Cruise control will not turn on?

The short of it is, ever since I had the serpentine belt replaced, my cruise control doesn't turn on anymore. Is there something that could have come unhooked/been disconnected during that fix that I can hook back up? It would be so very wonderful to be able to use cruise control again. Maybe under the car? Maybe under the seats? Near the belt that was replaced? Is the connection for the cruise control anywhere near any place the serpentine belt has to be disconnected from or to? Does the cruise control have ANY relation in any way to the belt?
thank you
