Haha all wrong so far.
Its a cabin temperature aspirator/sensor.
Sometimes they tend to make noise when they are going bad, or get clogged with dust/dirt.
Try a can of compressed air (like the one for computer keyboards), or go to you nearest car detail shop and have them blow air into it for like 5 seconds, if the noise continues, buy a new one, its cheap.
So if I disconnect it cuz it was making a noise, would that explain why my interior temp gets really warm even when the heater is set to 60 Degrees?
