Ford 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.
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) :: Trailer Light Replacement Harness
The pigtail from my bumper mounted 7-pin to the factory connector is all hacked up from the previous owner so I'm looking to replace that pigtail. Also wondering if there should be 2 connectors down there to add a connector for my gooseneck or do I need to splice another universal 7-pin into the bumper light pigtail? Also, is there another (preferably slightly cheaper) option besides e-trailer for such a connector?

03 f350 7.3L. Have no power for the trailer running lights at the connector end. No power when the end is split and no power at the next connector above the spare tire. I have power at the fuse (38) and the fuse is good. What is the best connection to check next? Is there a common culprit that might cause this problem somewhere? I know 3 more connectors are in the frame by the fuel tank but pretty much lose track of which one might have the wire for the trailer.

Have a 2008 F-450 that I just got and the trailer light outlet does not work. There is constant power to one pin and nothing on the tail/turn/stop pins. I have checked all of the fuses and relays and they seem to been fine. And yes, I did a search and did not come up with anything.

My husband and I bought a 09 f-250 with 58000 miles. It used to pull our travel trailer with no power issues. Now the rpms go up & the power goes down. It never gets hot nor any lights come on. It's been in the shop twice. The first time nothing was found. The second time we were told it was dirty fuel filters. The truck only has 70k miles...

I have a question about my new to me 2006 F-250 CC, 4x4. Resource the 12-volt accessory supply wire that goes to pin #4 on the 7 pin trailer connector? We have interior lights in our enclosed race trailer and it's a bit of a pain to have to turn the key on to use the lights. Just don't want to run a direct fused wire from the battery to the plug if I don't have to.

I use a bottle hanging like an I.V. drip to flush the Brake Fluid in all my cars. I can pump all the old fluid out, as well as the air. My Superduty 7.3 has a good solid brake pedal after the flush. It seems to me the rear brakes handle 60% of the stopping load. Its been like this for so long I'm not sure if it's ever been different. i then go to a gravel or wet road and test the rear abs, and it seems o work, but definitely has a squirrely feel. I did some strong pavement stops with speed, and it stops, no skidding. Is that the way it should be?

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) :: OEM 7 Way Trailer Connector Broken Off?
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.

Ford Super Duty (1999-2016) :: Trailer Plugs Do Not Work
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) :: 2003 F250 - Surge / Lag When Shifting
I just got 03 f250 with 6.0 and when shifting has a weird surge/lag thing happening. Reminds me a little of the old 7.3 surge when it was just started on a cold day. Seems to be worse in higher gears.

I've got a 99 f250 5.4 that runs like a top. In the last 6 months I've been chasing a little problem. It doesn't happen all the time but seem to be happen more and more. While driving any speed If I let off the gas the RPM's hold at around 1500 then surges down to 1000 then back up again to 1500.
Does that 2 to 4 times then all good. Give it gas again it does it again. It kind of does it when it wants. Could be fine for a trip around then next trip it acts up again. Checked a lot of the vacuum lines, PVC valve and replaced the idle control next to the EGR valve. EGR is next.
Idles and runs fine except the surge thing..
P0401 code as well.
Ford Super Duty (1999-2016) :: F350 - Engine Surge / Crashed?
I was recently involved in a fender bender. As I backed out of a parking space, I struck another vehicle. When I immediately attempted to pull back into the parking space to check things out, the engine in the F350 bus surged to the point that it crashed into one of the safety poles in the parking lot despite the fact that I had both feet on the brake pedal. The vehicle is 8 years old and has 25K miles (not used frequently) but never had this issue before. Could the crash have something to do with the vehicle's computer and the subsequent surge?

I have a 2002 f350 Super duty, 7.3. After I changed out the power steering box, I did bleed the system, I have now power steering and the brakes are very spongy. Any thing to check prior to replacing the booster? I have been told the power steering is probably just an alignment issue and I should bleed the brakes.
