What always worked for me on the older Yukons was to get on some gravel road as hard surface just made it worse, then roll backwards in reverse slowly while still moving shift into neutral and then take it out of 4Lo. Might have to do it more than once but it always worked.

Agreed.
The front wheels need to be able to “slip” a bit on wet roads or loose gravel when turning.

At a complete stop put tranny in neutral. Then put Tcase into neutral. Then shift Tcase to 2wd,4wd HI or Auto 2wd. And dont ever think about racing the SUV in 4wd LO unless you want to pick the pieces of your Tcase off the road. 4wd LO makes a YUGE amount of torque at the wheels(At low vehicle speed), it is not designed for any form of normal use driving.
I have a 2003 yukon with this problem occurring intermittently. The first and most simple way to get it out was turning it off, then back on, then go into neutral and HOLD the 2wd button for 10 seconds, even if it seems like nothing is changing, hold it down. If nothing after 10 sec changed the only other thing that worked for me was popp8ng the dash cover/ face off off, removing the 4wd switch. Unplug the harnesses from the switch and plugging them back in.
I've had this problem for a while and almost always holding the 2wd button has worked, even when it seemed like it wasn't doing anything. After 10 seconds it would "klunk" out if 4 Lo. I learned that from a random comment on a forum somewhere.
Hopefully this helps. I just had this issue a few days ago and tried multiple things. Pulled fuses, disconnected battery, but the only thing that worked was removing the switch, pushing the wires into the connectors (just in case) and putting it back together. Once I turned the car back on I was able to go back into 2wd.
Usually I dont lose the lights on the switch, but I did the last time it got stuck. If I have lights, normally holding the 2wd button worked.
I should have made it more clear. Mine randomly will go into 4wd on its own. I don't keep it on auto. It hasn't done it will driving. Sometimes after I start it up, it will randomly be in 4lo or 4 hi and I always have to turn it off, then on, then hold the 2wd button for way longer than you would think you would need to. The last issue I had was different. No lights in the switch.
