INTERIOR LAMP

WARNING: EYE PROTECTION SHOULD BE USED WHEN SERVICING GLASS COMPONENTS. PERSONAL INJURY CAN RESULT.

CAUTION: Do not use bulbs other than those indicated in the Bulb Application table. Damage to lamp and/or Illumination Control Module can result. Do not use fuses, circuit breakers or relays having greater amperage value than indicated on the fuse panel or in the Owner's Manual.

If a vehicle experiences problems with the interior lighting system, verify the following are in operational condition:
- Battery connections
- Charging system
- Interior lamp bulbs
- Illumination Control Module/Headlamp switch
- Wiring harness connectors

For complete interior lamp system schematics and diagrams, see interior lamps/lighting schematics and diagrams.

Each vehicle is equipped with various lamp assemblies. A good ground is necessary for proper lighting operation. Grounding is provided by the lamp socket when it comes in contact with the metal body, or through a separate ground wire.

When diagnosing the interior lighting circuits, remember that high generator output can burn out bulbs rapidly and repeatedly; and that dim or flickering bulbs can be caused by low generator output or poor battery condition.

When changing lamp bulbs, check the socket for loose pin connections and/or evidence of corrosion. Repair as necessary.

When it is necessary to remove a component to service another, it should not be necessary to apply excessive force to bend a component to remove it. Before damaging a trim component, verify hidden fasteners or captured edges are not holding the component in place.
