It sounds like a problem with the BCM itself. The next logical first step would be to get it scanned with a Tech 2 for any Body error codes and see if that points you towards a solid solution.
But doesn't it make sense, even if they're two different circuits, they're tied together somehow. When you twist the headlight knob to dim and brighten the display, the odometer, the lighted dash and radio all get dimmer and brighter at the same time... so they have to be tied together somehow.
