Just a thought. If the body control module (BCM) were indeed the culprit, would the symptoms be isolated to just two inoperative gauges on the instrument cluster? On a totally different vehicle, the dial on the tachometer started acting erratically by moving from side-to-side. The problem was solved after replacing the entire instrument cluster with a used unit and the issue never occurred again. Again, this is just a thought.
