It's snowing like a mofo here in N.H., leaving the gym i decided to romp around in "auto 4wd" in the parking lot in my 2000 escalade, my service 4wd light came on after a few minutes, so i stopped messing around and went and got gas. Turned it back on and never came back on during the 10 mile drive home. Any clues? I've only had it for maybe 600-700 miles, haven't done any regular maintenance on it yet.
it just blinks when i try to put it in 4low, blinks then goes solid when i press the other 3 buttons, sometimes the light will disappear and come on randomly, confusing as hell and no clue how to fix it

Replace the switch I know as I had a friend who works at the collage I go to and his trucks transfer case went into neutral when his four wheel drive control switches failed he replaced the switch and didn't have a problem
My money is on the shift solionid next to the transfer case did one on a surburban last year same symptom. Not cheap either. I wanna say the part was around 200. Six pack job.
After 8 long months I finally got the new LM7 heart transplant. Its running rough because it hasnt been tuned yet and everything works except my 4wd...
I replaced the front solenoid and switch. All the lights on the switch blink once when I turn the key and that's it. I press and hold a button, nothing. I've yet to replace the rear diff solenoid but I have no clue why none if the lights come on.
I checked all the fuses. Pulled all 3 plugs to the T-case, they all have power or ground. It's getting tuned this week then I'll get a type 2 reader and figure it out. Sure is pissing me off though. The lights come on and go out when you turn on the ignition and that's it, and sometimes the lights don't even blink when you turn the key.

My buddy has a code reader that can read 4WD codes and he just told me the codes coming up are: C0308 - motor AB circuit low C0323 - t-case lock circuit low C0327 - encoder circuit low Time to do more research and call some dealerships.
I paid $115 for a new TCCM and now my 4WD works. Sort of. The 2HI light comes on and stay on, it shifts into AUTO 4WD, i can hear the actuator. I put it in 4HI but hear nothing, but says it's in 4HI (solid light on the switch) but will not go into 4LO, the light just blinks. Any thoughts?
Code that is coming up is C0323 - transfer case lock circuit low. I think it might be a bad encoder motor. Not quite sure, but at least the damn thing works now.

You never said exactly where the ground is, i need to know what both ends are attached to and the location of them. I got underneath it and looked for a ground coming off the rear t-case and saw nothing. Did the same thing to the front. There's no external ground from the t-cases to the frame.
