Get it on a good engine/transmission/transfer case/and ABS capable scanner and get codes.
Watch and check the speed sensors real close.
ABS or speed sensor problem will disable 4 Wheel
Post back code no.
And we caqn help.

233 0r 236 transfer case?

How and what kind of a scanner did you use to check for codes.

236 will store codes if there is a problem?
Is the scanner showing anything on transfer case operation or data?
Will it run the shifting test?

If you are refering to the encoder shift motor.
Some of them can be repaired.
Some have a cracked case that lets water in and burns up resisters.
Good luck
