cant figure it out .. 2005 silverado, 5.3? liter v8 4wd crew cab, power everything .... driving along, anything on my instrument cluster that was on, goes off, .... including radio and a/c ... nearly anything than was off goes on ... door locks and windows are non-functional ... i thought i found it after checking ground on the battery .... was fine for about a week, now it is back ... no check engine light or obd codes ... my power steering was been wanky ( no assist when parked) so I was led to believe the evo might be going (short or ground causing gremlin) ... NO EVO! ... this thing is really getting to me ... any thoughts out there?
