Mine didn't work when I picked it up. I didn't think that much of it, untill I noticed that the brake lights didn't work either. I think it was a fuse issue.
Thanks for the input guys! No my foot wasn't on the clutch pedal.
I went to a local car show tonight and the cruise worked perfect all the way there and all the way home. I don't know what the problem was earlier today.
Spanked an F-body on the way home ... silly chevy guys
