03' LS heater control valve

Does anyone have a picture of this?
I'm being to told I need to replace this and my DATC module
Lincoln gave me part #'s but not sure what it looks like.
Any help would be appreciated.

Who is telling you this? Why do they think the DATC module is bad? It is uncommon for it to fail. It is very common for the DCCV (heater control valve) to fail.

Lincoln is telling me this. I trust these guys but I thought it was uncommon as well. I changed a senser and nothing helped. I took it to Lincoln and they said I needed a new heater conrol valve($147), and a DATC module almost ($450). I about died. I know I can fix mostly anything but couldn't find anyone else that sold them.
my car runs fine but can't get any hot air from the vents.
have any suggestions?

The DCCV needs tobe exercised during the summer months.

1) Turn the HEAT on Max with engine at the normal operating Temp.
2) Becarful and unscrew the heater core coolant bleed screw, it should flow a constant stream .

Caution coolant = 180f - you can turn the coolant flow off, by turning the heat off.
The heater core bleed hose is next to the coolant recovery tank, it should be long enough to put into the recovery tank while doing this test,

If theres no coolant flowing, the DCCV is stuck, or seized in the coolant off pos.

Did the test on the dash and it showed all 8's and all lights w/ no codes as if all is fine. I unplugged the hose and it seem to flow just fine when it had pressure.
Doesn't this tel me all is fine? do you think it's my heater control valve? I'm really lost now..
Thx

What do you mean when it has pressure?

It should have a constant flow from the Heater core bleed hose, this heated coolant provides you the Heat for driver & passenger control.

sorry for confusion. I unscrewed the plastic plug and it flowed just fine. I took the overflow cap off and the flow slowed down and then stopped. When I replaced the top then it would start flowing again. Vents still didn't blow hot air. No codes came up on the dash either

I suggest that you replace the DCCV first and see if that fixes it without changing the DATC.

Here's another test you can do. Unplug the electrical connector to the DCCV. With the connector unplugged, you should get full heat all of the time. If you don't then the DCCV is stuck closed. If you do, then the DATC may actually be bad.

Joegr has a very good suggestion in unplugging the DCCV to see if you get full heat on both sides of the dash. If not, feel the outlet hoses of the DCCV to see if there is flow of hot coolant out of the valve. It the outlets are not hot, see if the inlet is. If the inlet is hot and the outlets are not when the DCCV is unplugged, that pretty much conclusively condemns the DCCV.

There is a connector at the DCCV and another one that is mounted more near the upper passenger side of the radiator.
