It is most likely the cruise control amp that is located under the drivers side under dash panel.

What MB said. There is a rebuilder for these units out there somewhere.

firstly remove the intake crossover tube and look at the cruise control motor that is behind the injection pump, The small plastic linkage arm that moves the injection pump breaks and your cruise control never works.
