Lincoln Town Car Electrical Problems

My 85 Town Car has a multitude of issues, the two most serious at this time being it's inability to stay running while idling in my driveway while still in park. It runs, once started, for about 10 minutes while idling. If I drive it, it stays running for about an hour exactly every time then shuts off immediately (not a slow gradual loss of power, it's instantaneous). The second problem is that my interior lights won't turn off now. The lights were all working properly and then my car died after it had been running for less than 2 minutes. I was idling while waiting to make a turn and the car shut right off again and when i opened the door the lights came on as they normally do and didn't go off until they drained the battery. The battery has since been recharged and the lights will not go off unless I dissconnect the battery cables. Also when the car dies, it won't start back up right away. I know that the problem lies between the distributor cap and the starter because I know the starter is functioning properly and the distributor cap is brand new along with rotor, plugs, and wires. Also I installed a new ignition coil. The cap is not recieving a spark from the coil though, which is the cause if it's sudden death and failure to start. It's very random though, predictable, yet random. Sometimes I wait 10 min, other times it's an hour and a half. The sweet spot seems to be at 30 min however. If the car sits for a while it seems to start fine on the first shot.

  • I bought my 2004 Town car early this year, and the panel lights keep going out, without warning, intermittently. They come back after a few minutes, so when I've taken it in to the dealer, they can't 'reproduce' the problem! Also, the dimmer switch does not function..no dimming. Is there a connection?

    By the way, the service dept. is balking at replacing the dimmer switch. Does anyone know if it's such a big deal or that expensive? Thanks.
  • Isn't it under warranty?
  • Yes, it's still under warranty. The service rep gave me a lot of arguments when I saw the dimmer switch fault. It naturally makes me wonder.

    Black box on the Driver's side near the top of the fender. Our 1982 would behave like yours on a very hot day and placing ice cubes on top of the Black box caused the inards to cool and reset to normal. Perhaps the inard circuit breaker needs to be replaced and ask that your teck man check it out. Good Luck.
  • Do you know what this black box might be called?

    Not sure what it is called. Perhaps an Ignition Relay. I never opened it because all my problem was due to excessive heat so I applied some valuable ice cubes in a baggy on it. Hate warm whiskey.
  • Basically, I've checked the fuses,bulbs and break light switch. What else do I need to check til I find the problem?

    Check the turn signal unit. The flasher, of course turn signals, and brake lights operate through this unit. You'll have to remove the cover from the steering wheel to get to the unit.

    it was the keyless entry brain :blush:
  • Hey all, I'm a newbie and have SERIOUS issues with this car. Its a 1996 Lincoln Town carThe horn constantly blows if I return the fuse to its home- its like the alarm is triggered. The radio displays 'Phone' and only works after the key was in forward or backward position and is returned to take it out; and only till a door is opened. All other times it displays 'phone'. Any info would be so appreciated! Thanks for your time

    The horn blowing may be caused by a faulty key switch on the driver's side door. Try unlocking the car by using the key pad on the door. Disconnect the negative cable on the battery for a few seconds. This will reset the radio. If you have a remote control key fob, follow the instructions in the owners manual regarding setting of the alarm with the use the key fob. By the way, take a look at the front of the intake manifold on this car. The intake manifolds on these specific models have a tendency to crack at the front. If the manifold on you car has an aluminum piece across the front, your manifold has been replaced and you don't have to be concerned about the cracking issue.
  • Thank you, the switch will be my next move after I try the keypad. I thought about it, but had to hear it from someone else. I replaced the manifold myself last summer-it blew out suddenly one day. This car has had me stumped forever. it also has an extreme lean condition- I was going to start at the O2 sensors. Anyway, have a good one and thanks again
  • I have a beautiful 96 towncar...recently one of the warnings came up on dash saying door was ajar....figured it was rear driver side door but cannot seem to find any type of sensor(like the push button types in most cars on the doorjam)
    Totally annoying to drive car at night due to most interior lights staying on. Lights do go out after 20 min but it is a constant drain on battery....Anyone know where exactly to look for this door closing sensor????
    Thanks in advance!!!!!!
  • The headlights and running lights come on when I unlock the doors with either the keeyless or remote entry system. My 95 did not do that. Is this normal? The owner's manuel is silent about this. If it is abnormal, I'd like to correct it, to save the battery. Thanx
  • I've seen lots of 94 and older TCs with automatic headlight dimming. It is not on my 96 TC, and is not mentioned in the manuel.. Did they drop it as an option in 96? If not, does anyone have any info about it? I thought that the black unit in front of the rear view mirror was the eye, but it was the sensor for the compass. Thanx

    On you model TC, the headlights will come on when you use the key fob to unlock the car and the autolamp system is on. At the maximum autolamp setting, the lights should only stay on for about three minutes. The short period of time that the lights are on will not drain the battery.

    By the way, I discussed the lights-on issue with my pastor recently. When some of my fellow worshippers leave there headlights on just before church service stats, another member sends the pastor a note about the lights which he reads to the audience during the service. I reminded him that he nor the worshippers should worry about headlights that are left on for only a couple of hours. Hence, there is no need to read these notes during service. Headlights left on for two hours will not completely drain a good battery. And if the lights are left on and the battery is drained, we have jumping cables at the church and if the battery is suspect and does not hold enough current to start the car after two hours, this is a clear sign from above that the member needs a new battery.
  • Thanks for the reassurance that the headlights-on condition, when the car is remotely unlocked, is normal. I don't mind their being on, as long as it is normal. Thanks again
