He is right, that is a little fan and a sensor for the driver temperature for the air conditioning system. That is no microphone.

Mine as well made noise, so i blew with pressurized air through the grid, since then there has been silence.

I'm not sure what's supposed to happen, but mine seems to run all the time. If I'm in the truck with the key on "run", but the engine not running (like checking for codes), I can hear it softly running.
