Damper Door?

wkramer on Sun March 29, 2009 9:32 AM User is offline

Year: 2003
Make: Lincoln
Model: Town Car

I have a 2003 Lincoln TC that I have been having A/C problems with. All hoses have been replaced, evaporator has been replaced, temperature sensor has been replaced. All controls work (compressor goes on when it should) and refrigerant is full. It still blows hot air when the A/C is running. Looking at internet searches has pointed out that a damper door that is not opening properly could cause this problem even if everything else is working properly. I have noticed that the metal hoses in the system do not get as icy cold as with my other cars when the A/C is running. Would the damper door not working also cause the metal hoses not to get as cold as they should too? Thanks,

Feel the suction line going from the compressor to the evap, should be cold. If not, you might be undercharged, or so much heat is blending in that it's sucking it up, then it could be the blend doors. They have a plastic "Ratchet type" mechanism, they break, but I don't know if you can see it behind the glove box, you can ask a dealer to bring the evap box up on his computer screen to get an idea where it is.. Some dealers are helpful these days.. Hope this helps..
