Thermostat Issues Continued..............

[abatzis2 at hotmail.com (Michael Abatzis)]

the flap is also closed on max a/c mode. also, there's a vacuum line under 
the rain tray going to the flapper.  iirc, disconnecting it closes the flap 
(or opens it, don't remember which). never had this problem with the heat 
though.
