chevy silverado 2004 4x4?

[harleynhammer]

I have a 04 chevy silverado Z71. The 4 wheel drive and 2 wheel drive lights does not work. It wont go in 4 wheel drive. I have checked all the fuses, switches and actulator and they are not the problem either. Please let me know what you think it is?
I sorry I still dont understand? Could you tell me where in the dash to look? Thank You Again
