It is much easier to test the bulb before you pull apart the dash.
This is a self test of the instrument cluster functions on 1998 and newer Jeep Cherokee's XJ
1) Push and hold the odometer reset button.
2) Insert the key into the ignition and turn it to the Run position, but don't start it.
3) Release the odometer reset button.
The instrument will enter the self test mode. The gauges will start moving in a sequence and most of the indicator lights will turn on.
You can also disconnect the wire harness from the 4x4 lamp switch on the transfer case and test the 4x4 lamp with a paper clip. I think your transfer case 4x4 lamp switch has a dirty connection or is going bad.
