I've searched the forums to see if this is common, and turned up nothing. The analog gauges fail to illuminate when I turn on the headlights. Unlikely to be a bulb, because they all failed at the same time. I've already checked the fuses and they're all good. Any suggestions before I remove the entire cluster? The digital gauges light up correctly and the dimmer seems to function for the digital gauges just fine.

Thanks in advance,
Rich
