If you own an older Subaru car, the cruise control light could be flashing due to a faulty mechanical component. In older models, the cruise control system has a cable, connecting the throttle to an air actuator, which regulates the cable to keep the vehicle at the set speed settings. The vehicle speed sensor is mounted at the tail end of your transmission, and if it malfunctions, the cruise control light will start blinking on the dashboard. The speed sensor is needed to ensure that the speedometer and the odometer work correctly, and without it, the cruise control system will be affected.
