Electrical problem
1999 Lincoln Town Car V8 Two Wheel Drive Automatic 200k miles

Have Headlights, have brake lights, however no tail lights or markers? Checked every fuse under dash. Check fuses and relays under hood. Looked for a fusible link under driver side door threshold. Looked for a trouble code with an OBD scanner, found nothing?

When the switch is disconnected from the wiring harness I should have all lights controlled by the switch on. Headlights are on, Lights On Bell is ringing no tail lights? I've tried auto position as well as every other position.I've switched the light switch with a known working switch, same make & model. Apparently, the switch is not the issue?

Please advise-Thanks

HEADLIGHT SWITCH Disconnect headlight switch harness connector. Continuity should be as specified between terminals with switch in specified position. See HEADLIGHT SWITCH TEST table. See Fig. 2 . If continuity is not as specified, replace headlight switch.

There is a handful of fuses that need to be checked, also there is a lighting module that can be out as well.

Trace the wires shown in the diagram use an ohm meter, it should read below 5 ohms, if it reads high or OL, it is shorted to ground, this should blow the fuse for the tail lights. Have you checked that?

Or a wire may have corrodes inside the plastic, and this will not blow the fuse. Don't forget to check the ground!

Here are some wiring diagrams for you.

Please let us know happens so it will help others.

Best, Ken

The rear brake lights wont work. The middle brake light works. The Fuse is good and the lamps are good. There is no voltage going to the brake lights when the peddle is pressed.

Turn signals work ok? The lower brake lites are wired through the multifunction switch. The lower brake lites and turn use the same bulb filament, just not at the same time. If you need a wiring diagram holler?

Old post, maybe someone is having the same problem, just want to add some more help. No tail lights or front markers on my 1999 Lincoln town car. I could hear the relay clicking, measured 2.8 Vdc on brown wire connector C200 pin 22. Opened case, cold solder and burnt pad bellow relay, re flow solder, got B+ on that pin. If you can not hear the relay, check for B+ at pin 21 on connector C221, if no voltage, problem from light switch to that connector. Check fuse 31 under the dash. Check pics. Remember to disconnect battery terminals before removal, clean the pad before soldering (it has some clear isolating epoxy on from factory, be gentle to not damage board traces and pads), use a good soldering iron and flux, clean with alcohol and cover with dielectric grease, you should be fine.

My tail lights just stopped working. My parking lights wont come on, either. I have brake lights
turn singles ext. Just no back lights or parking lights, also the light above the rear plate doesnt
light up. It was all working fine then one evening I got pulled over by the HP, got a warning
for no tail lights. If I get caught out at night I turn on my flashers. I was told that the problem is probally in the headlamp swith, where
you turn on the lightd? If so, I, ll have to get a book, I have no clue how to get that out to replace it. If you can help, I, d be very grateful

thks for your attention, larry if I have to get a book, that will be no problem. I just hope that it isnt anything to do with the lighting module, one of fords better ideas I here that item is in the hundres of $$
thanks again for your time, respectfully,

larry stafford

It sounds like fuses, check those out first ! If it's the mod, go to your local auto parts store & find out what other years or type of cars
(Ford family) those things fit. Then call around to your local junk yards, ya should be able to get a cheaper price. Just make sure ya can return the part if it isn't working !

All of the tail lights are out but all other lights are working, headlights, break and interior. All the fuses are good.
What else should I check? Id rather not take it to the dealership to replace the lcm.

Thanks!

You'll need to check for power on the tan wire running to all of the taillights. This same circuit runs to all the parking lights also does the front parking light illuminate when switched on? Does the license plate light come on when head lights are switched on? If none of these lights come on and the bulbs are good (it unlikely all bulbs are bad) then the LCM light ting control module is faulty ( its located behind the dash in the center area).

My taillights do not work but my headlights, brake lights, and turnsignals all work. I have replaced the bulbs even though the bulbs appeared good, I have checked all the fuses and checked them twice, I have checked the grounding for the lights and it is good, the power for the taillights is the same wire as for the brake lights and turn signals so it shouldnt be a short.

First, the brake, turn & head lights are working. The problem is that the tail light & parking light do not work. I checked all the fuses located under the steering wheel and I replaced every light bulb in the front and tail assembly.

Thank you

The exterior and interior lights are controlled by the LCM(lighting control module) and will have a "B" codes stored for the problem, You need to scan for B codes with a capable scan tool. This is your starting point.

There is a bunch of fuses and a lighting module located under the dash that goes bad. Here is some guides and some wiring diagrams (below) so you can see what Im talking about and how to fix the problem. Also test through the switch as well.
