    i have a 05 2500 gmc and my back up lamps arent working. I checked the fuse under the hood and it is not blown. I also checked the bulbs and they are fine. Any ideas on what is the problem?

    Check for corrosion in the lamp sockets. Possibly a bad ground as well.

    Might be the shifter cable adjustment?
