Thanks alwaysfords2, I checked the fuse to the transfer case shift motor today - it looks fine. I will do a more thorough look through other fuses when the weather warms up - high of ten degrees F today...bbbrrrrrrrrrrrrr. I am thinking it may be related to the GEM system!? Still looking for other ideas. I think I will also check to see if I am getting power at the transfer case shift motor.

I've also read of people having temporary luck hitting the shift motor and waking it up, sort of like hitting a starter that has a dead spot on it, so after you check the power, give it a smack or two.

Thanks for the tip on giving the transfer case a pop. I had read that elsewhere too. I did not get to that point in troubleshooting but was able get the 4WD working today. I rechecked the transfer case fuse, as well as checked all of the GEM (generic electronic module!?) fuses. The circuit for the 4WD selector goes through the GEM. All fuses looked okay, but there must have been a bad connection in there cause after checking and reinserting the 6 or so fuses, I started her up the AWD and 4Hi are working. yeah!! Just goes to show - start with the simple stuff first!

Simple and free. Doesn't get much nicer than that.
#24 of 60 2003 Expedition 4x4 problems
Jan 23, 2010 (7:51 pm)
Heres the story... 2003 E.B. Expedition, 5.4L, control trac and traction control. It started jumping out of 4 wheel drive a couple years ago and slowly got to the point where it wouldnt go into 4 wheel drive at all. Didnt worry about it since we have another AWD GM suv to use when roads are bad.
Fast forward to today. I finally decided to take a look at it. Here is what it does: Select A4WD on ice. Get rear tire spin only, then the 4x4H light illuminates for some reason. Select 4x4H and i hear solenoid by the seat belt click. 4x4 indicator illuminates on the dash and only have rear tire spin. Put trans in neutral, foot on brake, select 4x4L. Transfer case engages in low range and 4x4L indicator illuminates. Rear tire spin only. Also crawled under and listened and felt the transfer case shift motor and it seems to be working when someone switches from 2HD to 4x4H
Now today, I am hearing a noise like a rattle ONLY when 4x4 is selected and while I am getting rear tire spin. I thought it was coming from transmission/transfer case area. My wife says it was coming from the front of the truck (hubs?).
I changed the transfer case fluid with appropriate fluid and only then, during a test drive, the ABS light and (red) brake warning light came on. Also received a "check control trac" message in the MID.
I am thinking that it may be the hubs but I was told that if they fail (loss of vacuum by hose or seals) that they fail in a locked position so I should still have 4x4. However, this summer, I did notice a clicking sound from the hubs when turning the wheels sharply in either direction in 2WD but no drive line bind like you get with an operating 4WD system.
Any thoughts? I m at a loss. Tear apart the hubs or should I pull the transfer case and inspect the internals? Could this be a speed or ABS sensor?

When you have it in 4WD is the front driveshaft spinning (all wheels off gound) if so the tranfer case is doing it's job! The hubs are problematic on this vehicle and yes they are vacuum controlled by a Integrated wheel end solenoid (IWE) The solenoid simply diverts the vacuum when you command 4WD engaging the hubs. You won't be waisting your money replacing the locking hubs...they will cause clicking noises and go bad often... then check to see if the IWE soleniod is being controlled and working properly. Make sure it has power to it (fuse) and switching vacuum like it should. They are usually located in the right rear of the engine compartment by the battery. It has one 2wire plug and 2 vaccuum lines running to it. Hope that helped.
#26 of 60 2003 Expedition and Transfer case input seal
Jun 30, 2010 (8:07 am)
We have a 2003 Expedition with 120,000 miles on it. While at the Ford dealer for an oil change this morning, I was told that the transfer case input seal in leaking fluid -- and they want $400 to replace the seal. Assuming the dealer is correct, what happens if we don't replace that seal?

Just want to let everyone know that the problem was the nut on the end of the front axle behind the dust cap that had stripped off. Now nut and cut threads, I now have 4 wheel drive again

a year later, but this worked for me too! (fuses good, but pulled and reseated all awd and gem)
#29 of 60 1998 ford expedition stuck in 4 high
Feb 28, 2011 (10:14 am)
I have a 1998 ford Expedition we put it in 4 high during our last snow storm and now it won't come out. We have checked all of the fuses, pulled forward and backed up in a straight line, basically we have tried everything we can think of. Does anyone have any idea what to do?
