We have a hooting noise when heat is selected to the cabin. Sounds like air flow noise ahead of the firewall. Anybody else encounter this phenomenum?

If I had to guess, it sounds like there is enough velocity in the duct to whistle between some openings. Might also be as simple as a piece of tape or a tail on the SCAT that is acting like a reed.
