Ford Super Duty (1999-2016) :: Adding Running Lights After Some Pop Up Noise Now No Turn Signals / Hazard / Brake Light?
Jul 4, 2011
I was adding some more running lights today and tried to tie in to the front running/turn signal light. Next thing I know I hear a pop and now no turn signals, hazards or brake lights on my 99 F250 SD V10. My 3rd (center) brake light does work though when I press the brake, it's just the tail brake lights that dont work.
I can't find a blown fuse for the turn signals or brake lights (not really sure which fuse box it's in since the manual doesn't tell me what fuse is what)
I however did find what I'm guessing are the flashers behind the radio. What might have went wrong where before I start dumping money in to flashers and relays.
The next question is, can I jump in to the marker/turn signals and add another single LED light to them off the front? If I can which color wire does what?

I have a 2006 F250 Superduty 4x4 that the brake lights hazards and turn signals have stopped working in the rear.. The middle cab brake light does not work either.. The running lights do work as well as the turn signal and all lights in the front.. I also checked the trailer plugs and both work for running brake and signal lights.. I have checked all fuses under the hood as well under the dash with a test light and i have nothing blown.. I have replaced the Brake switch as well as the flasher module under the dash and picked up a new multifunction switch (Turn signal/hazard) and that didn't work either.. I'm stumped at this point.. I have not checked the bulbs yet but wouldn't think they would all blow at the same time.. (will do this next)..

Recently, I lost function of brake lights, turn signals, and hazard flashers. All happened at the same time. Some threads discuss flasher relays, short steering column wiring (position of steering wheel), and fuse failures.
I checked #18 fuse and a few others. All had continuity. I assumed my bulbs were all good. My hazard push-pull switch did not feel right. There didn't seem to be engagement. At this point, there was a good chance that the multi-function column switch had failed so I decided to try replacing it. I'm happy to report that this switch was the cause of all the light function failures and now, all is well again.
Removal is done by prying the key lock switch cover off,, removing three 1" Philips head screws that attach the lower column shield to the upper shield. At that point the upper shield can be completely removed. The lower shield was not totally removed because the tilt lever was left on. The switch is attached to the column with two 3/4" Torx 20 fasteners. The upper is easily accessible and the lower fastener can be removed by pulling the lower column shield down so access can be achieved. The two wiring harnesses have a conventional harness lock to depress and the connectors pull outward from the switch. Installation is the reverse of removal, noting the dowel locator and small plastic dowel on the lower shield.

My sons 2006 F350 brake lights and rear turn signals quit working. When the headlights are on, all the lights operate but the rear turn signals and brake lights do not nor do the emergency flashers. The front signals work but flash very rapidly. Although I'm not an auto electrician, I'm fairly mechanically inclined but the fact that the front signals work, the rear don't and all lights work as lights, just not as turn signals or brake lights.

Every time I step on the brakes, there is a bright spark in fuse #13. My brake lights, turn signals and hazards don't work. At this point my truck isn't drivable.
According to the owner's manual in my truck, says circuit #13 is for "stop lamps, CHMSL/hazard, trailer tow stop lamp, and speed control."
I'm assuming that the hazard part covers the turn signals as well, but I know the cruise control works even when the fuse is blown. I used it last night on the way home (this was before I realized I didn't have brake lights).
So I know I have a short somewhere. The only mods I've done to the lights are aftermarket headlights, but if the fuse only gets blown when I step on the brakes, I don't see what that would have to do with it. Also, the lights have been installed and working for about a month before this started. The only thing that I did around the same time was install the gauges. I ran the power to them from #5, the customer access circuit.
Are there any other "common" areas for this to happen? I already removed the rear brake lights and it didn't work. I am quickly running out of 20A mini fuses.

2013 F250 XL with factory towing package.
My camper and boat trailer do not have turning signal or brake lights when plugged into the round seven pin trailer connector. I have tried both the connector in the bed and under the bumper. I've also connected the trailers to other trucks and the lights work fine so I know the problem is in my truck.

I am a trucker at heart and I like to add running lights to my running board / step bars. As far as installation of the lights, done it several times, no problem there. However in the past, I have just ran a wire back to the trailer plug and used a scotch lock / snap connector to feed the running board lights.
If I do the same on a 2012, will that cause havick with the computer? Most likely I will be running 7 lights, all 3/4" diameter LED style. If this isn't' the best solution, then where to get power for marker lights.

I have a 2006 F350, it keeps blowing fuses for the brake/turn signals. The puzzling​ part is it only does this when the truck is running.

I'm having problems with my front marker lights. The turn signals work but when I turn on the parking lights or headlights they don't work. They only work with the turn signals. And I can't get the front side marker lights to come on. I've tried everything...

I just bought a 2001 F250 XLT and it came with the standard power paddle mirrors. I would love to add the towing mirrors (preferably heated with signals), but what I am wondering is if the connectors for the mirrors are the same. Also would my truck that came with the standard paddle mirrors be wired for turn signals and heated options? How would I test for this? Also do all XLT's come prewired for the hardwire keyless entry pad if they have keyless entry?

I would like to add an LED light to each running board and tie it in with the dome light wiring so that when the door(s) are opened it will come on with the dome light and light up the factory running board. Any info on where a good place to splice into the wiring, and will the wiring be able to handle a couple extra lights?
The truck is a 2012 F-350 XL, SD Dually....

I just bought my 2016 super duty about 2 months ago, really liking it, got a couple questions- How do I turn off daylight running lights? When head lights are on, instrument cluster lights come off and on according to outside light levels, can I turn off this feature?

No straight answers found yet. It's just the running lights that get stuck on.
I don't have auto lights, and after a period of a minute or 2 the lights pop off. There must be a relay sticking somewhere.
Looking for a diagram that shows where the relay for running lights is located?

My neighbors 02 250 6.8l the turn signal/hazard relay is clicking with key off, sounds exactly like a turn signal when truck is off and switches are not engaged. Here's the weird thing, if you hit the brakes the relay stops clicking, if you engage the turn signal or the hazards the lights on the dash are in time with the relay as it should be, but when the turn signal switch or hazards are turned off the relay keeps clicking except when you hit the brakes. Also the turn signal will work with ignition off, if you pull the relay out the turn signals and hazards are inoperable but the brake lights still work. I swapped in a new relay and same thing...
