Hey folks, Just bought a 97 chevy and its been giving me some problems with the radio. It seems this is a common problem where it still has power and functions but no sound. The speakers are all brand new, as well as gone through two aftermarket head units so they are not the problem either. I have read up on this and apprently there is either a control box by the gas pedal or silver box by the ash tray. Just wondering if there is a place to purchase these or a way to bypass these as I hav no idea what I am looking for dont want to go tearing out random things. Thanks!
