My "Service 4WD" had been on, and no lights or anything on the panel. Pulled the fuse under the hood, and the one on the cabin (just to be sure) and let it reset. Plugged them back in and now everything works!
And before any snow gets here.

Weird. What's up with that?!
Apparently it's a software thing, from what I read. Just pulling and replacing the fuses makes the software "reset" but I'll eventually have to have it reprogrammed
I had to go to work at 2 AM today and noticed some de-icer had been applied to the road and there was a bit of icy sheen. I looked at my mirror display to check the temp and saw it was 35 degrees, but then it said "Ice" and went back to temp. It did this a few times then stopped and just displayed temp and there was no more ice on the road. I had no idea my Denali had this feature! I assume it used a combo of temp and traction control to diagnose the condition.

So as far as the Eagle Eyes, anyone rig some up in the rear caps of the Z71 rack facing backwards? I've seen the 3" light installed in them and dude on ebay does them for 85.00, but then I would have to change the bulbs, because he uses halogen lights. I assume the eagle eyes just surface mount, am I correct?

Nevermind. I'm gonna have to look at it again I think.
Made it a mile, and it came back on.

Sounds like one of the symptoms when my transfer case took a shit on me last year. Getting stuck in 4 lo without pushing the button, then throwing the SVC 4WD light and and the traction control turning itself on and off.

I'm really hoping it's not that. It SEEMS more like an electronics issue. Once the fuses rest it shifted into, drove, and out of 4wd without any problem. Then I drove a bit more and it told me to service 4wd, and it wouldn't go in anymore.
The fuses were both fine, the lights won't light up for either 4w Hi or 4Lo, and I'm hoping it's a switch problem. Either that or I think it could be the position senor motor in the transfer case.
Gonna take a deeper look than I was able to give it after work, and sitting around talking about it with a few beers.

That's exactly what was wrong with mine, encoder motor & sensor, also bent the encoder motor shift fork. $1100.00
