That's what I was hoping for but today I figured it out. There is a switch on top of the transfer case that has a 98.73% probability factor. The only thing is it's a $50 switch from Dorman. This there # if anyone ever has the same issue. Dorman 600-555. https://www.amazon.com/Dorman-600-555-Transfer-Case-Switch/dp/B01N0BPYAFMaybe someone will chime in that has had this problem and know of a fix, good luck
