Answers :

One of my vehicles is actually a 2000 blazer and i had that same problem believe it or not. you should check all the connections to the brain of the 4wd. take off the passenger side right side kick panel. the kick pannel is that piece on the side right there next to the door. take that off and you will see a grey box. pull the wires out and look at the ends. i cleaned mine out with a q tip because there was crud in one of them which screws things up. if that doesnt fix it you may need a new one. they can be really expensive from a dealer so i went to a wrecking yard and pulled one out of another blazer and it only cost $20. it works fine now :) i hope that helps.
