2003 Accord,radio works fine,but the light does not come on,thus a very dark radio screen,fuses are all ok.Any idea what may be rwrong and how to resolve.

 

Might be there's a timing error with the wiring. I had dim lighting on my dash and speedometer gauge with my Accord and it really got worse in the colder months. The mechanic just adjusted some of the faulty lines and tightened any loose ends.
