Welcome to the forum Joe.
I was reading on here recently that there is a small fan in the vicinity of the rear view mirror that moves air over a sensor to regulate your climate control. You should see 2 small vents on the overhead console (1 on either side of the sunroof switch if so equipped). If the fan is going bad, it makes a noise. Hope this helps.
