I have an 07 TB SS, what is the speaker looking thing on the door post between the front and rear drivers side doors. It is making a humming noise and is driving me crazy. Hogen

Onstar microphone is in the overhead console, would not work very well behind the driver's head.

There is a small fan in there to send cabin air past the interior temp. sender for the HVAC system.

So I'm not really clear on the answer... Is it a cabin fan ? Mine is now making static noises (2005 Envoy XUV SLT). Seems like it's making them even when key is taken out of ignition. Is this going to kill the battery? Should I pull a fuse?

It runs for a little while, mine does it everyday, haven't had a battery issue. It is a small fan for the climate control.
