I have a 1997 Ford Expedition that is stuck in 4wd. Could someone please tell me how the IWE's control the 4WD on this vehicle if in fact they do.
If they don't could you please tell me how the 4WD is engaged and disengaged. I have the vehicle up on jack stands and I have verified that it is in 4WD. The drive axle coming out of the transfer case turns all the time which someone told me is how it is supposed to be. I see a lot of discussion on later models and the vacuum lines going to each wheel, however this is not the same design that I have.
I would sincerely appreciate any help you can give me.
