    heater is REALLY broken now....

    Ok so the heater in my lincoln has now stopped working, even with the quick fix of unplugging the vacuum hose right behind the glove box that goes to a heater control dashpot of some kind. Now when I turn to "FLOOR" nothing happens but a strange noise in the dash like a sucking sound. Any ideas?

      well the sucking noise is the unhooked vacuum line, the no blower would be the thermal blower lockout. Its installed on one of the heater hoses under the hood, has the orange and black wires, and the blue and black vacuum lines. Jumper the wires together and seal off the vacuum hoses and you'll have heat again. The lack of control is a bad internal air temperature sensor, which is located under the dash pad above the glove box.

        damn Thain, you really know your stuff! So I can just remove that stupid "T" fitting with the vacuum lines all together? And by jumper you mean connect the two wires, right?

          Yes, thats what he means. Or you could just get a new part and fix it right. They don't cost that much and Ford still has them.

                yeah, I had one blow up on me, and the vacuum portion of it leaked horribly, so I never used it. The brandy new Chineese part lasted 2 or 3 weeks I think. Personally I don't mind using my brain enough to remember to not switch the heat on till after I've been driving a couple minutes. I actually have been meaning to experiment with the sensor out of a Mark VII and a relay circuit, but its been low priority. Might do it sometime when I get bored. The Mark VII piece is a sensor sort of like the ECM's temperature sensor, but its an on/off switch at 120F. Its low current so I'd need a relay, and its in a metal fitting that wont explode like the stock part. The relay would also carry the current to keep it from failing like the original does.

                Only reason I know as much as I do about the ATC is because I've had to fix mine. It had leaks, bad sensors, burned off vac lines from after the fire, bad soup can, etc. It used to be really horrible, but it works perfectly now. Its really not a complicated system once you get used to how it functions, only a couple things are failure prone and they all have different symptoms.
