Servo Unit
- Disconnect 4-way connector going to servo. See Fig 1 . Connect a test light between Blue/Red wire and ground. With ignition switch and cruise control switch in "ON" position, light should glow.
- Connect jumper wire between male and female terminals of Blue/Red wire. Attach test light to a good ground and check for power from the other 3 male terminals from servo. If there is no power, replace servo.
- Using an ohmmeter, connect one lead to ground. Connect other lead to Black wire terminal in 4-way connector of main harness. Meter should show continuity. If there is no continuity, repair ground circuit.
