The transfer case lever is the short one on the right, there should be a placard right on the glove box doorHow do I confirm and fix that?
2H - 4H - 4L
Pull that lever back to the left and forward to the 2H position. It will look like it's way to the right if it's in 4LO
If this doesn't actually do anything, then I suspect the linkage is broken, and if you take the cover or boot off
you will see down in there and know fairly quick if it's buggered.
