stereo problems
I have a 2003 suburban 1500. Radio (not Bose, no amp that I am aware of or can locate) and door chimes quit working as well as the driver door lock switch works occasionally. The latest issue was that stereo quit working (no display even),but the speakers were emitting a static and high-pitched sound continuously until I pulled the fuse. I have cleaned the grounds, battery is good, alternator is good, all fuses are good, radio has power for memory, but no power with ignition on or in the accessory position. Could it be GMLan, and where is it located? Are there any other relays/switches that could cause this as well? In my research I found that the 2003 chevy malibu had the same issue, but was a corrosion issue in the wire loom at the right rear door.
