You must have a bad vacumm leak check underneath the hood and follow the hoses leading to the intake manifold towards the firewall.

92 buick park ave only blows heat through defrost


Sounds like you might have blown the BM unit. As far as the vent selection goes, I worked on a Buick LeSabre a few years ago with the same kind of trouble. There is a vacuum distribution block down under the glove compartment that directs the route air goes. It is notoriously trouble. In my case the block was poorly formed. Sometimes the vacuum connections on the block are plugged, sometimes they crack or break off. Unless you are a full blown Mr Fixit you just need to replace the block.

The a.c. on my 98 park ave. only blows on defrost ior the floor setting. I can hear the blower running and a little air comes out when in the dash vent mode but not much , i can however feel it leaking...


It's most likely a vacuum line, look under your hood (close to the cowl panel) for a disconnected, cracked or broken vacuum line.

In some rear cases, it could be the vacuum switch (in dash). Or vacuum diaphragm (under dash).

Hope this helps you ???

Nothing blows out dash vents, but will blow out thru defrost nad floor vents on 1999 buick PA with dual auto air controls


check for a vacuum leak in the hose going to the heater controls. Goes from engine compartment, through firewall, into dash to control head. Also, has a vacuum storage canister under hood. When system fails, it defaults to defrost.
