Troubleshooting Hints - Gauges Cluster

Perform before beginning System Diagnosis
1. It is possible to have an open circuit to an indicator within the Cluster, though unlikely. Check circuits from suspect socket to connector terminals before replacing Cluster for an indicator problem.
2. If more than one gage or indicator are inoperative, check the appropriate fuse and ground before continuing.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (Refer to "Diagnostic Aids/General Troubleshooting Procedures.") Diagnostic Aids
