there is a tiny bulb behind the display. This is a common problem in the Pontiac radios, both of our Bonnies have had them go out, the dealer mechanic also told us that it was common. To take out the radio take a flat-tip screwdriver and pry the dash piece off. There are various connecting points, I started by the drivers door and worked my way across. After you unscrew the radio and take it out, the cover pops off and the bulb is in a brown holder that twists out. I think that it takes a 12V bulb. If you find a bulb that works post where you got it and what the p/n is, I have been unable to find a good replacement.
