You said you mounted it differerntly then Tom? Can you post a picture?

I have a 75, and I just cant put my thoughts around the max air vent. Mine has a large floor ioening that I would consiter the recirc opening.

Sometime before next spring I am really going to have to test and learn what the vacuum flapper vents are supposed to do, and start there. I still plan on adding a aux evaporator, but having the oem working better would allow more ease and obviously help heat/defrost side.

I also wonder if maybe there are mouse nests one cannot see. I know in a 91 f-150 they can clog up vents that you never knew existed. I have had the front of my hvac box opened in the past year and cleaned things up and replaced the gasket on the heat/ac flapper.
