check this topic http://www.4x4review.com/discussions2/topic.asp?TOPIC_ID=3908 then this one. http://www.4x4review.com/discussions2/topic.asp?TOPIC_ID=3916 Put the blazer on jack stand all the way around. Start it shift into 4wd do the front wheels move? If no check the vacume acuator under the batterie box. If it is split replace it. If it looks good, with out the moter running pull the vacume line off and blow into it. See if you hear air leaking some where. Mine was rubbing on the top of the moter toware the fire wall in the back. I spliced the vacume line and all was good.

P.S. I also used a hard cable for a while to pull the acuator but it kept coming lose so I fixed the vacume leak and put it back to stock.
