Ford Super Duty (1999-2016) :: 2003 F250 - Cannot Get 4x4 To Engage / ESOF Not Working
Mar 29, 2016
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.

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?

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?

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.

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 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.

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)?

Wipers/washers didn't work on 2003 f250. No blown fuses in system, supply fuses are 106 and 33, removed wipers and found no voltage on dk/grn wire of connector (fuse106). Turns out that the wire bundle had chafed a wire near the inner fender liner to the point that it cut the wire and broke the connection.

03 F250. 5.4 2v ... I purchased it a month ago.
Squeak under the hood. It appeared to squeak in relation to the movement of the tensioner......simple right? Replaced Tensioner and Belt..... Still squeaking.
AC not working at all. Compressor never kicking on.....replaced compressor, accumulator, and orifice tube. AC works now!.....squeak still there....
Notice fan wobbling.....shut truck off.....fan clutch shot... replaced....STILL SQUEAKING!!
Obvious answer....sound still on that side of the engine....Idler pulley....I just replaced it and the dang truck is still squeaking!!!!!!!!!
All that's left is the harmonic balancer, alternator, and power steering pump.......What could it be?

My truck: 2001 F250 V8 Triton Automatic 4x4
Problem: 4x4 won't engage
Symptoms: No dash lights....nothing happens when I turn the 4x4 switch. When I start the truck I hear what sounds like a motor (transfer case motor maybe?) trying to switch (even though my dash switch is on 2WD)... It tries three times and stops.
What I've done: Checked fuses ...they appear ok to me
I don't have a maintenance manual yet ...
The 4x4 used to work up until about 2 weeks ago. Started having a hard time getting it to go into (and out of) 4x4 and then it just stopped all together.

F-250 2005 XLT 5.4L 4X4. Had ford for a few years now (Escape as a personal vehicle and econoline as business vehicle). Now I'm having a little problem with 4x4. It wont engage. Worked fine last week and now nothing! I did check all the fuses and when i switch to either 4Lo or 4Hi I can hear a clicking sound behind the switch but feel like it's getting blocked or something. Tries a few time then stop...

I have a 04 ford f250 superduty... I tried to use my 4x4 today and the front wheels would not engage using the ESOF. The light comes on in the dash saying its in 4x4. i do not believe i have a vacuum leak because it doesn't switch over to the automatic setting for defrost. what else could it possibly be I'm stumped at this point.

4x4 will not engage. 4x4 light on dash does not come on. Can not hear motor switching into 4x4. Check fuses under dash all looked good.
Truck is a 2004 F250SD V10 ....

My overhead display quit working earlier this week. The truck has 120k miles. Is this display on it's own fuse? I only used it for the outside temperature readout but I would really like to get it working again.

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.
