#98 of 109 05 tc ac -questions
Jul 16, 2011 (10:16 am)
05 town car ac usually works great the first time I turn it on each day; it really cools down as it should on AUTO. Then, after I stop somewhere and it sits for awhile, it doesn't cool as quickly the next time I engage the ac. I have heard about blend door actuator problems and this may be it, but how do I know? i suspect it because it just seems that the air coming out is blended with warmer air. however, it may be something different, because in looking around under the dash for anything that might be an obvious problem, I've noticed the aluminum pipes(?) under there are so hot I can't ouch them...this doesn't sound right. At the very least those suckers are giving off a lot of heat. What are they and why are they so hot. Although I haven't c checked them before i use the ac first thing each morning, I know they can't possibly be hot. Please, anyone, can you help me? With each day over 100 degrees here in Oklahoma, and no job, I need to fix this at least cost possible.

I was able to find qute a bit of resources through lincolnsonline.com and youtube.com to identify where the bda is at and how to get to it. Quite a project requireing 2 persons, and several hours. It is hard to see, but can be viewed from the glove box by looking up and to the left. But the dash must come out to get to it.

Two years ago bought a good souhern 1997 Lincoln town car and air worked. Being it is a winter car in Florida, the air was not used much and last year when I started the car, the air did not work. Did take it to a shop advertising free diagnoses and they said the compresser was shot so I left it be because that did not make sense. Then I saw a troubleshooting program where a car (in this case it was a Jeep) that was taken to four different shops and only two of them diagnosed the problem with the air in this vehicle......was a relay (looked like a fuse) found in a box in the engine compartment.....relay was to send a signal to the system so the clutch would engage..........well, then I wonder if that might be my issue. I found a box that has markings for air relay but not sure how this box opens or how you access it to see if the relay it good or bad. Anyone have any thoughts on this and how I might check it out; would very much appreciate some good feedback.......would be something if that is all it was.

Yes there is a relay just behind the passengerv side valve cover. Hard to get to but it can be done. They are known for going bad. Mine is bad right now. It comes and goes.

I have a 1996 Town car. I have the same problem w/the blender/actuator door leaking on the passenger floor and NO HEAT. I LIVE IN BLIZZARD TERRITORY. After almost 2 years, PLEASE tell me you now know how to get the dash out? My mechanic is starting to put the screws back in and giving up. LOL I'M having so much trouble w/this. My mechanic DIED in the middle of repairing it. My 2nd mechanic's father died. We buried him this past Tuesday. HELP
#103 of 109 How do I get the dash out? Heater Core
Nov 25, 2011 (3:07 pm)
I have a 1996 Town car. We can't get the dash out. My mechanic thinks it's the heater core The other mechanic thinks it's a problem w/the blender/actuator door leaking on the passenger floor and NO HEAT. I LIVE IN BLIZZARD TERRITORY. PLEASE tell me how to get the dash out? My mechanic is starting to put the screws back in and giving up. LOL I'M having so much trouble w/this. My mechanic DIED in the middle of repairing it. After taking apart most of the dash, it had to be put back together and now I'm missing screws. My 2nd mechanic's father died. We buried him this past Tuesday. HELP
#104 of 109 Thumping/boiling sound coming from the dash.
Dec 06, 2012 (8:09 pm)
Just bought a 2005 TC and sometimes when started and at shutoff, I here a thumping/bubbling sound coming from what appears in the dash area or engine compartment. It doesn't do this always but sure seems to be annoying. Is this something I should be concerned with? I read in the owners manual that a noise from the traction control could make noise when the igition is turned off and is normal. Is this what I'm hearing? Thanks for any and all replys.

I have an 05 TC and that noise you hear is the vacuum operated blend doors on the climate control system actuating, ie, opening and closing and adjusting to whatever setting you system is set for. When an engine powers up vacuum is created and all vacuum operated devices then, in turn, are pulling that vacuum and doing whatever they are designed to do. When the engine is shut off the vacuum is lost, and the devices which depend on vac, lose their ability to maintain their settings, hence the blends doors moving, creaking, boiling, etc. It's normal, not to worry now that you understand it.

In Auto mode, heat works fine for first 20-30 minutes. As time goes by, cabin temp. begins to drop and I have to keep increasing the temperature to maintain a comfortable cabin temp. To maintain 70-72, I will eventually need to kick the temp up to the 80's.

Lincolns have a bad reputation when it comes to the climate control system which is frequently NOT under control. Frequently, the blend doors don't really blend properly and most all owners know better than to try to repair the problem--its a nightmare and takes a fortune in labor costs. This heat loss also works in reverse---When AC is engaged for first time on a 100 degree day, it will work fine . But, if the car is taken on short trips--on and off again . the AC cannot recover. In other words, it loses its cooling ability and the reason why is because the heater core and the AC evaporator are right next to each other. As the engine reaches operating temp, the heater core is HOT, and ready for heat if you need it. It doesn't realize that its already 100 outside. So, the effeciency of the AC is compromised by sitting right next to the heater. So, I have noticed the heat loss problem on my 05 Lincoln too. I have noticed that if I set the heat for 90 and hit "auto" the AC will automatically engage. I then must punch AC to "OFF" in order not to compromise the heat with a cold evaporator (it doesn't know it only 23 degrees outside). One other thing you can do is to select the "heat to floor" on manual mode at first and thereby not selecting Auto, which engages the AC. Hope this helps. It's a very poor system on a really nice car. Lastly, even though it's a poor system, keep in mind that "Auto" Climate control works on a thermostat set-up just like in the house. When the Thermostat is satisfied at 72, it will shut off heat output through the vent. What you get is unheated air until the the thermometer drops below a certain degree to signal "start up again in order to get back to 72." So, how far does it have to drop before reactivating? Good question. My suspicion is that the calibration and sensitivity is also sadly lacking. If working at all, it should eventually start putting out heat to get back to 72, but probably you're going to be cold until it finally gets there, so you crank it up to 80-85. If I had known this about this system, I would never have bought my Lioncoln! I prefer one heat/cool knob that goes from blue to red, and one fan knob that goes from low to high--best arrangement even though old school.
