Ford Wiring/Electrical :: 1999 Explorer V8 - Parking Lights Won't Turn Off
Sep 25, 2013
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.

I am beginning to think that I need a whole forum dedicated to my trucks wiring issues ... I finally got my reverse lights to work but my newest issue Is that while driving tonight i lost power to my parking lights, my instrument cluster lights, and my heat control lights... everything still works inside (gauges all act properly but they won't light up) and i still have turn signals and brake lights, and headlights. I really don't know where to start with this one. I don't have an owners manual so i can't figure out what fuses to check or what relays to look at. It is a 2007 f350 diesel....

2005 Super Duty 350. Getting ready to get my truck DOT-ed and I noticed the front amber side marker and parking lamps are not working (both in the headlight assembly). There is a fuse called "exterior lamps" that I believe these are on, the fuse is fine and all the rest of the exterior lamps on the truck work fine (all other markers, clearance lights and I.D. lamps on that same all inclusive circuit). Is there a special relay or something else I'm missing for these four front bulbs?

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.

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.

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).

My brake lights, turn signals, and flasher are not working in my truck. Is it a fuse and what fuse? Could it be a relay?

Dad borrowed truck and wired 7 pin trailer harness. Lights worked on truck/trailer for use but upon return the turn signals didnt work. Hazards and running and brake lights did work. Replaced TS flasher and Haz flasher. Still no signals. Pulled steering wheel and replaced turn signal cam only, not whole switch. Now no brake lights, no rear hazards or turn signals. Losing my marbles trying to follow schematic and using test light and mulit meter. All bulbs and fuses are good. Running lights and head lights working as well.

I just bought an 05 F250 XLT. I noticed tonight that the rear turn signals and brake lights don't 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.

What I am trying to do it put in 2 led spot light for added backing up light. What i want to do is have them turn on when put into reverse but also have a switch i can use to turn them on when not in reverse. Just need to know what relay I need and if it even can be done.
I was also thinking of just taping into the wiring harness and adding a wire that goes to the spot lights and another wire that goes to a switch that I could turn on and supply power to the light when not in reverse (I know it will light the revers light also) but is it ok to do that?

Turn signals work in front of truck. Running lights are working fine.
Same goes when trailer is connected on truck. What could be the problem.

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 have checked the fuses for the Hazard and the Turn Signals. Both look fine. I tried replacing the turn signal flasher (which was a task in itself). After all of this it is still not working. What else could it be? Simple short?

My truck just came out of the shop. Was in for spark plug change. My parking sensor button is lighted up with OFF. I tried pressing it but it stays in OFF and no beeping occurring when in reverse and there are objects behind me. What could it be? Fuse?

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.

Just bought an 04 Super duty with the factory plug 7pin and 4 pin plug. Checked the fuses and finally tracked down the 2 relays under the hood but can't seem to find anything wrong. Everything on the trailer works except for the running lights. Is there another fuse or something I have missed? Trailer works fine on my buddies Duramax and worked fine on my old 97.

Just picked up a 1999 F-150 XL, 4.2L V6, 5-Speed. Spent half the day rewiring the headlights back to factory as a previous owner did a bunch of wiring that made absolutely no sense. (Foglights or KC lights?). Anyway, works great with the exception that the headlights turn on when I turn the selector to just parking lights. I removed all but the factory wires under the hood. I haven't been behind the dash yet to check the headlight switch and I was hoping to avoid doing so. A fuse or relay that may be causing the issue? I don't have a service manual yet so I haven't been able to identify all the fuses under the hood.

Turn signals quit working on my 2006 E-150. Swapped out the relay under the dash and it did nothing. Also noticed the brake lights aren't working. The headlights and taillight a are working. I pulled the fuses under dash for the lights and they tested ok. I did notice the flasher relay was making clicking sounds intermittently even when not touching anything.

2000 F-250 Super Duty
I was replacing my headlights, which required me to splice in their lights to my parking lights, and I seem to have shutdown ALL my parking lights. I did a test after twisting my wires together and everything worked fine. Then I soldered and heat shrunk them and somewhere during that process I lost all the parking lights.
I checked the 8th fuse as per the manual (for Parking Lamps) with a multimeter and it checked out just fine.
Figured it was the time to ask the experts on here where I should go from here. Are there some other fuses I could be missing, or maybe some else I could do?
Solved: Bad fuse in the #8 slot in the Power Distribution Box (under the hood, near Cab, driver's side)...
