Does your speedo needle fluctuate? The cruise control speed pickup is in the back of the speedo head. If your speedo is fluctuating then your cruise control will also.

The cruise control stalk isn't hard to replace. Remove your steering wheel and then you'll see the remainder of the trims and screws from there.
