Not working at plug.

Ford Super Duty (1999-2016) :: Trailer Brakes Quit Working?
This past weekend I loaded up my 3 horses on my trailer and found out going down a hill that my trailer brakes aren't coming on and tracked this down to a problem with the truck. Need to troubleshoot this before taking it to a dealer to check wiring problems for shorts somewhere.
What doesn't work: trailer brakes not getting any power to the brakes. When I first pulled out the truck had error message popping up saying Trailer wiring fault and once in a while that would disappear then come back on and once or twice went to Trailer disconnected. My friends hooked up my trailer to their truck and the brakes worked on the trailer.
What's working: turn signals and brake lights coming on in the trailer.
What we checked so far: fuses, sprayed truck plug with wd40 on the pins. The brake pedal not activating the brakes and tried just the slider bar on the ford integrated brake control box.
Background: brakes were working fine back in October. December hauled them a short distance and didn't notice any braking problem but road was mainly flat and when coming down a small grade they seemed fine but I was going slow also. Back in January, I took the truck to a Firestone to get general maintenance work done on it including truck brakes checked for wear and tear and they had to replace the truck battery.
Where does the truck ground wire go to in the truck to ground it out? All that I can find is that it has to go to some pure metal, no painted surface but can't find anywhere on where to check this out on the truck to see if it is still making contact. Could the guys at Firestone have not hooked something back up or knocked it. The last thing that I would like to look at before getting the wires all tested. I have a 2008 F250, gas
Ford Super Duty (1999-2016) :: No Right Turn Signal On Factory Trailer Harness
I'm still fighting tow harness problems on my '01 F 250. I started by replacing the 7-way pig tail with a new one which didn't work. Then I undid all the butchering of the harness that was done previously. The factory harness had scotch locks all over it that were used to splice in a 6-way and a 7-way into the bed. I liquid taped all the nicks in the wires. Then I checked for power at the factory harness end where the pigtail plugs in. I have park/running lights, and one of the ports flashes for the left turn signal/flashers/stop lamps. I got rained on before I could check further up the wire. If I have no power to the wire further up is there another place to check?

- Are there any relays that control the truck brake lights and the trailer brake lights ?
- If yes where are the brake relays exactly?
- Have I missed or not done something else to correct the problem?
Ford Super Duty (1999-2016) :: Trailer Has Running Lights But No Turn Signal Or Brake Lights
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 replaced the bulb and it's still not blinking and doing the quick blink on the front and mirror bulbs.
The bulb turns on when on parking lights; it just won't blink.
Ford Super Duty (1999-2016) :: How To Know Trailer Connected
How does the truck know that there is a trailer connected?
With my cab-over camper and no trailer as soon as I go to reverse the back up alarm goes off. I thought I would wire in a marker light to the trailer brake circuit but that didn't do it, maybe not enough resistance? The truck still says no trailer.
How I can fool the system so that when I load the camper it looks like a trailer to the truck?
Ford Super Duty (1999-2016) :: F250 - Front Turn Signals Not Working
1999 F250 super duty. I am having a problem with the front right turn signal not working. The indicator on the dash also does not work but I can hear the relay clicking double time and the rear signal works. I have changed the bulb and fuses and went under the dash and the column to be sure a connection had not come loose. I have looked through the forums to try and find an answer with no luck. What to try next?

I've done a bunch of searches and can't really find much. The turn signal in my 03 SD doesn't work, and the back side is loose, probably a broken tab. I have cranked the mirror up, down, right and left, popped the tabs loose yet it feels like I'm missing one or a screw. I read that I may have to "Pop" my mirror off to get to stuff. The dealer said I have to buy a complete mirror assembly just to change a freaking bulb on an 03?

Well, it seems the cover on my trailer connector got broken off. The cover locks the trailer plug into the truck side. The connector on the truck is/was supplied by Ford. Now the dealer say NLA, only 2005 and up. Truck is 99 F250 SD. Plug is 4/7 way. Where can I locate a direct plug-in replacement? I do not want to be cutting and splicing.

Went to hook up my trailer today and both the trailer plugs do not work. I checked the fuses and all is well. They worked fine the other day but now they don't work at all. I confirmed this by hooking up to another trailer and nothing. Also got another truck and went to trailers and it worked.
My truck has 19000 miles so it's practically new. I have never seen this. I called dealer but they can't see it til next week and I need the trailer brakes and lights. Where could I look or what could the problem be?
Ford Super Duty (1999-2016) :: F350 - Turn Signals Stopped Working Suddenly
I own a 1999 F350 CC SRW w/ 7.3L PSD engine. My turn signals stopped working suddenly. I've checked the fuse panel under the dash but it doesn't show any fuse for the turn signals.
My hazards do work although I noticed something very strange. When I tilt the steering column down the hazards stop working and when I tilt the column all the way up they work again. Still no turn signals though.
Ford Super Duty (1999-2016) :: ESOF 4WD Not Working / Turn The Knob To 4 Hi Or Lo And No Relay Click
I have a 2001 for f250 with the electronic shift on the fly and when I turn the switch to put it in 4hi or low nothing happens I don't hear a click and the lights don't come on but the 4wd light works it comes on when I first start the truck and I put different relays in that we're good and still nothing I tested the the relay box itself for power and there wasn't any.
I used the truck last year for plowing and it worked sometimes it wouldn't go In or come out but after a few tries it would end up working but I've tried everything I could think of I'm starting to think it's something electrical because the relay box isn't getting power to it but idk if a vacuum leak would do that or a bad transfer case motor or iwe solenoid or if it's something more like a broken wire some where.
Ford Super Duty (1999-2016) :: 2002 F250 - Turn Signals Quit Working
I have a 2002 F250, 5.4 extended cab 4x4. Factory lights. I have no turn signals. They were working just fine and without turning off the truck, all 4 corners quit working at the same time, as far as I know. The indicator lights on the instrument cluster don't work. I have checked/replaced all fuses. Replaced the switch lever and the blinker relay behind the dash. The hazards do work and always have. It might be coincidence but I believe the back-up lights quit working at the same time.

So the other weekend I hooked up to my buddys landscaping trailer, everything was fine until I plugged in the harness, No Lights...no big deal cuz it wasn't much of a drive, but I gotta haul a boat tomorrow a little ways and Id like to be legal.
I need cleaning my trailer plugs. What is the best way to clean the terminals on the small 4 prong? The big plug is fine, just a little dirt inside the cover, but I am still going to clean the contacts and put di-electric grease on them.

View 14 RepliesFord Super Duty (1999-2016) :: No Power To Trailer Light Bulb?
A week ago last Saturday I bought a 2006 F250 Lariat Crew Cab with the 6.0 and 4WD. The truck is really clean and only has 68,000 miles on it. Here's my question: I needed to tow a boat today and I discovered I have no power, at all, at the trailer light plug receptacle. Nothing at the 7-pin nor the flat-4. I looked through the manual and checked every fuse that had the word trailer associated with it and I can also feel the turn signal relays clicking with the flashers on.
Am I missing something really simple or do I just need to follow the wire harness from the back and look for something that is not connected? It seems kind of weird for it to be just....dead.
