This is the air intake for a small fan that draws cabin air across a thermister. I took mine out to test its function and discovered that the thermister was so covered in dust from years of use that it was not able to read the air temp properly. All I did was clean it with alcohol and my heat system was working!
Interesting. I have a sensor up by the rearview mirror that sticks out like a nipple.
