Buick Century Cruise Control Servo Parts Questions & Experts Answers
- Q: What Are the Cruise Control Systems Components and Operation of Cruise Control Module,Cruise Control Servo and Cruise Control Switch for Buick Century and Regal?A: Cruise control maintains a set vehicle speed in normal driving conditions. It mainly uses vacuum to run a throttle servo, overseen by the Cruise Control Module (CCM). Features include cruise, coast, resume/accelerate, and "tap up/down" speed adjustments. Activation typically starts above 25 mph (40 kph). Key components are mode switches, CCM, servo unit, Vehicle Speed Sensor (VSS), vacuum supply, release switches, and harnesses. The system retains vacuum at the set position, with the controller managing three vehicle/system states. Components include the vacuum servo, EMC Controller/Actuator, Electronic Module, and VSS, supplemented by a Vacuum Accumulator for consistent performance.
