There were no codes, however he was able to make the 2wd, 4hi, and 4low lights come on in the switch module (so I assume that means the switch is fine?). Now... should I just get the "encoder motor" or see if there is a program update or what? He said nothing about any new flash updates "reproggraming" for this. I need an expert answer. The encoder motor is around $250.00 now if I buy online. I should be able to install myself. I really want this fixed.

the problem you have is a dealer tech unable or unwilling to give you the dtc drive train codes.
go to another repair shop that will give you these failure codes.
with the service 4wd Lt on this must have failure drive train codes..
then post back the dtc drive train codes ..with this the forum members will get you going in the right direction..
you have a componet failure not a need for any update !
