Usually indicates a communications malfunction between the body control module, fuel data center, and the climate control panel. Do you have a digital instrument cluster, and is it still displaying speed info?

Its either one of the 2 heads or the bcm. Remove the l and r info panels, but leave them pluged in. Unplug the fuel center does the a/c panel lite?If no plug it back in and unplug the a/c panel does the fuel panel lite up?If still nothing you will have to replace the bcm.
