The A/C cars work differently than the non-A/C cars. Gary says it correctly...the air door on the pass side kick panel should open on Max A/C only, to recirculate the cooler inside air, and be closed any other time. The vent system on the A/C cars uses a different path from the cowl area. Thumbs Up

I have a PDF file on the '72 Chev HVAC systems, including Corvette, with wiring and vacuum diagrams, if you need it. It explains how the system is s'posed to work, and gives some troubleshooting info, too. It is a large file(for me) at over 3 mb, so if anyone wants a copy, make sure yer e-mail will accept it. Thumbs Up
I also have access to the same info other year models.

Gotcha.  Somebody tee you off or just didn't make the meetings anymore and couldn't justify the dues?

Just curious.
