Looks like the system just froze up..
I parked it in the garage overnight, and everything worked fine in the morning.
Should the 4 wheel drive system in these trucks be freezing up so easily?
It was outside for maybe 4 hours in -17 the service 4 wheel drive light came on.
just got this message come up on my 08 with 115k
It's still under warranty, looks like it will have to go see the dr tomorrow
edit- this is why I was much happier with the 4x4 system in my GMT-800, I drove the piss out of it.. and was a little neglegant on maintenance since it was pretty old, and the 4x4 would always work without a problem.
My father had alot of issues with the AWD in his 03 trailblazer
