adjust your temp knob. Mine started doing the same thing some months ago.
I adjusted the knob off of the coldest setting and the noise stopped. Was not an issue until I got back to Tucson and its triple digits now, Pretty sure it is a air flow flapper to coin my own words for the parts. Have not had the inclination to start taking the dash apart to get to the problem. It is not that hot yet.
