It doesn't matter what vent setting is selected, it only blows out of the defrost vent.

    yep! and it's probably on the pas. side fender area---use your ears (while it's running) listen for hissing sound. May have to open up soe of the corrugated tubing that covers a lot of wires and plastic multi colored vacuum tubes in that area. most likely hard plastic line NOT typical rubber vacuum hose.
