Dash Lights on 1998 Oldsmobile 88

I am having a dash light problem on my 1998 88. The dash lights will be very dim (too low to make out the instrument readings) at night and cannot be seen in the daytime. That also causes the radio and odometer to not display. I thought it was the daylight sensor but checked it and it was fine. There is something called a light control module under the dash to the right of the steering wheel. I have read that the module may be the problem and am looking for one now. The little information I could find said something about the lights being florescent and that the module was used to control their brightness. Never heard that before and so am still without dash lights. I know my fuses are good. I am hoping that some of the real experts on this site can give us some advice on this, Please.
