armored a6

Hi, hope I can get some help, my problem is that my cluster including the air conditioning unit seems to have a poor illumination in daytime (at night they read just fine), I`ve also noticed that my radio unit adjusts to the amount of light via a sensor located on the radio itself ,that makes the radio(but only the radio) brighter at day so it can be read better, so I`m wondering if the cluster has another photo sensor, where is it???, I`ve just tried to replace the photosensor located in the dash near to the windshield but I don`t know if that would solve the issue, any ideas?? do you know if the cluster has another sensor?? where is it??? it can be fixed or replaced????, does the dash sensor has something to do with the cluster illumination?? what it is for??? thanks for your time I really appreciate it
