Trying to figure out where outside air gets into the heat A/C box. Openings at the back of the box go into the coach. The opening on top of the box go to the defrosters. There are no openings in the left, right, bottom, or front. Remember that this box is used only on 77, and 78 GMC's. Have photos if interested. Bob Dunahugh 78 Royale
