I had a similar thing happen a few months ago. I figured a bulb had burned out and removed the central console and the climate control. Found out the bulbs are wired in -- i.e. they are not in sockets. Not having a whole lot of time I put everything back together, and lo -- the lights started working again and have continued to do so.
Perhaps there was a loose connection and unpluging and repluging (rebotting?) 'fixed' it. I'm waiting for them to go out again, but in the mean time I'm not going to fix it if it ain't broke.
It is pretty easy to remove the console and the units, took no more than an hour to remove and replace.
Best of luck
