how do i fix the cruise control- just stopped working.

What is your question?

just recently, my cc light wont come on when i press cc button. now, it will come on sporatically, sometimes with the cc funtioning, sometimes w/ just the *light coming on, but the cc still wont work. is it a fuse? if i push the button several times, it has come on/other times, i do same n light wont come on. (*green cc symbol n light on dashboard that indicates cc has been activated) ty
