2008 F 550 6.4L Diesel 2wd... Truck has a few interior elect systems not working. ALL fuses are good. 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 RepliesI 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 2 RepliesTroubleshooting a problem with friend's 2000 F250. His power windows aren't working and are causing problems with his door locks and interior lights. When he tries to use his drivers side power window, his power door locks quit working. If he puts the switch to raise, the interior lights flash. From what I've read, it sounds like the GEM to me, we've inspected the wiring and it all looks good. I pulled it out today and it looks good inside, no sign of water leaks on it. If it is the gem, how much do they cost and do they require programming?
View 5 RepliesI have a 2006 F250 6.0L Crew Cab 4x4 that started acting up. It started two days ago when I noticed my windshield wipers were only working at one speed. Then today my wife took the truck to work and she said the radio stopped working on her way to work. Then she gets in this afternoon and the ABS light is on, the A/C isn't working, the windows are super slow and the interior lights are flickering. She isn't home yet so I haven't checked the fuse block. Where would you start looking?
View 3 RepliesI have a 2012 F250 and am having a problem where the interior lights wont come on with the dash switch or when the doors are opened. I have confirmed that it is not a bad fuse, also the lights will come on when the switch on the individual lights is manually pushed, but not automatically like they are supposed to. I dont see it being a door switch issue because the door chime comes on and the stereo goes off when the doors are opened after turning the ignition switch off. I've read that the dealerships will switch out the BCM. I thought maybe the dimmer switch next to the headlight switch but there is no power to it whatsoever, which also I can't dim the instrument panel lights. What did you do to resolve?
View 1 RepliesJust got a 2001 F-250 Super Duty (crew cab, long bed, 4x4, 7.3L turbo diesel) and have been going through and fixing a lot of little issues. The one that now has me stumped is the interior lighting circuit (which is also the bed light). Here's what I've got so far:
Map/reading lights work, but dome lights do not (neither automatically nor when turning them on via the dimmer switch). Verified all fuses in the PDC as well as the interior fuse panel (behind the driver side knee panel). The interior lighting relay was missing, so I purchased and installed it.
Relay #1 (interior lighting), fuse #4, and fuse #14 are all good - when I pull the fuse with the door open, the relay clicks (and clicks again upon reinstalling the fuse). With the doors closed, the relay clicks when activating the interior lights via the dimmer switch.
The LT GRN/YEL wire is hot, and all related accessories work (map lights, engine bay light, etc).
The BLK/LT BLU wire is not receiving power from the relay from what I can tell.
Before I start trying to pull out the fuse panel to start checking connectivity, anything else to check? The ground at the rear driver corner of the cab is good, and a visual check of the harness running down the driver side of the cab has no visible signs of damage.
Also, given that the relay is audibly actuating the way it should, I'm guessing that the GEM can be ruled out as a possible cause? My next step will be to get a pinout diagram for the relay and crimp a quick jumper to see whether or not it's simply a defective relay... But I doubt it's the case.
Two nights ago I got into the truck at night and realized the interior lights don't come on. I tried the rocker switch it will only dim the dash gauges now. It did work before guessing its a bad rocker switch. I can turn them on manually front and back....
View 5 RepliesOk, 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 9 RepliesI'm working on a 2000 7.3 that was running but had no power so we changed out all the injectors and glow plugs and rebuilt the turbo now there is no start ...
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?
New to me 2012 F550 parking lights will not go off. Battery disconnected now. Touch battery cable parking lights come on.
View 14 RepliesI 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.
View 3 RepliesI bought a new Motorcraft door latch for my F550 because the door latch won't stay latched. You close the door firm and it seats well then pops loose the first bump in the road. I found all kinds of OEM replacment latches all over the internet but nowhere can I find any instructions or videos or any talk of the best way to go about replacing the door latch. I know they wear out from constant use on the drivers side.
View 2 RepliesI am looking for the location of the fuel pump relay for my 1999 Ford F550 V10 4WD Gas truck.
I have replaced the fuel filter and fuel pump. When the key is turned the pump gets juice and 2 seconds later is not getting juice. No lines are coming into it, so it's not getting up to pressure and shutting off.
