it, the lever may move and not actually open the valve.

1998 mercury grand marquis heater doesnt work only cold air comes out the air cond works fine the enginecoolant is new, the engine doesnt overheat.

Either your heater control valve is not properly operating or your heater core is clogged. Locate the heater control valve under the hood, should be close to firewall on heater hose, have someone adjust temperature from hot to cold and see if you can see the heater control valve operating if so replace the heater core, if its not doing anything replace it(heater control valve).

I need to know where the heater control valve is located on my 1998 Toyota Sienna is located. I have Front and rear controls.

Hello brenda_peter: My name is Roger and I will help you. You will find the heater control valve under the hood. Locate the brake booster. Look to the left and you will see a valve with 3 hoses on it. The valve will also have a cable on the top of it. This is the valve you asked about. This is the only valve. It controls the front and rear heat. Should you need further help please just ask. Please rate the quality of your answer. This way I know it was helpful. Thank You for using Fix Ya. Roger

All i get from my heater is heat i cant turn the ac on, and when i turn off the heater it still blows hot air

Sounds like a stuck heater core valve. Find heater core valve. Under hood, find the two heater core hoses going into firewall. One of the hoses has a valve. Operate temperature control (full heat, then full cold) check that valve changes position. If not either replace valve or control system failure. Also, when temperature control in cold position, one hose should feel hot and the other cold. Temp fix: disable valve to close no heat or on heat.

1998 ford f150- heat issue

There is no heater valve on a 1998 ford F-150. The hoses for the heater lead directly from the engine and go to the heater case. PS The heater doors are all vacuum controlled so you might wanna look under the dash for any lines that might be disconnected
