Cruise Control Servo: Testing and Inspection
1. Inspect fuse block module fuse 18; if satisfactory, place ignition switch in "ON" position and ensure battery voltage exists at fuse 18. Replace fuse
or repair open ignition switch circuit as necessary.
2. Place ignition and speed control switches in "ON" position, then connect negative lead of suitable voltmeter to chassis ground.

3. Disconnect servo 4-way connector then ensure approximate battery voltage exists at pin 2. If not, repair poor connections or adjust brake switch as
necessary.
4. Connect a suitable jumper wire between pin 2 of servo connector and pin 2 of servo, then ensure approximate battery voltage exists at remaining
three pins. If not, replace servo.
5. Place ignition switch in "OFF" position, then connect one lead of a suitable ohmmeter to body ground and touch other lead to pin 1 of servo
connector. If continuity is not indicated, repair ground circuit as necessary.
