Troubleshooting Hints - Gauges Cluster
1. Check CLSTR Fuse. If open, check CKT 541 for short to ground.2. Check INDIC Fuse. If open, check CKT 39 for short to ground.
3. Check any inoperative indicator bulb.
4. Make sure grounds G113, G201 and G203 are clean and tight.
^ Check for a broken (or partially broken) wire inside of the insulation which could case 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.
