Please fill out the following to ask a question. MAKE:Chevy MODEL:Silverdao 1500 4wd Crew cab YEAR:2012 MILES:48,000 ENGINE:5.3 LC9 DESCRIBE ISSUE.... My truck has a weird intermittent humming noise coming from either inside or behind the dashboard area? It only happens while driving around town at speeds between 15-45 mph. The sound goes away as soon as I let go off the pedal or whenever I step on the brakes and then comes back as soon I press on the gas pedal again. I've tried disconnecting both the Stereo and AC control panel and it still happens regardless. I've read about Hub bearings and worn out Brake pads and shoe but somehow I am pretty convinced that it's something else. Most of the times it sounds as if it's coming from somewhere behind the Radio or towards behind the glove compartment area. Any advise or suggestions is greatly appreciated.
