I replaced all the exterior bulbs in my 2013 F250 6.7L with LED bulbs. My trailer lights work but brake and signals don't work on the trailer.
View 5 RepliesMy 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.
View 4 RepliesEvery 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.
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.
View 6 RepliesWent 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?
I was adding some more running lights today and tried to tie in to the front running/turn signal light. Next thing I know I hear a pop and now no turn signals, hazards or brake lights on my 99 F250 SD V10. My 3rd (center) brake light does work though when I press the brake, it's just the tail brake lights that dont work.
I can't find a blown fuse for the turn signals or brake lights (not really sure which fuse box it's in since the manual doesn't tell me what fuse is what)
I however did find what I'm guessing are the flashers behind the radio. What might have went wrong where before I start dumping money in to flashers and relays.
The next question is, can I jump in to the marker/turn signals and add another single LED light to them off the front? If I can which color wire does what?
I have an 05 f350. I cannot get trailer running lights to work. All other lights work. Trailer brakes work, battery charge for dump trailer. I've checked fuses under dash and under hood. Everything checks out. I'm Stumped.
View 6 RepliesWas checking fuses for why my 3rd brake light and pedal adjustment switch does not work. Was also looking for a fuse to tie into so that a light in the cab floorboard will stay on when the headlights or marker lights are on... After trying several spots to no avail (finally putting it into the bright headlight fuse). I got the light to work.... But now my ABS light stays on!!! Also 3rd brake still not working...
View 1 RepliesI've just bought a new 2016 SD xlt. The only extra I wanted that is missing is the factory trailer brake controller. The dealer told me it had to be programmed. I was expecting plug and play and planned to do it myself till they told me that. Is this true?

View 8 RepliesI'm having problems with my front marker lights. The turn signals work but when I turn on the parking lights or headlights they don't work. They only work with the turn signals. And I can't get the front side marker lights to come on. I've tried everything...
View 2 Replies2000 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?
Where I can find a good used or a good deal on a new factory trailer brake controller to fit a 2006 F250 Diesel Truck?
View 1 RepliesI have an 08 F450 equipped with Ford integrated trailer brake controller. I tow between 6,000# and 14,000# machinery on a daily basis. I know the gain can be adjusted up to ten. I have noticed while braking "normal" The controller only outputs 1 green bar of power. Manually, the brakes on all my trailers don't grab untill around 3 bars of output. I find myself always sliding the manual lever to relieve the truck. The truck is suffering. I have the gain set to 10 just to get minimal result from the 1 bar output. I know my trailer brakes rock, they can stop the truck and trailer if needed. Can it be adjusted? How many bars are you folks getting with easy braking?
View 6 RepliesChecking out my 2007 gasser this weekend an found that my third brake light does not work....no power to the socket. The cargo lights on either side of it in the same assembly work fine so I believe the ground to be intact. My question is does this light have it's own fuse? if not where should I start looking for the solution to my problem?
View 1 RepliesI tow a 5th wheel with my 2014 F-250 that has an factory TBC. I just installed Electric over Hydraulic disc brakes on my 5th wheel and was trying to see if there was a setting I needed to change on the TBC to tell it that is now E/H versus E. In the Information section of the dashboard display it talks about the controller actuating electric drum brakes but the manual talks about it being able to do electric AND E/H. What I need to do here...if anything?
View 6 Replies2010 F250 Lariat, cab and a half, PSD. 5600 miles.
Sunday I started the pickup and received "trailer brake module fault" in the message center. I wasn't pulling so wasn't too concerned - hit the reset and continued on.
Sunday night I started the pickup again and received the same message followed by "check brake system". I also lost illuminated gear selection, the traction control active symbol was displayed and the traction control "off" (PB) was illuminated. After several attempts it reset, everything returned to normal and I was able to get home without incident.
Monday morning it wouldn't start. It indicated "trailer brake module fault", "check brake system", traction control active and off, no gear indication, the odometer indicated "-------" and it did not react to the key in the start position.
Tuesday morning I attempted to start and it was the same as the previous attempt. I noticed that the theft prevention appeared active (flashing) so I removed the key, locked the doors, unlocked the doors, tried again - no joy.
I kept trying while holding my mouth in different positions and finally by the grace of God it fired. I delivered it to the dealer.
The dealer called yesterday afternoon and reported that everything is a result of a bad trailer brake module. The new one is to arrive today, they will install and everything will be peachy.
I asked if they could just unplug it and reprogram the truck to believe it never had one - the service writer said it can't be done, different piece parts on trucks with or without trailer brakes.
I really have no choice but to push the "I believe" button and carry on but I am slightly concerned. The fact that the trailer brake module can cause catastrophic failure doesn't seem too cool, I don't have a real warm and fuzzy feeling associated with venturing far from pavement, reliable communication or alternative transportation.
In the meantime I suggest that no one take "trailer brake module failure" lightly.
I have now found a chit load of LED fog bulbs in my search. I don't want to change out the entire light, just the bulbs. How do the bulbs effect the side vision. Almost hit a deer a couple of nights ago with my F350.....don't want that

View 4 RepliesWe bought a 2012 f550 chassis and had a utility bed outfited. As far as I know the truck does not have a tow package (major F-up). They did install a receiver and electric in the rear. The 7 way pin in the rear does have the appropriate wires (including blue). I can not find the harness in the cab under the dash. I have looked near the radio where I have found the harness on our other trucks. I specifically looked for the red white and blue wire under there. Where is this harness? Is the harness still in the cab even without the tow package? This will be for the old school plug in controller, not the ford intergrated contoller.

- 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?
