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 Headlamp/I/P Dimmer 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 LO and HI Beam Lamps for damage to the filament or bulb.
2. Check Fusible Link Y for damage.
3. If a LO or HI Beam Lamp has been found damaged and an unusually high amount of moisture is noticeable in the Headlamp Capsule, check the Vent Tube and Drain Tube for restriction. Small amounts of moisture are normally found in the Headlamp Capsule, however, excessive moisture can damage the lamps.
4. Check die LH and RH Headlamp Capsule connectors to be sure the connector seal is not damaged or missing.
- 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.
