Ford Super Duty (1999-2016) :: F250 4WD Stopped Working - Testing ESOF TC Motor?
Jan 22, 2016
A buddy of mine has a 99 F250, and the 4WD stopped working. The 4wd light in the dash does not turn on with the key with the rest of the lights. There is a Low Range light that does turn on. He took it to a shop/dealership and they said the vacuum was good. They also swapped in a different GEM module, which didn't change anything.
I swapped the relays under the hood - no change. I keep reading that there is a two wire plug on the transfer case I can test for voltage or to manually power the motor. Where is it? I see two plugs - the blue one on the left has 4 wires, the black one has more. Or is that not the shift motor I need to be looking for?

I am having some issues with my 2003 f250 6.0l 4x4. I cannot get the 4x4 to engage. There are no lights on the dash and no power to the switch other than the light. It doesn't matter if I have the hubs in lock or auto. It just seems like i have no power to the system. I have check all the fuses and they all check fine. I also check the transfer case motor and it seemed fine. I must be missing something. This truck is worthless without 4x4.

My HVAC blower motor stopped today while the wife was driving the F250. I thought I should swap relays (with the heated mirror relay - same Ford Part Number) to rule it out or identify it as the culprit. However, since these are close to the firewall, I have a hard time getting the grip and leverage to pull the relay out of the Battery Junction Box (BJB). How to make this a bit easier?

Truck: early 99 F-250 diesel lariat
I am trying to troubleshoot my ESOF not working. Let me start out by explaining the issue. A month or so ago it worked fine, and I took the truck in to get a damaged transmission and transfer case fixed. The shop tried to screw me out of a lot of money thinking I'm just some kid, but I know a fair amount about what the problem was so I called them out on it and they basically said tough and refused to give the truck back. Got the police involved and they got in trouble for fraud, but took sledge hammers to the transmission and transfer case to get back at me I guess.
So I took it to another shop to get a whole new transmission and transfer case. After all that, and also I removed the dash to replace a switch, the ESOF does not come on. The light for 4x4 comes on when starting the truck, so it works, it just does not come on when the switch is put on either high or low 4x4. The wheel hubs are also brand new and I tried in both free and lock and nothing. What to check? I'm thinking either they forgot to plug something back in when they installed everything, or maybe I messed up the switch itself when I pulled the dash off.

2002 Superduty 7.3 ESOF. I used 4x4 last week and the transfer case engaged and disengaged great. Yesterday I tried and got no response. I got home, checked the 2 relays by the brake booster and checked the fuses related to the ESOF system. Those check out good. I ohm checked the position switch on dash(2wd, 4x4 hi, 4x4 low) and it passed. I bench tested the electric shift motor and it works both directions just fine. I also jumped the relays and the transfer case shifted to 4x4 hi and low fine and the cluster indicator lights light up properly. Put everything back together, took a lil break and tried it again with key on truck off (so I can hear the transfercase) Went in and out both HI and LOW great about 4 to 5 times then got stuck in 4 LOW. I manually got it out by jumping the relays again. Tried again today. It went into 4x4 HI great, put in neutral brake on and went into 4x4 LOW great. But it will NOT come out of 4x4 LOW. Im stumped and don't want to just start throwing parts at it.

2012 f250, fog lights stopped working and tried fixing yesterday. I'm getting 12.8v at the plug but as soon as you plug the light in it goes to 0. Ran a new ground from frame and the hot from plug and still nothing. High beams off, truck running and switch pulled out. Bulb is fine, hooked it straight to battery and it comes on. I though it was a faulty ground but by running a separate ground and still nothing. I'm at a lose.

The transfer case on my 2001 F250 Powerstroke will not engage when the ESOF is switched to 4hi or 4lo. I checked the fuses and they are good. I removed the electric motor on the side of the transfer case and while it was hanging down with the two plugs attached I did not see any movement when the dash switch was moved to the 4hi position. I used a wrench to manually shift the transfer case and still did not get the transfer case to engage. What next?

I am in the process of rebuilding my front end and have found that the nipples that screw into the top of the knuckles for the ESOF system are rusted and need replacing. I'd like to keep the system as close to original as possible, but have had no luck in finding a replacement. What the appropriate Ford part number is or where I could pick up a suitable replacement. This would be for a 2001 F-250 4X4 with the V10.

I have a 2001 F250 4x4 and the ESOF switch not engaging hubs, currently I have no 4x4 lights coming on in the cluster when i turn the switch. I am not experiencing any of the vaccum symptoms that most people are suggesting. I When I turn the switch i also do not hear any relays clicking. Relays have been tested, and i waited for the 45 second transfer delay that the manual mentions. ESOF switch has power, and is working properly (I know because I bought a new one in attempt to fix the problem) Basically I have no responses from any of my 4x4 indicators or parts.

I have an F-250 diesel 2004 and about six months ago it started acting really crazy. Basically most all of the dashboard electronics stopped working like the speedometer , odometer, gauges, etc. additionally all of the interior lights, and the radio stopped working. Now it looks a lot like the attached picture when I'm driving the truck. All of the lights are lit up on the dash panel but nothing actually works. I thought at first that a bunch of fuses might be blown but I have replaced nearly every fuse that has anything to do with any of the affected systems. What the issue might be.

I have a 2003 F250, 4x4, 5.4L and today my fuel gauge stopped working. I don't know if it had anything to do with a stall, I was on an exit ramp and the truck cut off, I quickly restarted and no issues after that. Other than the fuel gauge not working at this point.
I looked at the fuse panel diagram and there is no fuse for just the fuel gauge. The only thing I see is #35, instrument cluster. The rest of my instruments are working, so what else would cause the fuel gauge to stop working? It had a little over a half of a tank before the stall, after the stall it went down to less than half. I filled up shortly later and it's just stuck at less than half.

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.

I have a 2000 f250 CCSB 4x4 with the ESOF auto hubs. The auto hubs won't engage automatically. They work fine manually. The transfer case is engaging and correct lights are coming on. There is a little bit of vacuum coming from the vacuum switch but it doesn't seem like much to me. All the dash HVAC controls work fine though. I Lubed and cleaned inside the hubs according to Guzzles directions.
While torn down, I blew through the vacuum port on the outside of the hub and there was little to no restriction. I don't think there is enough vacuum to pull the hubs, but is that possible if all the dash controls work fine? What pressure should it take to engage them? My next step is to pick up a vacuum pump and see if I can engage them with it.

So one day my 4 wheel drive just stopped working, when I put in 4hi nothing same with low, the light on the dash doesn't even pop up and it doesn't engage. I've done about everything I could think of doing besides replacing the motor for it and the wiring, I hate getting stuck...

My drivers window will not work at all but when I push the button I get a clicking in the fuse box. The other 3 windows partially work but will only go up or down in small increments. I have tried holding the button and slamming the door and this allows the other 3 windows to work. I thought it was the switch so I replaced it and that was not the problem. Fuse and relay seem to be fine. If it was just the driver window I would think it was the lift motor but with the other 3 windows on the fritz I have no clue.

I'm hoping this might be a "quick fix". Got in the truck the other day and my power driver's seat had no function what so ever. Not a big deal for me as I drive with the seat all the way back but the complaints are starting from my wife so it's time to find a fix.
This is the first F250 I've had so the wiring is a little new to me. I checked the fuse panel and the fuse seemed okay I swapped #9 out for #22 as they are both 30A and I don't need the trailer at this time but still no luck.
Are there any other systems tied into the driver's power seat, any wiring harnesses I should check or perhaps a fuse that is not shown in the owner's manual? My truck is the 2013 Gas F250.

I noticed that my 4WD is only working now when I manually lock the hubs in (they have that options!), and the air blows out the defroster when I shift, so it looks like I have a vacuum leak. Where are the typical leak points on a 2006 F250? What's the best way to confirm a leak (other than just replacing all of the hose)?

I have a 2001 F250, 5.4, 4X4. My ignition key stuck in the start position and when I pulled it back to the run position, everything seemed ok. As I started down the road, my speedometer stopped working and my overdrive light was flashing. Also my turn signals had stopped working and my A/C clutch didn't engage. Figured I burnt a fuse. I looked in both the under dash and power distribution box and all seemed well. I checked the fuse for the turn signals/flasher and it was fine. The flashers worked. Thought I might have fried something so I replaced the ignition lock and switch. Also my service engine light came on throwing a code for the vehicle speed sensor.
Looking for solutions on this forum and the internet, I learned that the turn signal switch could have gone bad and the VSS sensor is on the top of the rear dif and an easy fix. Well replaced the sensor but nothing changed. So I went back to the fuse box. Examined every fuse, big and small and I found a 10a with a small space. This was #24 under the dash. From the manual, "#24, 10A, A/C clutch, Blend Door Actuator, Trailer Tow Battery Charge Relay Coil, Four Wheel Anti-Lock Brake System (4WABS), Turn Signal." Replaced it and everything went back to normal. Turn signals work, A/C clutch works, no flashing overdrive light and speedometer works. All from a 10A fuse. If you have any of these symptoms examine all the fuses carefully. There's a 20A fuse for turn/hazard lamps and this other one buried that's only 10A.

My father-in-law has a 2008 f-250 with the 5.4. as he was driving a while back all the gauges of the dash quit. The engine still kept running without any noticeable difference but when he shut the engine off and tried to restart, it wouldn't even crank but the security light was flashing. He tried starting it again a few hours later and it started just like normal and ran fine.
He has had this problem occur several times in the last few months, but the other day it repeated the problem again and would not restart for about 5 days. He has tried charging the batteries, changing relays, checking all fuses and finding none blown, scanned it with his code reader, and checked the steering column for bare or rubbed wires.
