I assume I have a kinked or disconnected vacuum hose on my son's EF Futura but any ideas on where to look first and before pulling the dash would be appreciated.

When on anything but face level it blows out both floor and demister; even when on bi-level (face and feet) setting. Face level works fine on its own. I also I don't hear the required hissing sound when I first switch to bi-level or feet and demist (i.e no hiss on the top position or bottom 2 of the rortay dial) which suggests there is a disconnected or kinked hose somewhere.

Interestingly this car, although it has factory fitted air, only has the seven (7) rather than eight (8) vacuum hoses entering the socket on the heater case. The factory manual shows eight for air conditioned cars and seven for non-air conditioned cars. The connector for the extra hose (black cabin temp vacuum supply) is a blind fitting so it was clearly never meant to be there either. I gather though that it isn't unusual for this hose not to be fitted.
