Hi, a friend's '08 with about 60k on it has been having sporadic issues with the cruise control for a few months, now it's no longer working at all. The on/off switch seems to be operating, but nothing happens when the set button is pressed. I'm assuming the sporadic nature signals a short, but any ideas where? The brake lights seem to function normally, and he hasn't complained about any other issues that I'm aware of. Thanks for any input.
