No Tail Lights

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!

Electrical problem
1998 Lincoln Town Car V8 Two Wheel Drive Automatic 110,00 miles

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

its your headlight module,but make sure you cheack all your fuses well with a test light.p.s not sure where its at myself right off hand.

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.

Hi
Do front park lamps and side marker come on? Also does license lamp work?
Let me know
Thanks for Donate

All of the lights in the front work but the liscense plate light does not work

O.K. have a wiring problem possible S292 a splice connection of a Brown wire that carrys volts to rear tail and license. Located dash harness Breakout to Air bag Electronic Sensor. Sensor under right side dash in front of air recirculation duct.

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.

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. Please help, I'm limited to driving during the day-light hours and driving with my emergency flasher lights on at night.

Thank you

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.

Thanks you so much, it was the lighting control module that went out, got it fixed saved me a ton. Thanks 2Carpros kick ass wbesite

My taillights and park lights do not work. my headlights, back-up lights, brake lights, and signal lights are working just fine.

The first suspect is the head light switch, . . . more specifically burned contacts and overheated connector terminals. An additional clue might be the dash lights also don't work. Next would be a broken wire or corroded connector terminal, but the location would have to be pretty limited to affect all the individual lights.

Don't overlook something as simple as a blown fuse. This is a better suspect if you have a trailer wiring harness on the car.

I need the wiring for the lighting system

updated:

tail lights and brake lights

Welcome to the forum, wiring diagram for which vehicle system? Ignition--fuel-- other?

The autozone site has free wiring diagrams. You have to register the vehicle, but, it is free. Then Click on vehicle repair info.

I'd be glad to post a diagram, if I can find it, just need to know what system.

OK, can you be a little more specific? headlights-- tail-lights-- brake lites-- dash lites-- interior lites?

no exterior lites working, checked all bulbs, replaced head lite switch, still no exterior lites.While replacing head lite switch all running lites came on temporary . After relacing head lite switch only one front running lite works.Tested orange/black incomeing power wire ok.Pin H on lite switch has power when switch is on, no power when turned off. What do I do now? Please HELP me. Carl

Crown Victoria, Grand Marquis & Town Car Potentiometer is attached to headlight switch. Unplug potentiometer connector. Connect self-powered test light between connector circuit No. 57 (Black wire) and switch bracket. If continuity does not exist, replace potentiometer. If continuity exists, go to next step. Continuity should exist between connector circuits No. 220 (Dark Blue/Orange wire) and 57 (Black wire) after rotating autolamp control switch knob from OFF to ON position. Measure resistance between circuits No. 217 (Dark Blue/Orange wire) and No. 57 (Black wire) while rotating switch from OFF position to maximum time delay. Resistance should gradually increase from 2500-4500 ohms (OFF position) to 140,000-260,000 ohms (maximum time delay). If test results are not as specified, replace potentiometer assembly.

Unplug connector at autolamp relay. Connect test light between ground and Red/Yellow wire. Voltage should be present with switch in ON position. If voltage does not exist, repair Red/Yellow wire to headlight switch and to high-low beam relay

First I want toThank you for all your help. If I wasn't strapped for money I would've paid more for your service. I'm very pleased. We have successfully completed potentiometer test and have continuity and ohms.I see autolamp delay switch-- can you help me find autolamp relay switch so I can unplug connector and connect test lite between ground and red/yellow wire where I hope to find voltage while switch is on.If no voltage found you say repair red/yellow wire at head lite switch and high/low beam relay, do you mean run a jumper wire (different wire). Thanks Carl Raney

try looking Behind left side of instrument panel, above steering column

If cannot locate the short replacing the wire would be the easiest to do

I have a 1987 Lincoln Towncar that has developed a problem with the tail lights: they aren't on. The brake lights and turn indicators work but not the tail lights. Also, the light over the license plate is out.

I've replaced all the fuses and bulbs but still have the same problem. The fuse that handles the tail lights also handles other things and all the other things work okay.

I'm dumbfounded. Any suggestions?

Best regards,
Ron Decker

You probably lost the ground circuit-because if its short to ground it will blow the fuse-also could be an open circuit to the T/lites. start by removing carpet and look for a quick disconnect going back to the lites. Test for power.

BTW do you have parking lites up front?

Yes, I have all the other lights as well. I'll take a gander at the under-carpet wiring. Also, when I left work yesterday my battery was dead. I got a jump and as I was waiting the handles on the jumper cables began to melt! I disconnected the batteries and looked around and finally found the headlights were pulling a lot of amps and they weren't on!

In any event, I got the car started and drove about a mile when the transmission gave a rather loud hiccup and died right in the middle of Houston traffic. I cruised to a gas station where I parked and eventually got the car home later that evening.

I am as perplexed as a man can be about all this. It seems the new problem just sort of popped up (don't know if that's possible) all on it's own.

Thanks for the suggestions; I'll give it a try and let you know what I find.

Best regards,
Ron
