Thanks everyone. I just went down to the garage to listen again and it is coming from both sides and seems to be coming from the headlight area. I sure have a lot of confidence in the service department now.
I bought a new BS Big Bend last week and I noticed that after shutting off the engine there is a humming noise coming from the engine compartment on the drivers side. I didn't think much about it until I noticed that the humming also starts whenever I open a door. I stopped at the service...
