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.

There is an electric actuator at the transfer case, more than likely that is the problem. And could be the connection to it also.
#92 of 115 1999 Chevy Blazer Transfer Case
Oct 01, 2010 (7:58 pm)
Recently I changed the chain in my transfer case. I re-installed it and it was stuck in 4 low it would not ingage into 2 whl dr or 4 high So I took it apart again and noticed the forks were pretty tight, after awhile of messing with the 2 bolts that hold the forks i loosend it up. Put it back together again and now it is stuck in 4 high and well not ingage into any other gear. Both times I took the transfer case out I had the vehicle in park, I was told the buttons on my dash had to be in neutral. Whats Wrong:(
#93 of 115 2000 Jimmy stuck in 4hi
Nov 15, 2010 (8:06 pm)
My Jimmy has this tendency to stick in 4hi. A couple of times it fixed itself when in a warm garage, but it did it again in July. It clicks and something under the car (t-case motor) purrs like it is working or trying to but still in 4hi. We fixed it with a hair dryer but now it is stuck again and I can't get it back to 2hi. I just bought a transfer case motor, took off the old one. Getting it off and the drive shaft out of the way was not a big problem. Before I put on the new one - can I take the old one somewhere to get it checked out? The new one says it comes in 2hi mode and I need to set the transfer case to match. According to the new motor I AM in 2 hi because the tab matches the slot. So why am I really in 4hi? I just don't want to pay for a part I don't need.
#94 of 115 2000 blazer np8 transfer case stays in Auto 4WD
Nov 22, 2010 (12:23 am)
Hey guys. Wonder if anyone can help with this. I have the 4-button (with Auto 4wd) transfer case and it always stays in auto. It shifts through 2wd high, 4wd high and 4wd low but always ends up going back to Auto 4wd all by itself. I've had it to 2 different transmission places and have replaced 1) the buttons 2) the encoder 3) the tccm module (actually swapped with a buddy's blazer - the upgraded module, not the original hi failure one). Nothing has helped. Has anyone heard of this problem before? Any help would be greatly appreciated. Thanks in advance.
