So I have a p38 and I’m having a electrical issue that only affect the a/c, radio, and cigarette lighter. I’ve replaced both the stereo and climate control, along with the fuses and fuse box and but doesn’t solve the problem. They both get power which confuses me more. The back story is that the person who owned it before me had dropped a penny in the cigarette lighter and that’s what caused the problem. I’ve suspected a burnt cable but haven’t found any signs or evidence of that.
