#1 of 109 No heat in my Town Car
Oct 07, 2007 (6:23 pm)
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,

Go to the Lincoln dealer. At the parts counter, they have a parts list for the heater components which they can pull-up on the computer. They can select each part on the list and pull-up the pictorial for the part. Describe your part to them, face-to-face, and they should be able to find the part number and get the part for you.

Hello, I have the same problem as you with my heater control on the Lincol Town Car 88. Did you figure out what's the name of the part you need to repair it? Is that difficult to repair or to find that sensor?
I really need that heater to work this winter but I want to repair it myself.
Please let me know.
#4 of 109 Climate Control: Blowing continuous hot. Diagnostics?
Dec 19, 2007 (12:27 pm)
I have a 1996 Lincoln Town car. The climate control system is blowing full hot all the time, regardless of the temp set in the unit. In my research on the internet, I've read about other with the same problem who have replaced the control head and didn't solve the problem. Luckily it's winter here, so I can live with it for awhile.
Have you encountered this problem before. Would you be able to point me to the solution?
I've also read about diagnostic procedures for this unit. Is there a guide I can access with these procedures to help me determine the health of the control head before investing in the replacement?
Thanks - DIYERR

Yes, the unit is called a control head. I replaced mine and it was very simple. The biggest problem was finding a Lincoln dealer who would work with me. Most of them wanted to say "That car's too old..we have no parts for it, go to a junkyard." Fortunately I work at a parts store so I told one dealer if you want my business, work with me. He found the part in five minutes and had it to me the next day. It was like 30 bucks with a twenty percent trade discount. I'll try to find the box for the part and get the part number. I think its still out in the garage.
The fix was very easy. I think there were eight screws that hold the dash pad to the car (Two are in the vents at the windshield). Some required a stubby screw driver. The part itself was a matter of two vacuum lines and a couple bolts. I think it took twenty minutes start to finish to do the job.
As for the other issue of heat only working on "high" I am not sure I understand your problem but here's what I do know based on working on other Fords I've owned. There's a part called the "Blower motor resistor" usually mounted on the AC box under the hood. Trace the wires from the heater controls to the BMR. When the fan is set to "high" current goes to one tab at full strength. When you turn down the fan the blower motor resistor cuts current to lower fan speed. If your heat works only with the fan on high, I'd bet tap water to a case of Corona it's your blower motor resistor. This is normally about a twenty dollar part and takes ten minutes to replace if you are even borderline handy. You should be able to get one at a decent parts house (Carquest, NAPA etc. as opposed to Pep Boys, Auto Zone, etc) or you should be able to track one down on line by using "Blower motor resistor 1988 Lincoln Town Car"

Sorry, I wasn't clear. The system will only emit "high" heat; the fan and various floor, panel, defrost settings change appropriately. The only climate control problem is that regardless of the temperature set in the unit, it only provides hot air even when set at the lowest temp.
I read another post on a different site where the person replaced the control head and it didn't fix the problem, so if there are diagnostics available that will help me determine whether the control head is really bad or not, that would help.
Where did you get a control head for $30? The initial price I was given was over $600. The car is a '96 Lincoln Town Car.
With this additional info, does any further advice come to mind?

#8 of 109 96 Town Car heat inop sounds like vacuum motor cycling under dash
Dec 27, 2007 (8:18 am)
I have a 96 Town Car, my wife and I use it to keep the good cars off the road in the winter. This is no good without heat. Even with the heat turned off you hear what sounds like a vacuum motor cycling under the dash. On the odd occasion it cycles and stays in the proper orientation you get copious ammounts of heat; heat runs without any regard to thermostat (climate control) setting. Has anyone experienced this? I can't get it to the shop till Monday and I'd like heat before then.
Thanks in advance.
#9 of 109 1988 Lincoln Town Car Blower Motor works intermittently.
Jan 03, 2008 (10:39 am)
My 1988 Lincoln Town Car Blower Motor stops working at times. If the switch is left on, it would suddenly come on. Sometimes it takes a few days before it starts working again. When I first purxhased the car several years ago, in order that the heat work, my mechanic removed the vacumn hose that is attached just under the glove box so that hot air would flow through the system. He told me I would have to reconnect the hose whenever I wanted the air condition on, in order that cold air flow through the system. I do not believe that this has anything to do with the blower motor not working now, but I thought I'd mention this as well..
Is the problem with the blower motor due to the resistor that controlls the blower motor speeds. If so, where is this resistor located?
I appreciate your help.

Perhaps the windings on the motor are corroded. Apply Carbon Tetrachloride to the windings to clean the corrosion off.
