I'm chasing my AC gremlins and have noticed that the center vent releases hot air even when I have all the control switches to OFF. Does this mean the center pod is leaking? When I turn on the AC to high or low, the air does come out of the center vent (still hot though but is probably related to the compressor/freon level -- but that's another post), so it looks like the pod is opening the flap. Is it not closing all the way? But I don't understand why the heat will still flow through the system when I have the switches to OFF.

(this is the ACCII; no monovalve; servo and amplifier appear to be working; compressor clutch works)

Thanks,
bigmaq
