Firstl, thank you for your service to our country. Secondly, go down to Radio Shack and get a little volt meter (maybe 5 bucks) so you can check and see if power is flowing to the cruise control switch. If you know the fuse location, check and see if power is present at the terminals. Maybe purchase a repair manual that shows a schematic so you can trace the wiring. Maybe a mouse or nosey neighbor has been poking around or someone took it "offroad". Who knows. A wire could have been ripped out of its plug. Good luck my man.
