The only thing under vacuum control in the 04 HVAC system is the mode door. If you are seeing problems with defrost vs vent vs floor, a vacuum leak would be suspected. More likely, the problem is with the blend door which is under computer/DC motor control. HeaterTreater has found the Ford design error in the construction of the system and built replacement hardware to fix the problem. Check the Tech section on the web site for a full explanation of the problem, symptoms, and DIY fix.
