Question about 1998 Buick Park Avenue
Fan runs but air doesn't blow from dash vents. only blows into defrost
It sounds like the air distribution door motor is bad. If you turn the fan speed to low with the ignition on/engine off and try to change the mode to something other than defrost, you should faintly hear a motor running. If its making clicking noises, then it is most likely stripped. This is a fairly common problem with mode door motors. It will have one on each temp door for the dual climate control as well. Those ones usually last longer.

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 ???
