GMT800: "SERVICE 4WD" message, unreponsive 2WD button

Damn, I guess servicing these 4x4's is one reason I've never owned one. Hope you get it figured out Kyle.

This is not typical, Jeff. Not part of normal service, either.

And that is why I like a manual transfer case.

Yeesh. I do believe the Avalanche is becoming a bigger money pit that my 95.

Did something else go wrong?

Just a bunch of little problems that are irritating nonetheless. TPM sensor, torsion bar crossmember bushings, fuel pressure regulator, etc.

Sorry to hear that. So far my 2001 hasn't given me too many problems yet. Just the water pump and Ac compressor so far. And then all the normal stuff lime brakes and belts and battery and all.

Sounds like some higher mileage quirks, it will stop man.

Hey Penguin, you were right all along. Apparently, bad solder joints in the switch is still an issue for the 03+ trucks. I cracked the switch open today, and all but about two of the joints had cracks.

Glad you got it figured out, man
