Ford Wiring/Electrical :: 1973 F250 - No Turn Signals / Brake Lights Or Rear Hazards
Aug 25, 2010
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.

So I have an 04 F250 Super Duty 6.0L and suddenly the turn signals and hazards stopped working. First I replaced the switch on the steering column...no luck. Today I replaced the flasher relay under the dash panel (the blue one)...still no luck. I remember checking fuses in the fuse box but don't remember which ones I checked but I didn't see anything obvious. I also took a quick look under the dash at all the wires for any anomalies...nothing. I'm lost... What to do next!?

1991 F250 Supercab Diesel 4X4. I made a mistake while wiring up my trailer lights and ended up grounding out my brake controller, frying it. Along with that, I popped a couple fuses as well (1, 5 and 9 I believe). Replaced all fuses and got my signals (F/R) back at least.
Here's what's NOT working/messed up:
*Brake Lights
*Cruise Control
*Rear ABS light comes on a few minutes after driving.
*Front hazards work, not rear. When I apply the brake, the hazards pause in the on position.
I've tested the brake switch on the brake pedal (Green/Red and Green) and it works properly. So, current is obviously not reaching the rear brake lights.
Another note. The truck is wired with a 7 pin plug in the bed for a goose neck trailer. It also was wired to a 6 pin on the bumper. I replaced the 6 pin with a 7. The signal/brake pins on the plugs (both) and also not receiving power. What's the next thing to check?

2010 F-250 14,000 miles, gas engine with Knapheide utility bed. Tilt wheel has been kept in the up position from day 1.
The problem:
No rear brake lights.
No high mount brake light.
No rear turn signals.
No rear hazard flashing lights.
All trailer lights work.
All other truck lights work.
Things checked: Fuses all OK. Visual inspection of multi-function switch. Looks clean. Brake switch at brake pedal has power on one wire. Jumpered the other wire-no brake lights.
I need to haul my trailer and am nervous when I see a Savannah, GA metro police car.

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?

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.

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.

I'm working on the '73 F250 in my sig. I'm not very skilled when it comes to electrical work and I don't want to hack things. First up is I'm wiring a 7-way trailer connector with brakes. I need to tap into the brake light switch at the pedal, what is the cleanest way to do this? I was thinking of sticking a blade connector in the existing connector or adding a plug pigtail.
Also in the future I will (hopefully) be doing a 3G alternator swap and adding relays to keep my headlights from shutting off. I'm looking for suggestions on a junkyard or aftermarket fuse block that will accommodate the circuit breaker for the trailer brake, the 100 amp fuse for the 3g swap and the relays for the headlights.

I 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.

I 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?

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?

First 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.

I have a unique problem with my newly acquired 71 F250. The left brake does illuminate when the brake is pressed but when the right turn signal if activated the left brake light does come on. The left flasher light also does not work. All other rear ligh function are normal. I am assuming I have a short or a wiring issue just wanted to know if there was any common item that might be know about this topic. The bulbs are all new. The reverse lights do not work either but pretty for sure its unrelated.

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.
