Answer
Hi Dan, To help you out I need to know what model Cadillac you have. If you have the FWD Deville what you can do is unplug the climate control with the key off and then turn it on and see if the others light up. If they do then that panel is bad even though it is a differant panel. Key off plug the ccp in and unplug the fuel panel. Key on and see if the other lights up. Unplug the programmer which is behind the glovebox. It has a rod on top, black plastic box and 5 plastic tubes in a connector near the bottom. Turn the key on and the panels might light up. If so then replace the programmer.

       If the panels are still dark let me know what model you have and what happened when unplugging the panels and we'll go from there. Bill
