Need help with cabin heat ASAP (solved for now)

I thought he was referring to the dual Max AC duct as he has a 76. The recirc door on 77-78 would be sucking not a source of cold draft. Not sure of
the rec door location on 76 but might be more pass side.

I kinda think I'm experiencing the same thing. Is there a write up or photo power point on how to bypass this? Was hoping to place a inkine gate valve
to use for heating in the winter but block off hot water from core for air conditioning in thr summer?

Nope, not Dual Max AC, just a vent opening. I wonder if recirc valve or door is stuck open and I'm getting a blow by from the fan going in the
direction opposite to what was intended. Plan on sticking a flashlight in both directions today to explore it.
