I have a 2001 Blazer 4x4 and put it in 4wd this morning in the snow. When I tried to switch it back to 2wd it wouldn't switch back. Seems to be stuck. Any thoughts???

TRY SETTING THE TIRE PRESSURE CORRECTLY IF THATS NOT IT, YOUR CABLE FROM THE FRONT DIFF TO THE VAC, UNDER NEATH YOUR BATTERY, MAY BE ROTTED... U HAVE A LEAKY BATTERY?

Thanks Grkblazer. I finally got it into 2Hi by putting the shifter in neutral. Then it wouldnt switch back into 4 Hi. So, I disconnected the battery for a few minutes and that worked. Thanks for the info though, because I think I only reset the computer, and probably didn't fix the real problem. I'll check out the other parts and see what caused it...
