When you switch it from 2H to 4H you can push the switch at any speed but if you switch to 4L the car must be stop and the shifter is in neutral position.
Anyway here is my suggestion.... I would check the switch it self 1st for proper contact, also check the owners manual if there is a fuse for 4X4.
The worse scenario is the 4X4 computer is dead and if you have problem with transfer case you would notice a whining noise.

check the trasfercase shift control module and wiring
it's located on the passenger side
remove the carpet thresh hold
remove the kick pannel they are held on by clips
the module is behind the kick pannel
disconnect the module harness and see if it is corroded if so you need to replace the connector and the module
let me know if thats not it but i have done lots
