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.
View 10 RepliesFirst 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.
View 3 RepliesI 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.
View 8 RepliesI 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?
View 2 RepliesThe 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.
View 9 RepliesMy 1997 chevy suburban wouldn't start after being parked for a few days. the battery seemed to drained out so quickly and not because the lights were left on. The alternator was replaced less than two years ago. and the battery less than a year ago. I tried to jump start but it did now turn orver. What is the problem?

View 14 RepliesI have a 1990 F-350 7.3 lariat crew cab. The tail lights fail to work but all the turn signal and brake lights work. I changed the light switch located to the left of the steering wheel but that didn't solve the problem. all the fuses under the dash appear to be ok to. Is there another fuse for just the tail lights.

View 1 RepliesI 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.
When I turn the lights on , the dash lights go out on my 1988 k1500 silverado.
View 4 RepliesOur son has a 97 Chevy C/K pickup truck and told me about a problem that I thought was easy to solve, and we tried, but it wasn't. The driver's side front turn signal flashes fast. I checked the rear lights on that side and the turn signal wasn't working at all, let alone the tail lights, so I replaced the bulbs. They're the kind with the 2 filaments. I noticed the old bulbs were covered with some nasty yellow corrosion. Now the turn signal problem is the same and still no brake light on that side but he has tail lights at night. I tried to clean up the corrosion in the circuit board (none on the bottom light, which is the reverse light) with a neighbor's wire brush but it didn't change anything, so he suggested I change the circuit board.
View 6 RepliesI 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.
so I recently purchased a 2007 f350 SCSB and my reverse lights don't work. I am trying to trouble shoot the cause... So far I've replaced the bulbs and tested the plugs and im not receiving any power to them... Where to start to look for the problem?
View 3 RepliesI 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....

View 2 RepliesDad 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.
View 6 RepliesWhat 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?
