I havent done a whole lot of research yet but when I turn my truck off the radio stays on like it used to but when I open the door the radio stays on, the dome lights come on but the radio doesnt shut off like its supposed to. Plus the door dinger stopped working, door can be open with key in and no dinger. This just started today. Got an 2007 silverado classic lbz. Any help would be awesome! Thanks!
