interior lighting (instrument panel illumination) on 1999 Chevrolet Tracker

At night my instrument panel will not light up. I checked the fuse but the fuse is still good. When i start up the vehicle usually the panel lights up when i hear a clicking sound but when i hear the clicking sound my clock gets dim and the instrument panel wont light up. What is my problem? Thank you
