Not your typical 4x4 problem

[Brute650i]

I am having a problem with my ESOF. The lights on dash change, the transfer case changes, but the vacuum pump doesn't change the a/c works like it should. The manual hub us easy to turn and will lock in when turned to lock instead of auto.

What could be the problem? Or maybe what is the sequence that the 4x4 goes through to lock the hubs?

Thanks for the help

Everything was hooked up like it was suppose to be as far as hoses/wires that I could see

Is the solenoid on the fender well switching? cause thats whats wrong with mine.

How can I tell if its working ?

its been awhile. If i remeber right its a 2 hose connector on the solenoid we took and unhooked the lines made sure it was getting vacuum to it and then hooked it up so only the vacuum supply line was on and then put it in 4x4 and i seen if it had vacuum at the other fitting mine didn't. hope that makes sence.

changed it and now its working but now the ac will blow out of defrost for the first 30 seconds if the truck has been turned off. Im suspecting vacuum leak but where is the best place to look and easiest way to fix.

Its blows out the defrost all the time when you first start it or only when its was in 4x4 when you shut it off and then restart?

Every time

If it wasn't doing it before you put the new soleniod on i would check the lines around that and makes sure they are all connected and in good shape. Other then that im not really sure
