04' Silverado Brake lights and CC

I  have a 2004 Chevy Silverado 2500HD that has no brake lights and no cruise control.  All three brake lights are out and I'm not exactly sure if the Cruise control went out at the same time or earlier. I checked the fuses and they seem to be fine unless I'm missing one somewhere and I replaced the brake switch already twice.  I'm out of ideas and am stumped on where to try next.  Any help would be very appreciated.  Thanks.

do u have power and ground to ur stop lamp switch? u have a stop lamp fuse underhood block, veh stop fuse inside the i/p fuse block, and a veh chmsl on the i/p panel as well.
