Instrument Cluster

  1. Check fuses located in instrument panel fuse block. If more than one gauge is malfunctioning, check common power and ground inputs. See WIRING DIAGRAMS  .
  2. Before replacing instrument cluster due to an indicator problem, check for an open circuit to indicator within instrument cluster (from suspect socket to connector terminals).
  3. Before replacing any components, check for poor terminal contacts at component and associated harness connectors. Check for broken (or partially broken) wire inside of insulation which could cause system failure but pass a continuity/voltage check. Check for proper installation of aftermarket equipment.
