Need to replace climate controls

[abatzis2@hotmail.com (Michael Abatzis)]

also, sounds like you have some screwed up vaccuum connections or a vaccuum 
leak somewhere if moving the selecter doesn't change air flow.  that stuff 
runs off a main vaccuum line from the engine; the control head redistributes 
the vaccuum to actuate valves and flaps and stuff.
