Had the same problem in my boyfriend's Avenger. I took the cover off the back of the cruise control lever and found that the mounts were broken for the circuit board that the on/off button for the cruise control makes contact with. This caused the circuit board to be pushed back too far to make contact with the button. As a temporary fix I folded up a small piece of paper and put it behind the board to keep it pushed to the end of the lever and snapped the cover back on. Worked fine after that. Hope this helps!
