Ok,
I checked under the hood as Mike suggested to make sure all vacuum
lines in place and secure. Everything appeared to be correct and in
place. Also determined that you could figure out if vacuum was
working by turning on blower & AC with out the engine running. I
identified 3 vacuum control units closest to driver under dash in a
line running up to top of dash. First one appears to switch between
hot and cold. The top two seem to work together with the center one
controlling the bi-level and floor flow. That one appears to have
almost no movement when you switch it back and forth so it is suspect
along with vacuum control unit at this point. I have also determined
that on all settings the largest volume of air is coming out the
defrost area .
The center unit has two vacuum lines running to it , the others only
have one. That's as far as got , need some else to do some switching
back and forth while I check lines. That's tonight's project, will
report back tomorrow

There should be one feed coming through the firewall then splitting
in the dash to feed each of those controls. You might want to invest
in a vac gauge or a vac pump/gauge combo like this.

note: I didn't pay anywhere near what they are asking. Local Steve's
tools had them for about $28 or so back when I got it.

You can use that for brake jobs, checking sensors, and removing
fluids like tranny or power steering as well, real handy tool to have.
