I just bought a used 2009 Suburban LT from the dealership and noticed that there is a constant noise from the by the radio display even when the vehicle is off. Sounds like a fan or cd running. I confirmed there is no cd/dvd or navigation cd in as I took them both out.

I am concerned that this will bring my battery to a hault. I read elsewhere on this site that there will be noise from the unit when you open the door, but when I close the door and come back an hour later. It is still going on.

Any help would be appreciated!!!

 

moving your question out of "General" and into the Suburban section where it belongs ...
