Ford Super Duty (1999-2016) :: Fuse 13 Keeps Blowing - Brake Lights / Turn Signals And Hazards Don't Work
Feb 25, 2015
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.

2000 V10 F250 - daughter is using my truck and called to tell me the turn signals weren't working. She called me shortly after and said she adjusted the tilt and hazard lights came on and now she can't turn them off. I had her pull the hazard fuse to stop them. She then noticed the brake light weren't working. I don't know if the brake lights were because she pulled the fuse or she just noticed they weren't working.
A week or two ago, she said she parked the truck, turned it off and took the keys. When she came back out, the truck had rolled across the street. Periodically, over the years, I would go to start the truck and nothing happened. I would shift the gear selector in and out of drive. Then the truck started.
Finally, since I've owned the truck, the when I activated the left turn signal, the selector frequently wouldn't stay "locked" till I turned. So, are these related? Do I have multiple issues going on in the steering column. Where to start looking when she gets the truck home?

I have a 1995 Ford f250 Powerstroke and i do not have turn signals, rear running lights, brake lights or reverse lights. i checked the fuses and they seem to be good but i dont want to tear everything out to check the harness if it could be a bad ground. any insight?

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.

I have checked all fuses, checked wires on top of steering column all checked out ok. Hazards work but when I press brake tail lights just blink with no brake light but the 3rd brake light works??? Signal switch maybe??

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 have 1999 ford f250 superduty 5.4 v8 I noticed that my tail lights were not working I replaced the fuse as it was blown break lights worked until i cranked up and applied brakes. I replaced fuse again an checked brake lights they worked fine until i cranked truck and applied the brakes i did notice the wires were hot at brake pedal switch when they worked while not cranked. I replaced the cruise control release switch I was told that may be the problem since cruise didn't work. it fixed the cruise control but as soon as i pressed the brakes fuse blew again.I replaced brake pedal switch didnt fix it.
I then noticed a little smoke under tailgate i looked and the wire coming out of connector was hot while brakes applied and not cranked. i disconnected that wire put a new fuse in and brake lights worked in center light and passenger side without blowing fuse driver side however does not work. Because I disconnected the brake light wire to driver side green wire. When I reconnected the driver side brake light wire fuse blew.
So I have it narrowed down to driver side brake light. here is my problem. I have checked all the wires that i can see for bad or frayed /worn naked places i have found none I can get to the wires beside gas tank running the rail to check but it is doubtful that it is spot as nothing is rubbing along there. Could it be a relay somewhere? can i just run a new wire from brake light? if so where to i connect to? Is there a wiring harness i can just buy and replace the brake light wires from brake light to power source I have ran out of things to check on my own...

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 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)..

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?

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.

I just got a 2000 F350 cc drw 7.3l.
I did search but have had no luck. My turn signals do not work, unless my foot is on the brake pedal my green arrow indicator wont even turn on. When they do my bulbs work but don't cycle so I know all the bulbs are good as I had my wife check all four corners when I got them to come on for a split second. I have tried replacing the MFS and the turn signal relay under the radio in the dash.... When I do turn on my blinkers I can hear the relay click once but that is it, no more.
I tried checking the wiring in the column and tilting the column to its extremes while trying to engage the turn signals. Also, if I unplug the brake light switch then I do not get an arrow on the IC to light up so I am guessing the power flows through that switch. I don't have a chilton manual yet and the owners manual was not in the truck. I did check fuse 23 ?

Well, on our way home during my leave, the wife made the comment about halfway home that the blinkers had quit working. I assumed it was probably a fuse or relay, so we came on home. I have been looking at it for a few days now (too hot to spend too much time out crawling around under the dash ) and I am still having some trouble. My brake lights, and hazards are not working, and neither is the cruise, which was working fine while I drove before the blinkers went out.
I have no power at all to the flasher relay. I replaced the brake light switch because it was definitely worn and looked a little burned inside when I pulled it out and inspected, but still nothing. Have not found any fuses blown. Brake pressure switch fused link harness seems good with my test light. Wipers, brights, everything else on the turn signal switch works fine. Can't even get the cruise to go into diagnostic mode, it only blinks once when I try.

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.
