These parts are usually damaged during removal rather than through use, and they are the ones most often left off a repair.
Panels are listed by position and by colour code where the manufacturer specifies one. Two panels that look identical in a photograph can differ by finish or by cutout for a switch the vehicle does not have, so the OEM number on the reverse side is the reliable identifier.
If you are replacing a cluster, a radio or a switch, check the condition of the surrounding panel first — a cracked bezel will rattle against the new component and read as a fresh fault.
