Troubleshooting Hints

CAUTION: Halogen bulbs contain a gas under pressure. Handling a bulb improperly could cause it to shatter into flying glass fragments. To help avoid personal injury:
^ Turn "OFF" the Headlamp/I/P Dimmer Switch and allow bulb to cool before changing bulbs. Leave the switch "OFF" until bulb change is complete.
^ Always wear eye protection when changing a halogen bulb.
^ Handle the bulb only by its base. Avoid touching the glass.
^ Do not drop or scratch the bulb. Keep moisture away.
^ Place the used bulb in the new bulb's carton and dispose of it properly.
^ Keep halogen bulbs out of reach of children.

1. Check suspect Fog Lamp Bulb for damaged or open filament.
2. Check the LH and RH Fog Lamp connectors to be sure the connector seals are not damaged or missing.
3. If one Fog Lamp does not work, check the bulb, connection and wires to the Fog Lamp.
4. If the Fog Lamps do not operate, check the TURN B/U Fuse.
5. If Head Lamps fail to operate or operate incorrectly, refer to Headlights. Headlamp
6. If High Beam Head Lamps and Fog Lamps fail to operate, check for an open in CKT 11.
^ 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 General Troubleshooting Procedures). Diagnostic Aids
^ Refer to System Diagnosis.
