cause of buzzing from dash

[chydog]

2010 GMC all terrain CC - sounds like buzzing from center of dash, maybe a blender motor ?

 

firm smack on center dash causes it to stop, still goes with stereo and auto-climate set to off and will continue with engine turned off and key removed until you open the door and interrupt the Random accessory power ??

 

anybody experienced this ?? lmk - thanx in advance

 

I have a short video but its 30mb and I cannot post it

I had a 2011 before I traded it with the Navigation system and I had a buzzing sound in that truck but it sounded like the disc drive spinning to me so I didn't worry about it a whole lot. No other functions of the truck was compromised and the only time I heard it was right after I turned the truck off. Never really thought about it until now but I always kept a CD in the drive that I never listened too unless I couldn't get anything on the radio or was tired of listening to the music on my phone. Do you have a CD in the CD Drive by chance?
