Lincoln Town Car Electrical Problems

    Perhaps the IAC (idle air control) valve? Common problem, but I don't know if it's ever intermittent.


    Your car doesn't have any wires but I believe the unit is in the same place.

    Couple of bolts, clean with carb cleaner or wd 40 or replace with Motorcraft unit.

    Hope that's it, good luck.

    Suggest that you clean the mass air flow sensor. Be careful while cleaning it. A squirt of electrical parts cleaner is usually enough to clean the little wires in the unit.
  • All lights work.....all fuses are fine. When I try to use the turn signal it doesn't flash. My mechanic says the LCM needs to be replaced...$750 at dealer...or junkyard then extra to have it re-programmed.

    Is there anything simpler and cheaper to try first? My dash lights have been flashing on/off for a few years now if the LCM is indeed bad and more problems will soon happen...maybe I should replace the LCM anyway? there anyway to determine if a used LCM is compatible or working....BEFORE I install it and pay the additional re-programming fee?

  • found a used LCM....$200 later all is far

    Yesterday i was changing a fuse on my 01 TC, everything was fine until a few minutes later, all my interior lights started going on and off and now i am unable to turn the car on, and all of the dashboard switches went crazy, (odometer, gas reading, temp) I can hear a noise coming from one of the relay fuses, may that be the problem??

    Usually stuff like that in my experience has been the result of a bad battery OR a bad battery connection. Carefully check and clean the battery cable connections if they're corroded.

    Good luck...Ed
  • Where can I get a replacement for the driver's side door pull with fake wood decorative backup. My fake wood is all scratched up from my fingernails, and the leather-coated pull is wearing thin. 2003 Town Car.

    You may be able to find a good one in an auto salvage yard. Also one may be listed on E-Bay.
  • I have a 2011 Town Car Signature Series and the low beam headlights stopped working. I have high beams that work and parking lights but no low beam. What could cause this?

    When you have less than 50,000 on the odometer, the factory warranty should be excersized.
  • That is out as an option. currently have 80K+
