I was not able to utilize my 4x4 until today. After reading some of the posts on here I located the vacuum line and it was not connected. I had the blinking light originally and now when I push the 4 hi or 4 lo it engages. Problem now is when i go to turn around or even take a turn very slow it is hopping/slipping. It seems to be fine going straight just when reversing or turning very slowly does it do this. My blazer is a 2000 4.3L. Any suggestions would be greatly appreciated. I am brand new to this forum and am very thankful to this group for the
help thus far.

 

It sounds almost like the transfer case is still engaged. Check the transfer case fluid. If it hasn't been changed for a while, change it and make sure you use the autotrak 2 fluid which is blue in colour.
The owners' manual indicated the wrong fluid as the updated fluid came out after the manual was printed.
