2002 Chevrolet Astro Question: The AC won't blow out air. I found a loose vacuum hose that is worn out.

It is connected to a T connector by the AC unit. Where does the hose connect inside the vehicle?

    This hose connects to the vacuum switch that controls the a/c-defrost servo. If one of these vacuum lines is off or broken, you'll get defrost and nothing else. Common problem.
