VW Golf speakers humming
 

Hello, I have an intermittent humming issue when my radio is on. There is a background humming on the speakers. When I open the driver's side or passenger's side front doors the humming will stop. But the humming will resume once I close the door, and the car interior light will remain on unless I manually turn it off.

I would have thought it was a loose speaker wiring connection, except that it is intermittent, and the doors and interior light are confounding.

Any advice would be helpful

Thanks
