I have a '95 dually and it has small yellow running lights on the rear fenders. The only time those lights will come on is when the headlights are on (or parking lights) and I put it in reverse. Not sure, but I would have guessed they are supposed to on when the lights are on and go out when the truck is put in reverse.
View 5 RepliesJust 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.
View 14 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 a 2004 Ford F-150 lariat with a bit of a problem. My running lights (not sure if correct term, I'm talking about the tail lights' illumination that stays on while you drive at night) are not working. My headlights and parking lights do work, and my brake lights and turning signals also work. I have put in a brand new brake light switch and checked every fuse and relay, but no luck.
View 6 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 9 RepliesMy steering wheel lights r out and need to know which wire runs power to those. also the led in my headlight switch is very dim.I checked the wiring and all the wires check out with high 11's and high 12 volts.i checked the volts at the led in the switch and it read 2.18 v.i have another light switch from the salvage yard and the same thing. which wire powers that light. also, the light only comes on when the key is in the on position or back for accessory. if i just turn the lights on it wont lite, only with key in ignition in those positions. truck is a 2000 f350 xlt dually.....

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 6 RepliesI have a 2011, F-350, Lariat, Crew Cab, 4x4, 6.7 Stroker. I have asked if any way to disable the automatic feature that turns on the marker lights when opening a door. That has been sometime back and nobody seemed to know. I have checked with Ford and their response was that if the truck was equipped with the "Police Package" that it could be done.
There has to be a way to disable a relay, cut some wire or something to stop the lights from being turned on automatically. Maybe duct tape over the door switch?
I was replacing the dome light in my 06 Ford F350. I tested the light and it worked then while screwing it back in, the lights when out and then the radio. I suspect it may be a fuse, but have yet to find the culprit.
View 2 RepliesLooking for a schematic on this truck,standard cab diesel. I have a dead short on exterior lamp fuse. I have no tail lights, running lights, door ajar light is also on.
View 4 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 Replies1998 Expedition EB, the lights on my running boards do not work. Checked online and can not locate the fuse for them, checked the lamps and found one that is burnt out. Here's the dumb question, if one bulb is out will that make the other three not work, something like the Christmas light strings?
View 4 RepliesThe front running lights come on immediately, but the tail and side running lights take their time coming on (usually 10 to 20 seconds later. 95 Ford E-350. Is their a relay that could cause this issue?
View 1 Replies2005 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?
View 1 RepliesMy new body style f150 , all the rear lights have quit working.whats really odd is at first it was the left signal then the right then everything. All bulbs are good. If I pull the bulb out and test for voltage i get voltage, I replace the bulb and test again.....NOTHING. I took the rear ground off and cleaned it up, test fusses . Don't know what to do from here.

2014 super duty lariat
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.
I have a 1983 E350 RV with a 460 engine. It would appear that many "Mechanics" have altered the wiring in different ways. That being said I think the charging and starting electrics are fairly untouched. My issue is that once it has been running for a while the interior lights start to fluctuate so does the radio display. The AC fan speeds up and slows down and I feel like there is not enough gas being pumped up too due to some coughing and sputtering. When I press the brakes the radio stops playing and if I have the AC on it gets worse. Today I changed the voltage regulator and it made no difference. This vehicle has two batteries, one for starting the van like normal and one to run the coach part. The alternator charges both. I think it must be a bad ground somewhere but not sure where to start.
View 2 RepliesMy 96 F-350 Crew Cab driver rear door lock is stuck in the locked position. I don't have a cause but do now notice that the pass door lock will not operate with the lock/unlock switch. The rear solenoids seem dead. Front door locks are working.
I tried to put a 10-32 coupling nut on the lock riser and pull. The down position is now 1/8-1/4" higher than normal. This thing is really stuck and is really bad.
So before I start pulling the rear seat and trying to remove the door panel from a closed door; how I might unlock this door? It would be a lot easier to get the panel off if it is open.
I have no left rear signal or brake lights. The right side works fine and both left/right tail lights work fine, just no left brake or signal. I checked for broken wires and can not find anything. 1992 Ford E50 7.5L.
