    ac blowing out through floor vents

    My 98 z28 ac seems to only want to blow through the floor vent setting. I'm thinking its a vacum line. Am I right? If so which one is it?

    Sounds right. The line is behind the intake. You gotta feel for it.

    On the passanger side.

    Manifold. The best way for me to describe it is...it is an "F" shape plug. You have a vaccum hose plugged in the bottom, the top, and the middle one ( on my car) was the one that came loose and controlled where the a/c came out.
