How do you get the warning chime to work in a 2005 chevrolet silverado?

i have a 2005 silverado 4.3 W/T and one day the warning chime just stoped working! its kind of an inconvience because i have the information screen on the dash that warns me of problems with the truck but i dont pay attention to it when im driving and the chime gets my attention! could it possibly be a blown fuse?
