Lincoln Town Car Heating / Cooling
Recently bought a low mileage black 87 Town Car. On my first few drives I noticed that the heat didn't work. All the heater hoses get hot (both sides of the heater control valve) etc and the heater core is warm to the touch. Based on information by an old Ford mechanic I dropped the glove box and found strange looking device. The body is a cylinder made of blue plastic with two mounting wings, and two vacuum hoses leadig to it, one small one in black vinyl and one larger one in clear vinyl. A cable from the HVAC panel connects to it. According to the mechanic the function of this device is to measure the temperature of the interior air and pass the information onto the automatic climatic control system. He says that the device is bad and providing bad information to the system the air is already warm enough which is why I am getting no heat. When I bypased the device the heat worked fine...I just couldn't turn it off.
So obviously I want to replace this device. My problem is when I call the Lincoln dealer I have no idea what to call the part and there is no part number stamped anywhere on the device, just a build date. Anyone know what to call this thing or better yet a part number?
Thanks in advance,
