Cruise Control Servo

WARNING: This page is about a different car, the 1995 Eagle Vision, 1995 Dodge Intrepid, and 1995 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition switch and cruise control switch to ON position. Using a voltmeter, connect negative lead to a good chassis ground. Disconnect cruise control servo 4-pin connector. Check voltage on servo connector terminal No. 2 (Dark Blue/Red wire). If battery voltage is not present, go to next step. If battery voltage is present, go to step 7).
  2. Disconnect brakelight switch 6-pin connector. Check voltage on brakelight switch connector terminal No. 4 (Dark Blue/Red wire). If battery voltage is present, test brakelight switch. See BRAKELIGHT SWITCH  . Replace brakelight switch, if defective. If brakelight switch is okay, repair Dark Blue/Red wire between brakelight switch and cruise control servo. If battery voltage is not present, go to next step.
  3. Gain access to ON/CRUISE/OFF cruise control switch. Disconnect ON/CRUISE/OFF cruise control switch 2-pin connector. Check voltage on ON/CRUISE/OFF cruise control switch connector terminal No. 2 (White wire).
  4. If battery voltage is not present, go to step 6). If battery voltage is present, test ON/CRUISE/OFF cruise control switch. See CRUISE CONTROL SWITCHES  . Replace ON/CRUISE/OFF cruise control switch, if defective. If ON/CRUISE/OFF cruise control switch is okay, check for continuity across clockspring.
  5. If no continuity exists across clockspring, replace clockspring. If continuity exists across clockspring, repair Black/Light Green wire between clockspring and brakelight switch. Repeat steps 3) and 4) for cruise control SET/RESUME switch.
  6. Check voltage on input side of cruise control fuse. If battery voltage is not present, repair open in wire between ignition switch and cruise control fuse. If battery voltage is present, check cruise control fuse. Replace fuse if blown. If fuse is okay, repair wire between fuse and clockspring.
  7. Connect a jumper wire between cruise control servo connector terminal No. 2 (Dark Blue/Red wire) and cruise control servo terminal No. 2. With jumper wire connected, battery voltage should be present at servo's 3 remaining terminals. If battery voltage is present at servo's 3 remaining terminals, go to next step. If battery voltage is not present at servo's 3 remaining terminals, replace servo.
  8. Using an ohmmeter, connect one lead to good chassis ground. Connect remaining lead to servo connector terminal No. 1 (Black wire). If no continuity exists, repair open in Black wire. If continuity exists, test is complete.
