03 silverado 2500hd
Hello everyone. New to forums so please bear with me. I have a 2003 silverado 2500hd. Radio stopped working, still have display just no volume and no door chimes. I have already replaced the amp and nothing. Took it to the dealer they say no audio output need a new radio. So here's where the fun begins. My batteries took a dump and in the process of hooking up a jump box as soon as I connected it the radio and door chimes started to work. Replaced both batteries and no radio again.
