Instrument Cluster Backlight Issue

I have a 996 TT with an instrument cluster that does not backlight without the lights on.  The cluster backlights fine and dims with the headlights on but the cluster does not illuminate when the lights are off.  According to the Owners manual, the gauges are supposed to back light based on the ambient light sensor located in the tach near the 8k rpm indicator.  Since the instrument back lights do work with the lights on that is guiding me towards the light sensor.  Does anyone have any experience with this issue and were you able to repair it?

Do not double post, it is against the forum rules you agreed to when you joined.
