Does the cruise control function normally? If it does the on/off switch for the cruise may be bad causing the light to stick on all the time.
If the cruise control doesn't work then you'll need access to full function scan tool to find fault codes if any. It would probably be better to have a professional diagnose the cruise control because there are several components that cause the cruise control not to function.
Thanks for the question.
