Base Cluster (Except Bonneville)

  1. Turn ignition off. Disconnect instrument cluster connector(s). Turn ignition on. Measure voltage between ground and instrument cluster connector Pink wire at terminal C7 (Eighty Eight) or terminal B1 (LeSabre). If battery voltage is not present, check Pink wire for an open circuit.
  2. If battery voltage is present, measure voltage between instrument cluster connector Pink wire at terminal C7 (Eighty Eight) or terminal B1 (LeSabre) and Black wire at connector terminals C6, C14 and D14 (Eighty Eight) or terminals B6 and B8 (LeSabre). If battery voltage is not present, check Black wire(s) for an open circuit.
  3. If battery voltage is present, measure voltage between instrument cluster connector C2 Pink wire at terminal C7 (Eighty Eight) or terminal B1 (LeSabre) and Black/White wire (Eighty Eight) or Blue/White wire (LeSabre) at connector terminals C9 and D9 (Eighty Eight) or terminal B2 (LeSabre). If battery voltage is not present, check Black/White or Blue/White wire for an open circuit.
  4. If battery voltage is present, measure voltage between ground and instrument cluster connector Pink wire at terminal C15 (Eighty Eight) or terminal B5 (LeSabre) and ground. If battery voltage is not present, check Pink wire for an open circuit.
  5. If battery voltage is present on LeSabre, go to step 6). If battery voltage is present on Eighty Eight, measure voltage between instrument cluster connector terminal C10 (Brown wire) and ground. If battery voltage is present, go to step 7). If battery voltage is not present, check Brown wire for an open circuit.
  6. Turn ignition off. Measure voltage between instrument cluster connector terminal A5 (Orange wire) and ground. If battery voltage is not present, check Orange wire for an open circuit.
  7. On all models, if battery voltage is present, check instrument cluster connector for good terminal contact at terminals C6, C7, C9, C10, C14, C15, D9, and D10 (Eighty Eight), or terminals A5, B1, B2, B5, B6, or B8 (LeSabre). If terminal contact is okay, replace instrument cluster.
