This sounds like a vacuum leak from the AC selector switch. Remember, that switch
selects both electrical connections and vacuum routes, regardless of whether you have air
conditioning or not. Change positions of the switch and jiggle it. If the sound changes
you've found your culprit. But even if the sound doesn't change the problem could be the
vacuum inlet (actually air outlet) line.

The DML backissues feature many discussions of repairs to this system.
