That's clever, swapping the diverter flap vacuum hose for the center vent vacuum fitting.

Dave - Any idea when these crazy cars decide to open the diverter flap? Mine does so on occasion; I can tell by the noise. But I have no idea what criteria the pushbutton unit uses to trigger that decision.

One of us should probably post a listing of the vacuum hose color coding, and the vacuum ports on the seven-port valve. I'd do it now, but I don't have the shop manual handy on this computer. Sounds like this guys car may have the hoses switched around.
