I am trying to figure out where the relay would be when i look online for the map of the relay box under the hood it says nothing of a horn relay. I don't have a key fob for the doors to unlock so I wouldn't think its tied to the computer. Should mention nothing happens when you hit the horn also fuse is fine. No power at the actual horn when i hit the steering wheel(horn)....

View 14 Replies I was driving my truck and my power windows quite working I figured it was a fuse so I wasn't to excited about it I stopped and unloaded some scrap metal and then when I started my truck back up I couldn't shift it out of park unless I unplugged the brake pedal sensor or turned the key just out of the off position then shifted to neutral then started then I could put it in gear and go so I got home and started looking checked all my fuses all good then I realize the windshield wipers are not working either and the door beeper, if you have your keys in the ignition also isn't working the horn, isn't working the lights on the window and lock switches isn't working either so I'm kinda lost now gonna barrow a relay tester in the am but I'm kinda thinking maybe the computer ?? For all this to happen at one to,e doesn't make any sense to me that's a lot to all go in one shot it makes more sense to me
No horn
No power windows
No accessory lights on the window and lock switches
No wipers
No buzzer/beeper (like when you open the door and leave the keys in the ignition
Won't shift out of park without doing it with the engine off or the brake pedal position sensor unplugged
I've gone thru with a test light and got power to the fuses for everything but still nothing
I'm having trouble with my '99 F-350 7.3L 4X4. One day, my power windows, cruise, dome light, horn, wipers, and 4 wheel drive stopped working. After checking all of the fuses, I have found no bad ones.

Message center not working at all, HVAC fan not working, key/lights chime not working, and radio lights very dim. All of these problems started at once. Everything else on truck works fine.
View 2 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.

View 2 RepliesI have a 2001 F-250 SD XLT with the ABS light on, cruise control doesnt work and the horn only works with the key out. The codes for the ABS is no signal input from the left and right front wheel sensors. No problem there. Also my speedo stops or jumps when I press the horn button while driving down the road. When I quit pressing the horn button the speedo works fine. So after looking over the posts on cruise control, etc. Does the rear speed sensor have anything to do with the cruise, horn not working? All fuses are good so I am thinking the cruise control switch on the master cylinder or a short in the steering wheel column or my ignition switch. What do you all think?
View 7 RepliesI have a 'new-to-me' Ford F-550 with the vaunted 7.3 Powerstroke diesel engine. The truck only has 120k miles and ran great when I bought it. Last week it began acting up. While driving on the highway, it lost power, began running rough, and once I pulled over, it died.
After a few minutes, I tried re-starting the truck, it started, but had little to no power....I could get up to 30-35mph and then it would slow down and lost all power. I let the truck sit for about 20 minutes while I refilled the diesel tank, it started right up and drove normally for another 10-15 minutes and then the same thing happened again.
The truck sat for a day and then drove normally for two entire days. This morning, it began acting up. It is the same as before..... what to do with this type of issue?
There is not a check engine light lit (yes, it works). The diesel is from a good source that is not causing problems in anything else. The truck is otherwise strong.
Attempting to debug the Horn not working on my 2003 Ford F450, The fuse is good (shown as #37 15 amps) so next I would like to check the Horn relay.
View 5 Replies2003 f550 with 7.3, suddenly loses power and struggles while driving. White/blue smoke comes from tailpipe, can smell the diesel exhaust bad when happens, comes and goes intermittently but has been happening more and more often. I uploaded a video onto YouTube to show sound, rough running motor and smoke from exhaust although smoke not that bad in video. Search "shadetreelandscaping" on YouTube in case link below doesn't work.

Took to ford dealer a few diff times for problem and they can't get any codes, can't duplicate problem. After it being in for third time they say had to call ford tech hotline and they suggest replacing injector however can not and will not gaurntee that will solve problem, and obviously dealer isn't cheap for repair. I find it hard to believe that a bad injector(s) would be an intermittent problem as it is or that it would cause fuel pump to make gurgling sound.
Ok, so I am trying to get are 99 F550 all fixed up and have a few things to ask.
So we have had the ABS light on now for some time. I had it scanned at O Riley's and the scanner said the abs sensor on the passenger side was faulty. So I replaced that and the light was still on. We had taken the truck to ford to get it checked out for a rear end problem we have been having as some of you may know from a previous post I made.
Well ford said it was the rear sensor on the axle that was causing the abs light to come on. So I replaced that. Still have the abs light on. I disconnected the batteries to try and see if that would reset it and it did not. I hooked up the Scan Gauge II and ran to see if it picked up anything. It said it did not pick up any thing. I still did a code clear but it didn't work. If there a tricky way that you have to get the code cleared off?
2nd I was checking the fluid. I noticed that the tranny fluid is over filled quite a bit. Will this hurt it? Should I drain the fluid to where its at the fill line?
OK, so I have the brake pedal downshifting, but there is no real exhaust brake. Can I have one installed, like the latter model 2015 or even the 2016, with the button?

View 2 RepliesIt has a 7.3 bone stock in it. When it is cranking you can hear a relay clicking. it's behind the dash just below the radio. There are 3 relays together 1 big one which is for trailer lights and 2 small ones which i don't know where they go. but i replaced all 3 and i still hear the clicking ONLY when the engine is cranking.
View 1 RepliesI have a new 2013 F-550 Lariat 200" WB on order. I can and will increase the combination weight on the truck, to make full use of the 19, 500 gvwr. My question is how much will a current F-550 pull on a 5th wheel/gooseneck style trailer before it becomes dangerous? I plan to set the truck up with an 11ft aluminum Eby flat body, with a Holland FW6000 5th wheel placed under the body. I am considering a 35 or 40 ft flat gooseneck.
The combination weight would be changed based upon the axles I choose to put under the trailer. Two 12k axles will give me 44,000 gcwr, two 15k axles will give me 50,000 gcwr, and two 16k axles would give me a 51,000 gcwr. The truck will be able to carry about 10,000-11,000, the trailer needs to take the rest. I am confident that 44,000 gcwr will not be a problem, but the idea of 50,000, or 51,000 really makes me question safety. So, how much have you hauled with a F-550, and a gooseneck trailer?
I have a 2001 F550 flatbed tow truck with a 7.3 and the ZF 6 trans. i put a Luk clutch flywheel pressure plate new throw out bearing new clutch fork New clutch slave cylinder and master set up. When i push the clutch in it is VERY EASY compared to the way it was before. Ane when you push the clutch in and put it in gear you can hear the clutch disc rubbing on the flywheel and if you lift your foot the thickness of a hair the truck takes off. Also i can't engage my PTO because the clutch is not disengaging all the way. there is No adjustments on this set up. What Now.
View 2 RepliesI have a 1999 Ford F550 with a 6.8L V10 and a 4R100 Auto.
I want to run an underhood hydraulic pump, like what a wrecker uses only I want to use it to run a generator under the truck.
How can I get a 6.8 to idle up to 1200 or so? I searched the Body builders guide and it looks as if the idle up is for the 7.3 only.
My truck also is not a 2005 and up like the other posters, who can take advantage of a drive by wire.
Also I doubt my transmission has a PTO cover so I think a generator option using that route is a dead end. What are my options to idle the truck up to 1200?
I have a new to me 1999 f550 w/ 7.3 and I have installed an aluminum service body with a crane on the passenger side bins. The crane itself weights about 650lbs plus the steel frame it is mounted on (superstructure in the aluminum service body). I'm concerned about the uneven load on the rear suspension. It does sag slightly to the passenger side - guessing 1" - I will measure tomorrow.
1) Should I be concerned?
2) What can I do to correct it? (without just adding weight to counter balance it).
Really love my 2013 F550 but the door chime is driving me crazy. On my 2003 f150 you could just drop the column cover and unhook one wire running to the tumbler. So I had a look and found it to be totally different. How to unhook it on this truck?
View 2 RepliesRecently removed a plow and wiring harness from my 00 F550 and now my headlights no longer work. The headlight plugs have an adapter that the plow harness plugged in to and it now appears I need some type of end plug on each one to complete the circuit. The problem is the dealer doesn't understand what I need and doesn't think there is such a part out there. Perhaps my thinking is all wrong.
