Question about 1995 GMC Jimmy
Transfer case not engaging when the button on dash states that transfer case should be in either hi or low depending on the button you select
Check the solenoid on the transfer case - it is vacuum actuated and you may have a problem with the vacuum line.

SOURCE: intermittent 4wd on 98 jimmy
the module is what i would suspect. and i do believe it is in the r kick panel. i've seen the button pack on dash go bad too, but module is best bet.

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

I just fixed a friend of mines 96 yukon...shift to neutral press 4H and u can hear the actuator make noise (we even replaced it with a new one his idea and the same thing happen as old one), so as he hit the switch for 4H i layed under it (on 4 jack stands) and I could hear the motor on the transfer case make a loud noise (well thats working) and before all this I asked him did u check all your fuses (he said guarnteed to be all good) one night it was bothering me so i looked through the owner manual for the yukon and in the fuse box on driver side by the door there are (2) fuse for the 4wheel drive unit,pull one of the fuses good...pulled the other one and it was blown put in a new fuse and it works like brand new..pull fuse for anything that has to do with 4 wheel drive componants,

Ok the drive shaft will spin thats good. remove the front driff actuator and see if the plunger extents. if it doesn't check that the power and grond ar ok. If they are then replace the actuator. Just so you know the two actuator may be diffrent. If it has been replaced no problem. If it hasn't ever been replaced then ther is a updated part it come as a kit witha harness spacer and actuator.

Testimonial: "Fixya pointed me in the right direction to find the problem. It was in fact the front actuator which was not expanding. The 4wd is working. Thanks."
