Ford Wiring/Electrical :: 2000 - Tail Light Won't Turn Off - Headlights Won't Turn On?
Dec 7, 2014
The tail lights do not turn off- the head lights do not turn on. every fuse was pulled and still the tail lights stayed on. Headlight switch was swapped out with a new one to eliminate it with no different result. No modifications known to have been made to the electrical system. This thing did spend a lot of time in NY state, so corrosion is likely. But this does not explain how/why the tail lights would stay on even if the headlight switch was off... IMO this would have to be an ignition switch issue.

First off my driver side brake light with stop working. I took it apart to try and find the short. In the process I shorted out all my running lights tail lights and brake lights and turn signals I think also. While I was looking for the short, turn signal wire from my tail light touched the frame and grounded out and that's when all the lights died . My tail lights are some cheap trailer lights without reverse lights. I pulled headlight switch from another Ford truck I have. On the harness connector that connects to the switch which wires should read what when I test with a voltmeter?I checked the fuses in the power distribution box under the hood and they were good. Truck has a flat bed so I don't know if that matters with the wiring, I suspect it's different then a normal bed truck. Wiring on the bed is old, maybe from 94. I am unexperienced with electrical.

The truck is parked in the drive. I noticed when the truck had been parked in the drive I noticed that the tail lights came on and then about 20 seconds later turned off. I checked that the ignition was off, doors were completely closed, etc. It has happened several times. I'm worried the there is an electrical problem that might drain the battery.

I just bought an 05 F250 XLT. I noticed tonight that the rear turn signals and brake lights dont work.
the front turn signals work fine, although they flash fast. I know that usually means a light on its way out. neither taillight flashes though, which puzzles me.
my second issue is that, of the 3 brake lights, only the high mounted light illuminates when I hit the brakes.

1994 Econoline E350. All the other lights work but on the front right the turn signal light flashes but the Hazard lite will not flash. I check for power at the wire at the light and there is none.

I installed LED tail lights a few months ago, now all of a sudden the passenger side does not light for brakes or turn signals. The lights came with resistors that I put in when installing and the adhesive wore out and they were dangling in the truck frame. The wires connecting the resistors to the light were damaged. I taped the exposed wires and secured them a with a heavier tape, but taping did not work. I also tried switching the resistor packs with the driver side to see if it was them that have an open winding, but they are still operable.
I narrowed it down to wiring between the trailer hook up and passenger light assembly in the electrical circuit. I plugged an LED light bar into the trailer connection and the same problem occurred (running lights come on, but no turn signal or brake light). Where could there be a short? Or is this circuit fused somewhere that the running lights come on but a separate fused circuit triggers the higher voltage for LEDs.

Okay, my 1986 f150 with a 351w (non-feedback carbed) Has no lights on the cluster, and none of the gauges work (haven't tested the speedo yet, truck is not registered yet).
I also have a minor issue with the turn signals... Fronts work, no rears. The left turn indicator light on the dash does not come on but the right turn one does. All my "primary lights" (markers, tail, headlights) work fine. I have not yet tested the brake lights.
Fuses all look good, truck did have some roof leaks. I've done some research, does this sound like the dreaded voltage regulator issue for the gauges?
My assumption for the left turn indicator light is that there is a replaceable bulb in the dash (probably blown), is that right? Rear signals might be wiring (PO installed his own trailer wiring) or bulbs? haven't gotten that far into it yet...

I have a unique problem with my newly acquired 71 F250. The left brake does illuminate when the brake is pressed but when the right turn signal if activated the left brake light does come on. The left flasher light also does not work. All other rear ligh function are normal. I am assuming I have a short or a wiring issue just wanted to know if there was any common item that might be know about this topic. The bulbs are all new. The reverse lights do not work either but pretty for sure its unrelated.

I have a 2000 Ford F250 lariat 7.3 .... This vehicle has an aftermarket double din stereo pillar gauges for Pyro meter and transmission temp and has also had a snowplow attached but since re moved since I purchased it. It also has H ID headlights, which are run by the passenger side headlight connection.
The problem I'm having is that whenever I turn on the parking lights it is blowing the number eight fuse under the hood. Which is giving me no dash lights running lights parking lights or taillights. Initially the fuse would last for a few minutes and then burn out. I should also add that the trailer wiring harness doesn't work either and the driver side headlight will work sporadically.

85 f150. My driver side brake light and turn signal in the back quit working. The tail light works tho which is a different filament. The bulb is good and I changed the flasher relay...the circle thing in the fuse panel. Everything else works just fine. looking for a starting point.

The tail light indicator on my BMW will not turn off. I replaced all the bulbs and it did not go out. I also did an experiment and swapped all the driver side rear lights with the passenger side lights. And the indicator light did not turn off. Is there a fuse I can pull? Is there a ground short?

My 1999 Ford Ranger XLT, 6 cylinder, auto trans, with 134K miles has an electric problem. When I turn the key to the 'on' position, all dash lights show normal, headlights work, radio plays, etc. But when I turn the key to the 'start' position, all electric power is lost. The power remains lost until I disconnect and reconnect the battery ground wire. After reconnecting, I again have power until the key is turned to the 'start' position. I was able to jump start the truck, so I assumed I needed a new battery. I bought one a week ago, and was back to normal until today. The truck started, I drove 4 miles to the grocery store, and then I found myself back to square 1 (i.e., the no-start situation).

I have a 1997 F150. I installed a trailer towing kit round 7 pin. I followed the instruction and replaced three different fuses after installation. The passenger side turn signal will not work. I replaced the bulb. The brake light works and the bulb is on when the lights are on it just will not blink. When the turnsignal is on it clicks very quickly.

I have a 97 F250 HD. Wiring the rear tail lights. When we bought it the had cut off the wires going to both sides of the rear lighting assemblys and I was wondering what wire went to what i have the left turn signal working just can't seem to get the brake/back up light to work on that side and i can't figure out how to get the right side going either.

2010 F-250 14,000 miles, gas engine with Knapheide utility bed. Tilt wheel has been kept in the up position from day 1.
The problem:
No rear brake lights.
No high mount brake light.
No rear turn signals.
No rear hazard flashing lights.
All trailer lights work.
All other truck lights work.
Things checked: Fuses all OK. Visual inspection of multi-function switch. Looks clean. Brake switch at brake pedal has power on one wire. Jumpered the other wire-no brake lights.
I need to haul my trailer and am nervous when I see a Savannah, GA metro police car.

Wipers work in all modes, but won't shut off. I was told there should be a shut off in the wiper motor that's not working. Would I be able to splice in a shut off switch, where is the best place?

I'm working on a 289 from a 65 Fairlane; When I attempt to start the engine it will turn over however, it will not start. I can switch it on and jump it with a screw driver and it starts right up. It started once with the key so I don't think it's the wiring. I don't want to start buying items chasing the problem when I don't know the answer. I have a new battery.

My turn signals will not work with the engine running. With the engine off they will. With the engine running if I move the ignition like I am going to turn it off they work.. Is it the ignition switch or ign cylinder....

I must be missing something here. Where is the flasher for the turn signals? It isn't the two relays behind the radio is it?

I have a 2006 f150. Both front turn signals do not work. I replaced bulbs still nothing. There back signals do work. They blink really fast.

I just bought a 99 Explorer v8 2wd to replace my aging aerostar and to tow my boat. I already knew it had this problem and a destroyed rear diff when I bought it, I figured this would be the easiest problem with just a new switch. I was wrong.
pulled the fuze
pulled the headlight switch
pulled the relays at: power dist. box, keyless entery/alarm?, the box under the dash
disconnected the harness from the GEM behind the dash and from the keyless entery/alarm
Lights only go out when I pull the park lamp relay. I know what you may be thinking. But no. Its still not gonna be that easy. The relay is not bad or being activated. Its just acting as a jumper from pin 4 to 3. So out comes the test light.
At the park lamp relay (without the relay in)on the relay module I get power at 1, 5, and 4. When I ground 2 with the test light, the headlight relay kickes on. Which seems normal to me by my assumption of how the system works. Which is that these relays are only for the RAP module to flash the lights by grounding the 2 pin. Anyway... I think I've narrowed it down.
According to the wiring diagrams, the 4 pin should only get power from the headlight switch and the GEM from a white/black stripe wire. With the relay in (only to jump the power)I have unplugged both the headlight switch and GEM, and the lights stay on and there is power at 4. I figured the white/black wire may have a short to 12v and I would just bypass it. Then today I can disconnect the battery, then reconnect it and the lights will stay off. Keep in mind all other relays are out and everything is unplugged. If I plug the headlight switch back in, cycle the switch, the lights will go on and off correctly, but will eventually stay on. Even after removing the head light switch.
Does the white/black wire go to anything other than the switch, GEM, or relay. It doesn't say so in the diagram but I can't figure out why its getting power intermittently. Still thinking it could be a short I did a wiggle test on the dash harness to try to get them to come on if off or off if on. Nothing.
