HELP Lights dim on instrument cluster
 

Hello All,

I have a 2000 Volvo s80 and the instrument cluster goes dim and the backlight for radio does as well. Last week, the fuel gauge was not reading at all, but now it is working. Sometimes the instrument cluster light are bright (usually in the mornings a few times a week), but 90% of the time it is dim. Has anyone had this issue. I have checked fuses already; I have even done an emissions test and checked codes. I am at a lost and don't want to replace cluster.
