I have the exact same make/model and I am having a very similar problem. I have had my vehicle for four years, it has approximately 130,000 miles on it. My vehicle will not engage from 2hi to any other feature (4hi, 4lo, or 4 auto) I just get the blinking yellow light when I try to change from one to the other. My gas gauge has a tendency to jump up and down however I have NOT noticed this with any other gauges. All the time the 2HI is engaged, or it says it is. I am thinking that it is actually stuck in 4wd because my mileage has been significantly reduced recently. Did you ever resolve your problems with your vehicle?

Mine was the acutator cable. Not too hard to change just hard to find the part.

#88 of 115 95 GMC Jimmy not going into 4WD
Feb 09, 2010 (7:47 am)
I have a 1995 GMC Jimmy and had my transmission rebuilt a few months ago. Now that I need my 4wd, I notice that when I press the 4hi or lo button, I can hear/feel if shift into 4wd and the lights change, but the front wheels don't actually turn. I have read that this may be a vacuum hose problem. Can anyone tell me where to look for the problem or perhaps show me where to get a vacuum hose diagram. Thanks.

I am no expert on this can only give advise on my experence.
Under the battery you will find the actuator. It is vaccuum controled there is not much to this part and you should be able to see if it is working. You may have to start it. That can be done with jumper cables to the battery leads.
The problem I have is the cable from the acutator is frozen. Give it a little pull and it should move. If not that needs to be replaced.
Hope that helps.
