Are you referring to the ignition key or the switch on the control panel?

That's odd. The system vent doors are operated by engine vacuum and have nothing electrical, so I'm not sure how the key can play a role in it if the fan is already running. Have you checked for engine vacuum leaks or vacuum leaks under the dash for the HVAC system?
