Cruise Control: Testing and Inspection
1. Check for an open Cruise Fuse2. Check for vacuum leaks on the two vacuum lines attached to the Cruise Control Servo.
3. Check the Cruise cable connection from the Cruise Servo to the Adjuster Assembly. It should not bind or be too loose.
4. Check for proper terminal mating at connectors. Look for corrosion, bent terminals, etc.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check.
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
