Due to the complexity of the speed control system, it should be repaired by a dealer service department. However, a home mechanic can perform simple checks on wiring and vacuum connections for minor damage that can be easily repaired. These checks include:
- Inspect the speed control system actuating switches for broken wires and loose contacts.
- System fuse check
- The speed control system operates on a vacuum, so it is critical that all vacuum switches, hoses and connections work reliably. Check the hoses in the engine compartment for loose connections, cracks, or obvious vacuum leaks.
