Go to the engine compartment where the relays are located with the fuses. Check or replace the 4 wheel auto engage relay , maybe is not working. Is very clearly mark, I believe is the top right one looking at the bost front front of vehicle to the back. There is a diagram drawing of each relay in the cover, so you can't go wrong.

Start the car
put in " N"
turn the 4X4 switch on
Then put in gear..
What do you see now?
Do the same in reverse when you take out of 4X4

I have a 96 with loking hubs. as long as you have locked the hubs(both) and the bulbs are good. Sounds like a sticking sensor.
