Cruise control failure could be a failure electrically or mechanical. Have you a Service Engine Soon/Check Engine Light on. If so a scan tool is required to retrieve the trouble codes from the on board computer in your car. Look on Autozone's website once you register they have a lot of workshop manuals for popular cars on line for free.

Hello ,, the cruise control will not turn on the check engine ligt, because it is not an emmission related fault, however there might be a code stored in the body control module that might help in the diagnosis.. the most simpliest problem to check for , is make sure all of your brake lights work, a burned out bulb will cause cruise not to work
