1996 Chevy Blazer LT. In the process of installing new engine and rebuilding the transmission. Its been awhile since I removed the engine, transfer case etc. so I dont clearly remember where the transfer case gets its vacuum from. I am talking about the series of hoses that go back to the transfer case. I can see where they hook to the transfer case but where does it get hooked to up in the engine compartment as the vacuum supply?

 

Forgot to mention that this is a push button 4 wheel drive.

Thanks for any and all help

 

On my 95, there is a port that comes off the back of the intake manifold that supplies the vacuum to the 4wd. I don't know if they changed them on the 96. I believe they did as yours has a different looking intake.
