Pull the kick panel on the passenger side. there is a small box mounted there that is the computer that controls the actuator for the 4wd system. this is notorious for problems due in fact that the connector likes to pull out and away from the module. I had the same problem and the solution is simple.. take a long zip tie and get it between a few of the wires and around the module. tie it in and have a nice day.. it wont come off or try to pop out anymore and you should have no issues getting into 2wd, 4wd h, 4wd L.

Could be the actuator motor on the transfer could be stuck or bad connection. Check to see if your gett power to the plug on the transfer case.

Check the switch on the transfercase remove the vacume lines if there is oil in them the switch has to be replaced and the lines should be cleaned out you should also check under the battery tray to make sure the boot is not ripped that controls the leaver to engage the front axel
