Ford F-150 (2004-2008) :: Turn Signals Or Brake Lights Lost
Mar 7, 2011
I was using a 2004 Heritage F150 and when I connected a trailer to it something got fried. I lost both my turn signals and brake lights. The trailer worked fine on my friends truck so I don't think the issue was there but with the 4-pin round connector that was on the truck.
I found two 10A fuses blown under the hood and replaced them but that didn't work. They were in slots 19 and 20 and are listed as the camper/trailer adapter fuses. The running lights still work. The interior turn signal arrows don't even light up or anything when the turn signal is activated.

I have a 2006 F150 xlt 5.4 3v. I've owned it since Oct. 15'. In approximately Nov. I lost the rear right brake and blinker light, and then around Christmas I lost the rear left brake and blinker. I also have no rear hazards, but the inst cluster flashes at a normal rate when the flashers are engaged. All running lights work, and 3rd brake light works. Front blinkers work and all other electrical works. Have checked all fuses and bulbs with no solution.

I was turning left in my 01 Excursion and I think I hit the turn signal while doing so and tripped something. Now I have no turn signals and no brake lights. Headlights and tail lights work fine. I checked a couple of fuses under the hood that I believe are for turn signals, according to my manual they are fuses #20 and 22. They aren't getting any power, but the fuses themselves are fine. Is there another fuse somewhere to check? Or something else entirely?

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.

A friend of mine has a 2004 F150. The tail lights and the 3rd brake light are working but the rear brake lights, flasher and turn signals have stopped working. What could be wrong? I googled the problem and did find one person with the same issue in a 2001 F150. There apparently was a recall (#05S28) of the SCDS (Speed Control Deactivation Switch) but that vehicle kept blowing fuse 13. My friend checked his fuses and they were all ok,

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?

My 2007 F150's turn signals and hazard lights quit working. I checked the fuse and it was blown. Once I pulled the old fuse out the truck wouldn't start at all. What happened?

This has been driving nuts for 2 days.... Brake lights dont work. Either pushing pedal or turning on lights. Turn signals work just fine.
Cab/cargo/3rd brake light on back of cab doesn't work either. I have checked/done the following:
- Checked Brake pedal switch for continuity. Tested fine.
- put multi meter on wiring all the way back to brake lights. No drop in voltage.
- changed bulbs. #3157 dual filament.
- positioned steering wheel all the way up and all the way down as suggested on here. No change.
- checked multi function switch (turn signal switch) for wiring issues. None found.
- kicked rear quarter panel for caveman adjustment out of frustration. No change.
What am I missing?

I found out last night that all 3 of my brake lights are out. However, my tail lights work, and my turn-signals work. So obviously its not a big wiring deal. I was looking for the brake switch but i don't know where its at because i looked underneath. What fuse is the brake lights cause my manual doesn't have it listed. I drive a 04 Elantra GLS.

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.

The brake and turn signal lights on my 04 f150 quit working. I've replaced all of the fuses and relays I could find from the owners manual. The windows have also quite working. What may be wrong?

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.

I recently bought a 07 Expedition with light left front damage. After the repair I noticed that I'm not getting any power to the rear turn/brake, and backup lamps.The tail lamps and third break light work as does the trailer plug. I know that they were working prior to repairing the front. I did disconnect an aftermarket alarm during the repair. Basically all I replace was L/F sheet metal. Of cause I checked the obvious things like fuses and current to the tail light sockets.

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 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)..

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.
