Ford Excursion :: ESOF (4WD) Quit Working?
Oct 5, 2014
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 have checked the fuse number 38 and it's fine, and I've also checked the bulbs and they look good. Where else do I look to check for problems with my reverse lights not working? I just had my transmission rebuilt, and wondering if a sensor or something went bad?

Tonight my wife and I drove ex to store and out to eat . We got back home and the wife opened the glove box and the radio quit working. And when she closed the box the radio came back on.

I have a 2002 excursion xlt 4x4 v10
The door locks quit working. The previous owner did the tin foil repair... I replaced the four door actuators today. Now all of the doors lock and unlock on the manual buttons. The fob doesn't work on any door.. when i try and use the door code pad, the locks go into a cycle.. the keep trying to operate by themselves. I had to disconnect the battery to get it to stop. I can't find the door lock relays. I have most of the dash out. Where these are?

I have a question on my '00 7.3. Cruise control just quit working. From reading the threads/forums I have gotten some ideas, but how about no dash light when turning the key to on? Nothing with the self test also. How can I troubleshoot the switch in the steering wheel? I could also have a bulb out in the cluster, but either way- no cruise function.

I'm working on a 2003 that the front wiper and sprayer quit working on. The rear wiper and sprayer still work fine. We replaced the multifunction switch and no change. I would like to test the motor before we keep throwing parts at it.

The fuel gauge sender quit the other day so Im replacing the pump assembly. I believe in replacing fuel and ignition related parts with factory equipment. So I was going to get a Ford Motorcraft pump, but my wife checked for one through her work(local parts store). The counter guy found one that said original equipment, called them and was told "It is the same pump that gets installed on the assembly line". Well it came in today and its a Delphi. I was expecting a Ford pump. I associate Delphi with GM and I know GM pumps go out all the time. I know Ford pumps go out too, but I know several people with GMs that have replaced pumps multiple times within 100000 miles. Is Delphi worth taking a chance on?

I have a 2001 Excursion, 6.8 V10, with the factory fog lights.
The fog lights worked fine, until a few days ago until they suddenly stopped working when just the parking lights are on.
I can still pull out the switch, the indicator light does not come on but the parking lights still work. When I turn it to the headlight position with the switch pulled out everything comes on and works like it should.
I tried checking the fuses but I didn't see one labeled in the manual for the fog lights so I don't know for sure which one to check. Could I possibly have a bad switch?

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)?

My air conditioning on my 02 is having a issue, when you first start it and run the ac all is well and it cools perfect but then after a while it will quit working all together no more cold air, shut it off for a bit then it starts working again and repeats the process, charge is fine, been doing this all summer, it verys on how long it will work somethings for 5 minutes other times 40 minutes give or take, any thoughts?

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.

Troubleshooting 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?

2002 Excursion 7.3 4x4 160,000 miles trans rebuilt @100,000.
Yesterday while driving on the freeway our Ex all of the sudden felt like it was in neutral. Coasted to the side of the freeway, it would not move in any gear including reverse. There were no bad noises/sounds or anything like that.
The Ex ran great before this, with no signs of the trans going out. My question is what could cause the trans to go out all at once, sure doesn't seem like something was wearing out.
