Ford Wiring/Electrical :: 2010 - No Brake / High Mount Brake Light / Rear Turn Signals?
Apr 19, 2015
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.

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.

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?

I have a 1962 ford falcon ranchero. The driver side brake light, goes out when brake pressure is applied, but is on when lights are fully on, but even then brake pressure is applied and goes out. Right brake light is fine. And turn signal on right works. But driver side back light goes out when brake pressure is put on and when turn signal is put for left side. Right makes a turn noise left side doesn't. I recently replaced the turn signal switch. So its brand new. But older wires every where else. No cuts anywhere on wires. Fine. And replaced the bulb also.

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.

My wife's 2010 ES 350 third brake light has an intermittent LED issue. The last 3 LEDs on the pass side flash on/off when the brake is depressed. My understanding is there may be a broken solder joint. My problem is I can't seem to get the assembly out. How the high mount assembly is mounted and how to remove it?

85 f150. My driver side brake light and turn signal in the back quit working. The tail light works tho which is a different filament. The bulb is good and I changed the flasher relay...the circle thing in the fuse panel. Everything else works just fine. looking for a starting point.

I installed LED tail lights a few months ago, now all of a sudden the passenger side does not light for brakes or turn signals. The lights came with resistors that I put in when installing and the adhesive wore out and they were dangling in the truck frame. The wires connecting the resistors to the light were damaged. I taped the exposed wires and secured them a with a heavier tape, but taping did not work. I also tried switching the resistor packs with the driver side to see if it was them that have an open winding, but they are still operable.
I narrowed it down to wiring between the trailer hook up and passenger light assembly in the electrical circuit. I plugged an LED light bar into the trailer connection and the same problem occurred (running lights come on, but no turn signal or brake light). Where could there be a short? Or is this circuit fused somewhere that the running lights come on but a separate fused circuit triggers the higher voltage for LEDs.

Need a wire diagram. I have a connector in the cab that has red,blue,lt green,white wires. It's causing my brake lights not to work. I need a wire diagram that shows were they go. I can't find these wires in my Haynes manual.

My Ranger, an '04 Edge without cargo lights. The high mount stoplight is faintly lit with the parking/headlights on. I had changed out the incandescent bulb for a LED, and went out to see how everything looked after dark. Well, the high mount had a slight glow to it, not really on, just a faint glow. This was never noticed with the regular bulb. I suspect I may have some stray voltage coming from somewhere, just enough to make the LED glow, but not enough for the normal bulb. When I switched off all the lights, it went out as well.
I tried to find a wiring diagram on line, like I've suggested to others in the past, but no luck from Autozone, or the EBSCO host I've used before. In fact the EBSCO will no longer accept "tech" as a user name or password.
So, where the problem may lie? I hate it when I can't figure out something like this!!!

So I recently bought a 1997 7.3l F250. It is in fairly good condition, but it has some problems with the lights working. The turn signals and hazards all work, as do the tail lights and headlights. However, when I hit the high beam switch, the headlights cut off entirely. Also, the brake lights do not work at all. Ive checked the bulbs and since they all work Im not sure what the issue is.

Trying to replace the burnt bulbs. Did the obvious: removed the two screws but in no way could I take the red lens off. I pried hard almost broke it but it's not coming off. It feels like some other mechanism holding it down. It is the one on top of the lift gate. The inside is just a hole with wires going through. What's the trick?

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 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.

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?

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.

Can this be changed easily by a non-dealer? The local Autozone doesn't list any replacement bulbs or assemblies, and I can't see a simple way of accessing the light assembly from the trunk.

My turn signals will not work with the engine running. With the engine off they will. With the engine running if I move the ignition like I am going to turn it off they work.. Is it the ignition switch or ign cylinder....

I must be missing something here. Where is the flasher for the turn signals? It isn't the two relays behind the radio is it?
