Scan for a fault in PCM then diagnose, probably related

well not sure what style shifting it has. if its the floor shifter to select. you need to have the truck in neutral first before changing the 4wd. same thing with push button shifting on the newer trucks. it just works easier for the parts to move not being in gear. if it wont work with the shifter then you might have something that is broke or jammed.

I recommended checking fluid level in trans. first. If that's good try starting the vehicle and shifting from forward to reverse and giving it a couple seconds and either gear so that the trans can prime its self. Last resort drop the pan and put in a new filter and fluid.

That maybe the case however I would check to make sure the linkage from the 4wd shifter did not pop out from the transfer case first.

The best way to do that is to start the engine put the transmittion in neutral with your foot on the brake and pull it out of 2hi,,,put the trans in park then move shifter to 4 hi or lo.

There are some vaccum lines that go to your axle. there is a disconnect there and a switch that lights up your dash light when engaged. I would first make sure they are still connected and not damaged. The vaccum signal to engage and disengage comes from the top of your transfer case right under the shifter boot. To test if you disconnect is working, apply vacuum to one or the other side of the diaphram for the axle disconnect and try it out. otherwise you may have lost vacuum somewhere or you have a bad switch on your transfer case.

Look for damaged wires, or something bent, on the Auto Disconnect Device on the front axle before you do anything else. The 4WD HI light is not coming on because the front diff is not engaging.
Re 4 LO: In 4 LO, you ar NOT getting "4 LO", what you are really getting 2WD LO, because of the output gearing of the transfer case.
In any case, your front diff is not locking in, in either mode. The A.D.D. controls the 4 Hi lite.
