Ford Excursion :: ESOF (4wd) Not Working - Wiring Malfunction?
Aug 28, 2013
My Excursion is stuck in 2wd. It worked one morning, then it didn't that same afternoon. I've checked all fuses that resemble a related fuse in the fuse box.
I've replaced the dash switch, Transfer case shift motor and ESOF/GEM module behind the glove box. I've swapped around the relays under the hood on the drivers side fender well.
I ran a hot & ground to the 2-wire plug on the x-fer case shift motor to have it move the ex back into 2wd (replacing the shift motor required me to manually put it in 4hi with a wrench).
At this point, I'm thinking it's a wiring issue? Where to go next?

I posted earlier about the tranny in my 01 Ex v10 having a transmission problem. The show looked at it and found the O2 sensor had shorted out and in some way sending the truck in to limp home causing the tranny fuse to blow????
Any way they fixed it or so they said and I drove it for a few hours and it did fine. The next morning I drove it and it blew the fuse. (under hood box I belive #19) I took it back to the shop and they beat and banged on it....got it wet etc. and can not get it to do it again. I know whe have an electrical issue but what all runs off of the fuse that controlls the tranny?
Is there any online wiring diagrams of excursions or superduty drive trains? Where all to look for the problem?

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 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.

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 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 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)?

Just bought an 04 Super duty with the factory plug 7pin and 4 pin plug. Checked the fuses and finally tracked down the 2 relays under the hood but can't seem to find anything wrong. Everything on the trailer works except for the running lights. Is there another fuse or something I have missed? Trailer works fine on my buddies Duramax and worked fine on my old 97.

Need a wire diagram. I have a connector in the cab that has red,blue,lt green,white wires. It's causing my brake lights not to work. I need a wire diagram that shows were they go. I can't find these wires in my Haynes manual.

Turn signals quit working on my 2006 E-150. Swapped out the relay under the dash and it did nothing. Also noticed the brake lights aren't working. The headlights and taillight a are working. I pulled the fuses under dash for the lights and they tested ok. I did notice the flasher relay was making clicking sounds intermittently even when not touching anything.

I'm not too knowledgeable about wiring and electrical systems. I'm getting a P1451 code (EVAP Control System Canister Vent Solenoid Circuit Malfunction) on my 99 4.2. I've read that it could be a bad solenoid, bad wiring, or a blown fuse. So far I've;
- checked (and changed) the related fuse
- checked the wiring for damage at the connector
- checked voltage at the connector (12 volts)
- checked the resistance at the solenoid (around 60 ohms)
- actuated the solenoid with a 9V battery (can hear it opening and closing)
I haven't had a chance to check the wiring all the way back up the frame to yet, but I noticed that the ground at the trailer wiring harness has broken off the frame. Would this potentially cause a fault in the upstream wiring? I'm going to slap a new connector on and bolt it back down anyway, but as it's Labour (Labor) Day I'll have to wait for the stores to be open tomorrow.

While changing out a light bulb in a door panel I had to use pliers ( bulb was broken ) I knew I would blow a fuse but it has taken out the dash board, power windows and even the radio I have checked the CB 601 and that's fine any ideas what to look for next ?

I have read several of the post on here about speedo's acting up, but I'm not finding anything that pertains to my specific problem. A few months ago I bought a 2000 Excursion, it currently has around 179,000 miles on it. When I got it the ABS light was on and this site is actually where I found out to replace the sensor on the rear end to fix that. My problem is that until a few weeks ago even with the ABS light on my speedo worked just fine and then it started acting up every time I hit the brake pedal and then eventually quit working all together and my cruise control light would flash as well as the OD light.
I replaced the sensor in the rear end and also found out about a recall for the cruise control and had that repaired as well. Now the ABS light is no longer on and the cruise light is not flashing, however the OD light still flashes and 95% of the time my speedo does not work at all. On Monday while heading to town it started working, hit the brakes and all was good, set the cruise control and used it all the way to town, but as soon as I hit the brakes the needle started jumping around and went back to zero and stayed there. I have ohmed the sensors and wires from sensors to harness under the hood and all seems good. The only code I can pull with my meter is P0500 which is just a generic code.

Early 2000 vs 2001? Looking for info on replacing wiring harness under the dashboard?
Is there enough clearance to pull the harness without removing the dashboard?

What is this supposed to go to? Found it just flopping around under the hood while we were replacing a fuse.

I removed the rear radio controller from the back of the console and installed a power inverter in its place. It fit great and everything went smoothly. I should have known it was too easy... I now have no sound coming out of the rear speakers. I assume there is a way to jump the wires to allow the speakers to work, but I'd need a wiring diagram. Right now I have the controller hooked up and buried in the console, which I guess is fine. It's just annoying.

I have a 2005 6.0L Excursion. I'd like to do the high idle mod. From looking in the tech folder there are two options.. Option #1 being for 2003-2004 trucks and Option #2 being for 2005+ trucks. The assumption for Option #2 is that there is wiring from the factory for the upfitter switches. My engine build is a 2004 and I could not find any evidence of the orange upfitter wires so I proceeded with Option #1.
I find wire 294 (white/light blue strip) with no problem.. What I can't seem to find is wire 322 (light blue/yellow strip). I can find the 4 dummy (extra) wires to the engine compartment (Red, White, Blue, Black solids) yet I only find 3 blunt cut wires capped with tape... The colors on those are white/orange strip, light green/white strip and yellow/white strip - no sign of the light blue/yellow strip wire.
Is there something unique about the 2005 Excursions?

Bought a Powermaster 250amp alternator for my '05 V10. Says I need to upgrade my power and ground wires to 4 gauge with fuse on power cable. I don't really run too many accessories other than HID heads and fogs and 2 DVD screens for the boys.
Do do I really need to upgrade my wiring? Can't imagine I'm pulling much more amperage than stock (130amp on my truck).
