So the heat and ac in my 97 Chevy Astro van only comes out the
defroster, and the bottom of the passenger side legroom area. Nothing
really comes out the vents. I know what the answer to this question is
already, I think. A broken vacuum line.

Where do I locate this vacuum line? Is this something that I can do
myself? I am fairly handy with tools (I changed my own alternator, do
periodic maintenence myself). Is there anything else that could be
causing this?

My aunt had a 96 S10 with the same problem. The vacuum leak for her was
right under the hood ... there was (at least on her truck) a vacuum
canister attached to the underside of the hood with a hose hanging off
it. Reattaching the hose solved the problem. Hopefully this helps you.
