Sorry for my delay.
When I first get in, I do not hear anything except the chimes etc. Once it is quiet, I tried several combinations of settings between temp, vent position, recir, and outside air. I hear actuation going between face, floor, and defrost vent settings. These noises seem to be coming from the top of the dash. I hear flap type noise switching from cold to hot, but not switching hot to cold. But I hear a flapping when switching back to hot. So I suppose I just don't hear the door switching position from hot to cold. This noise seems to be under the dash on the right side. But it is very quiet. I hear a flap noise when pressing the recirc button. This seems to be coming from deep in the system. I do not hear any noises when switching on or off the outside air button. When the a/c comes on I hear a very audible flap noise and the blower kicks up a bit.
As I mentioned, I tried every combination of settings which occurred to me. If you need more info, let me know.
Thank you.
