How to change heat control valve on Linc ls v8 00

code p 2104 refers to throttle actuator control(TAC) system--forced idle mode===causes ---wiring--TAC motor--ALL sensor--ECM
codes p 2111 refers to throttle actuator control (TAC) system--actuator stuck open====causes --throttle body--throttle valve tight tight/ sticking
also refers to TAC system --circuit malfunction=== causes wiring short to positive ---short to ground ---TP sensor ---ECM
also refers to brake vacuum---implausible signal====causes ---wiring--- vacuum sensor--- mechanical fault

You must wait for the thermostat to open up, crank your heater on full, you will get only cold air once the thermostat opens it will start to heat up, heather runing wait for thermostat to open youll see your coolant bottle bubble up and go down , then you loosen the bleeding valve if you got one, cooling system service should be done all together , change thermostat,flush the coolant system, replace hoses if needed, if thermostat is shut and wont open up your more likely will blow a hose from the pressure .ty

It would indicate a bad hot water valve on the hoses connected to the heater core.

If your talking about the heat inside the car, yes. It is vacuum operated. On the passenger side. The hoses are about 1 inch in diameter. The valve is spliced in one of them. Make sure the vacuum is present before replacing.

It is located at the inlet to the Evaporator core, most likely behind the glove box insert area.

Look for a hose to the intake or call anypartstr...they have details of all cars

Thermostat has nothing to do with the heat

You have a coolant control valve down low under
the a/c drier on the passenger side, bolted to the
radiator shroud

I have that car,very complicated vehicle,one of the
most high tech ford has every made

Beside that valve there are several other possiblities,
mostly all electronic

Need the experience & all the diagnostic manuals or
I hate to say it,but maybe a dealer,not many shops will
work on a ford or an LS

Have it checked for a broken blend door actuator shaft.

might have to replace the whole control panel

maybe you won't need to. On the fire wall you will see 2 hoses an inlet and an outlet.that go directly into the heater core. Sometimes the heater core is clogged. disconnect the hoses and use a water hose running at only a moderate flow. put it into one of the the inlet of the heater core and run water until you see clear coolant. Then do it on the outlet and run it until the coolant is clear. you are trying to remove any clogs the heater may have. if this does not work, check the heater control valve.move the temperature slider the one to control the temp inside the car. and see if you can hear anything move. Check to see what type it is it can be a vacuum controled vavle, or a cable hooked on to the valve or an electronic controled valve. if it is a vacuum controled valve, you can check to see if a vacuume hose is disconnected, if it is a cable type valve,check it by moving the temperature control inside the car open it and close it with your fingers if you can see it. But most likely it may be the heater core thats clogged.
