Air
Can anyone tell what to look for?
When I hit the blower switch for the heating or air, I get nothing. I have looked under the dash and the ducks seem to be connected, but I don't feel any flow. I can hear the fan blowing when I hit the switch. I guess I'm looking for something that isn't connected. Thanks for any help.

Pretty common issue. You need to look for the vacuume connections that move the dampers in the AC system. There should be a small vac line from the manifold that goes into the firewall and down to the selector switch, from there to all the duct operators and the like.
This is a vac line schematic for my 81, its pretty typical
