My 97 Jeep tj wont go into 4 wheel high or low. When I pull the lever to shift into 4 wheel no lights come on and the linkage is hooked up but I can’t tell if it’s hooked up right. Nothing happeneds at all when I pull the lever
Post pictures of the linkage if you can. It's almost certainly a linkage issue, especially since you're saying nothing happens when you pull the lever.
In addition to what Chris said, consider replacing the linkage altogether with a cable shifter. It is much simpler, and also shifts much more smoothly. Far fewer moving parts to deal with.
I had all kinds of issues with my 4wd shifter. All of it came to an end when I installed the savvy cable shifter. It truly lives up to the hype. It really works!
