I amhaving similar problems with my 2005 FX4, it would not go into 4Hi or Lo, I keep trying every now and then, and one day it does go into 4WH, GREAT!!!!!! now it won't come out of 4WH, so I try putting it into 4WL, it goes in, and now won't come out of LOW. I replaced the shift motor last summer when this happened, and it fixed it for a few days, then stopped going into 4WD, I don't think its the IWE's cause it wouldn't go into 4WD and drove in 2WD no problem, until the ESOF finally did send a signal to the shift motor to change to 4WD.

I think my shift motor is not getting the signal to change. I have also replaced the vacuum solenoid, so that rules that out. My mechanic did say I had no power going tot he shift motor at one point when he was working on it, but then power came back.

I had this problem too, and after several days of frustration finally re-checked the switch. And that was where the problem was. It was intermittent, sometimes it would work, other times only some of the contacts would work. I would get the 4X4 to engage but not disengage. Sometimes the indicator light would work, other times it was out when the switch was on.
Hope this helps.

I had a similar Issue

your 4x4 is a vacuumed activated system. Tapping your hubs with a hammer may help loosen up a stuck actuator. There is also an electric motor on your transfer case. Mine would hang up when I first got my truck due to that the previous owner never used it. I had to tap the motor a few times and then it started to work. Since then I engage it at least once a week to keep it free. There is a lot of info on the net and probably this site on how to check your vacuumed system for leaks etc. good luck. Cudda
