If its a digital dash not that this sounds good but smack the dash right in front of the steering wheel a few times and if it clears up or makes it do other things it needs a new instrument cluster.

Do you mean the backlighting for the buttons,or the digital readout,or both?If it is the backlighting,it should be just a bulb.It depends on a couple things of how easy it will be to replace the bulb.Where it is located,how the dashboard is built,and how much you know about access to the dash.It should be somewhat easy to get at since these are normally in the center or lower half of the dash and you should not have to take the whole thing out just to replace the bulb.Please let me know completely what is out on that panel.This should noway be just a fuse as it would cause more lights to go out.Greg
