I have a 96 blazer. 4.3 vortec v6

Ok, I attached the vacuum hose that you see in pic 1 to a different source of vacuum and I finally got heat through my dash vents (instead of just on my feet and at the window defroster) but that was just a test.

Look at the first pic in the attached files....Anybody know where that hose connects to?

Now look at the second pic in the attached files....It's of the same hose but just a little further down the hose you see a T- Fitting without any hoses connected to the 90 degree connector. Anybody knows where that is supposed to go?

Now here is my theory on how it connects....See pic 3 and tell me if im right or wrong.

 

It should go to the vac storage canister. It is a round ball looking thing in that area. I believe it is attached to the hood above the booster

 

Awesome....but do you know if it's supposed to hook up the way i explained?

That T connector that I want to hook the broken off hose to runs to the vacuum canister/ball

 

Not sure without seeing. Look at the vac diagram on the hood.

 

I wish I had one.... lol

If I take some more pictures of that vacuum ball, the lines that run off, and the line that I am trying to fugire out where it goes, do you think you will be able to tell?

I will double check on that vacuum diagram tomorrow.

 

Could not hurt to try. I can not believe no one here has a s-10 to go look and let you know.
