Turn on AC on auto, goes into recirc mode and cabin air flap does not open so no air circulation
Both the cabin and outside air flaps are closed, Codes 00457, 00716, 01274, 01229 Flap Motors are new
When problem began the inside flap would modulate and open and then close
When I remove the cabin flap motor and prop the flap open Ac works fine

We don't attach them. They're just text. Copy & Paste the whole thing into a post, preferably between CODE tags, as explained here:
