AC blower
#6
If your fan only runs on HI speed it's likely that the resistor in the AC plenum is bad. This is a common problem on Oldsmobiles through out the years. You can access the resistor from the engine bay, it's mounted in the AC box on the fire wall.
BTW, I merged your threads.

Yep. No vacuum means the air blows out the floor vents only.
Many times the hose to the vacuum reservoir on the firewall is disconnected.
This thread has a lot of pictures and info about a similar issue.
