car audio

I have a 99 chevy malibu and recently have had to have the alternator changed. when the delership changed the alternator the dealership said the stereo was not there job and we have to go to the chevy dealership and charge me $30 for it so if anyone can help me with the codes that would make me very happy. It is a delco radio in a 99 chevy malibu...
