Hi there.

On these W123's, if the cruise engages but the speed is erratic and fluctuates, the actuator is usually the culprit. If it doesn't engage at all, then the amplifier is the most likely cause.

Most long time owners opt to install more reliable cheaper alternative cruise control kits such as the Audiovox CCS-100 and the Rostra(###) ###-####
