I'm no expert, but I did spend three days on my back hacking my old blend door out and putting my new, aluminum blend door back in. But I'm thinking there is some sort of blend door-like component that cycles where the other air flows too. Like to the floor, dash or windshield.

Maybe you've ID'd a whole new blend door issue! I hope not but it must be that or the actuator motor(s).
