Not sure if your jeep has the vacuum front axle disconnect, but if it does that might be the problem.
When you go to 4WD low range, are you sure you have 4WD?
The plastic multi-colored vacuum lines they use in this system are impervious to all known automotive fluids, with the one exception of battery acid.
Curiously AMC decided to run these lines (in fact mounted some system components too) right under the battery tray.
If any of these lines appear to be cracked, then they are sucking air. Not a good thing in any vacuum system.
You can google "Posi-lok" if you want the cable deal (I chose this), or you can re-do the lines (cheaper).
If you go with the re-do, here is a diagram;
The storage tank looks like a black plastic baseball, & the control switch is on top of the transfer case.
If you don't have the vacuum disco, someone else will need to help.:-|

All YJ's have the vacuum disconnect, and your '92 is slightly different than the diagram above. Your 4wd light switch is on the front axle and not the firewall as it is on earlier YJ's.Your 4wd light will likely work when the disconnect is working properly and is engaged. You can unbolt the disconnect from the axle and, with engine running, watch the fork movement when shifting from 2hi to 4hi.If it's not working and you need 4wd in a pinch, unbolt the disconnect from the axle and slide the shift collar to lock the 2 axleshafts together. Install the disconnect upside down and it will keep the shift collar engaged.
