4x4 issues. Plan on going out tomorow

[ShowNgo4fun]

OK, I took a half day today at work so I could replace my front disc rotors and I found out that I have a much BIGGER problem. My 4x4 is not working. I have lifted the truck at all 4 wheels and the damn front wheels do not spin. It sounds like it is engaging and it sounds like it is putting a load on the engine but the front wheels do not turn with high or low. Any suggestions. I will stay up all night if I have to, I want to go wheeling tomorow at 8 AM!!!!

4wd actuator under the battery tray tends to be the culprit alot of times...

I think it may be called something else as well... I replaced mine and my 4wd is working like a champ.

I will check autozone and see if it fixes it. cross your fingers.

the main reason on cpi blazers why 4x4 wont work is because of the vacuum line on the back passenger side of the intake. it operates that vacuum actuator.
