Yeah man same thing happened to me, and I have posi-loc so atleast I got it into 2lo so I could cruise around the neighbor hood attempting to get it out of LOW range. Ended up trying for 30minutes with no luck. moved on to the next problem( new to me blaze) which was swithing the batteries(previous owner put a crazy bolt into the side post battery) and after swithing batteries my truck popped back into 2hi on the first try. Coincidence, probably so, but thats just how it worked out for me.
