2007 Saturn Aura XR instrumnet cluster issue.

Recently I have noticed that the lighted needles in the instrument cluster do not light up. It does not mater if it is day or night, if the lights are on manual or auto, or if the dimmer for the cluster is all the way up or down. All of the other instrument cluster lights and functions are working properly.

This may be something as simple as a fuse or as complex as a PC board issue. I need some help troubleshooting and diagnosing the problem.

Thanks in advance…
