The "flapper valve" I meant is the one that fills the 1 1/2 or 2-inch hole that
DRAINS the HVAC well.   I didn't mean the cabin door that opens for
recirculation when the A/C is operating.   If that rubber DRAIN seal is
missing, you have a largish opening from right behind the engine and a little
above the exhaust piping.
