Question about 1990 Jeep Cherokee Limited
Sounds like a locked up servo and it (Tranny) is wanting to be in 2
gears at once. This will blow fuses to prevent a locked up tranny.
It sounds to me like the wire you found this inline fuse in, is the power (12V) line that goes to pin C15 on yout TCU connector. If you lose or take away power from this pin the tranny will go into a full manual mode. Meaning it just goes straight to whatever gear you have the gshifter in. The good news for you is that for a temp fix until you find your short. You can cut this wire and run it to any (12V) switched source. Switched meaning it turns off with the ignition switch.
Test it and keep us updated.

The front axle connects 4wd by vacuum. check the vacuum hoses that run to the actuator. Pay close attention to the vacuum hoses running underneath the battery as battery acid can eat thru those hose easily. Good Luck.

Four low is almost never used. I use it on very steep rocky or muddy trails in the woods or to pull someone out of mud or a ditch. Though some will shift standing still it is best do do this while rolling. Four high can be shifted at low speeds of 2 to about 35mph (higher also but not really good idea) Low can only be shifted between 2 to 10mph. If you find yourself stuck and unable to shift because you aren't rolling you can also turn the engine off, engage the transfer case and re-start. That avoids having the gears clashing together. Best rule is if it begins to grind, don't force it.
