Does the cruise still work?
If so, maybe the bulb just died.
Pop this thing out, it just kinda rotates out
(No screws or anything)
Take out these 4 screws
The cluster will come right out after that. Unplug the back, turn it around, and you'll see little black things where dash lights go. Rotate them and it will pull out with a bulb inside. Replace the bulb, put the black thing back in you you should be good to go.
If your refereing to the actual steering wheel buttons - they don't light up at all.
