The power for the climate control lighting runs through the instrument cluster. Is your instrument cluster lit?

If none of the selections for the climate controls are working either, the connector plug on the left side of the climate control might have popped off?

I get mine out by removing the glove box. You might not have to do this. Then remove the wood trim covering the fan switch. Remove the two screws on each side and push the fan switch out of the way. There are two clips, one on each side, that lock the climate control in the center dash. Lift the tabs and slide it out. I belive the plug on the left is the one we are discussing.
