Ok so i just bought an 04 ccsb lb7 push button 4x4. I've searched and searched and cant find anyone with the solution to my problem. My gauge cluster, hvac controls, 4x4 buttons and light switch have no back lights. They worked from the time i got it til now. About 2 weeks. The doors and stereo work just fine. The dimmer works too. Just wondering if anyone had any suggestions before i tear into it. Any help appreciated!
