    08 Taurus X, heat will come out of the dash vents or defrost but will not come out of floor vents. Ideas?

    Welcome to the FFO!

    Most HVAC systems direct air flow based on doors. The doors move and redirects air flow based on input from the operator selection at the instrument cluster. More often than not the door is vacuum operated. If the system has a vacuum leak that is sufficient the door defaults to defrost.

    If you are getting flow that changes from vents to defrost based on YOUR selection on the controls, you do NOT have a vacuum leak. If the system does not change no matter what you do it is very likely you have a vacuum leak.

    If you have a vacuum leak it is a matter of following vacuum lines and finding a connection disconnected, line split or crimped.
