Your blazer is equipped with a shift on the fly four wheel drive. That means that at speeds less than fifteen miles per hour you can shift into or out of four wheel drive by simply pushing the four wheel high button. If you wish to shift into four wheel low. Stop, put the transmission into park or neutral, and push the four wheel low button. Same procedure for shifting back out. Never shift into or out of four wheel low while moving. And be careful in four wheel low. At full throttle your still barely moving, you don't want to blow your engine up!

yea its not shifting again like before ? sounds like your transfer case solonoid has possably gone bad again .. these are a sometimes dont work item .. It is what shifts the transfer case into gear and it might be a little worn or weathered and not letting the switch kick it in gear all the way from the N position. thanks Jerry holler if you need more.

Hi ..i had the same same problem in my k3500,check 4x4 fuse first .if thats blown replace it if blows when you put in 4x4 go under the car and unplug the actuator at the front diff.go back in the cab and put another fuse in, shift into 4x4 if the fuse does not blow this time you will need a new actuator.
thats what happened with mine and now 4x4 is sweet.i thought mine worked to at the start until i got bogged and noticed my front wheels wernt turning.

I had this on my 2002 blazer (4wd 4dr 6cyl) about a year and a half ago. I found two things out. First, have to try shifting out of 4lo while in neutral with foot on the break. It seemed to work better while on a small incline (like waiting to put the boat into the water, not on the ramp but the somewhere shortly before ramp).
I finally decided to try to replace the neutral safety switch after much reading online. It worked and has worked perfectly since then. The shops I took it to told me to put in a whole new motor for about $600. I think I got the safety neutral switch for about 50ish. I have a pit in the garage so it was pretty easy to get under the truck to the transmission and remove the existing switch board. I then just attached the new one and plugged 'er in.
Hope it helps, good luck.
