The brakelight activation switch on top of brake peddle had come loose,not allowing lights to come on and affecting circuit to 4wd selection switch. I fixed the brake peddle switch and it solved the problem.

On the transfer case Transfer Case - Electronic Shift
The four-wheel drive electronic shift-on-the-fly feature electrically shifts the vehicle transfer case between 2WD, 4WD HIGH, and 4WD LOW. The system mode is selected by the operator through the mode select switch (MSS) on the instrument panel. The operator is informed which mode the system is in by two instrument cluster indicators: one for 4WD HIGH which appears as 4WD, and one for 4WD LOW, which appears as 4WD LOW. Shifts into 4WD HIGH can be made at any speed. When shifting into 4WD HIGH with the vehicle stationary, tooth blockage may occur preventing shift completion. When the vehicle is driven above 8 km/h (5 mph) the shift will complete. When shifting in or out of 4WD LOW, the four-wheel drive (4WD) control module requires that the vehicle speed be less than 5 km/h (3 mph), the brake pedal be applied, and the transmission be in NEUTRAL (automatic transmission) or the clutch pedal be depressed (manual transmission).
The gearmotor encoder assembly is mounted externally on the transfer case. It drives a rotary cam which moves the mode fork and range fork within the transfer case between the 4WD HIGH, 4WD LOW, and 2WD range positions.
The four-wheel drive (4WD) control module controls the gearmotor encoder assembly that shifts between 4WD HIGH, 4WD LOW, and 2WD modes.
Only 2 things could be wrong. The brake light switch mounted by the brake pedal arm or the shifter solenoid. Column shifter solenoids you can buy. But console shifters, you have to buy the entire shifter to get the solenoid.
check the rods are not bent at transfer case try putting it into gear with a shifter from underneath ,if no go must be internal also try backing up if possible.
If your sure it is acually going into gear than check the auto hubs, they go bad alot. also you can with help from a 2nd person jack the truck up all 4wheels put the truck in 4x4 and drive and see if both drive shafts spin if they do its the hubs if the front one doesnt, its the transfer case
In order to get into 4 wheel drive low, make sure the shifter is in neutral before switching the dial to 4 wheel low. 4 wheel high and 2 wheel high can be switched into in park or in drive but 4 wheel low can only be obtained in neutral. If that does'nt work you may have an electrical or switch problem. Hope this helps. God bless!
Chances are the linkage for the transfer case is out of adjustment try loosening the adjuster bolt and put the 4WD shifter into the position 4WD high or low (depending upon which position it's lockup in) then lock down the adjuster bolt, try to shift out of 4wd sometimes you need to go forward and backward with the vehicle to get it out of 4wd, when you get it out of 4wd you may have to fine tune the adjustment to get it to engage and disengage smoothly it's a trial and error thing keep resetting adjuster until you get the desired effect.
