Looking for some knowledge
 

Hey guys and gals I have a 2001 chevy blazer and my 4 wheel drive keeps kicking out. I've changed vacuum lines and the actuator changed the buttons on the dash just wondering where is the next best place to go from here

Thanks

more details.. What do you mean by "kicking out"

When your driving it will shift back into 2wd

Sounds like you are still having a vac issue if it is shifting back into 2wd, which would indicate it is not holding vacuum
