Heat is Acting Strange
Background: 94 Sport with a busted vacumn reservoir, hose is plugged, no vacumn leak.
It blows hot air in vent and in defrost. But when I put it on heat it stops blowing any air at all.
Any ideas?
Not really an issue just super annoying.

Sounds like a door issue in the heating system.
Under the passenger side dash, with the engine running, heat on and all, observe the movement of things while you slide the upper lever of the dash control back and forth.
