I recently lost the panel lights on 5 of my CC switch panels. The panels that went out include two nightstand panels, the bathroom panel, the galley panel and the passenger side panel next to the door. All of the switches in all five panels work but there are no back lights on any of them. I have tried to toggle the "panel light" button on each of the five panels to no avail. The other panels (overhead on dash and driver side) continue to have back lighting. Might these panel lights be fused on an ECC card? If so, does anybody have an idea of which card?
