Attention: This bulletin DOES NOT apply to vehicles equipped with High Intensity Discharge (HID)
lamps.
This bulletin has been revised to update the Models, Correction sections and Parts/Warranty
Information. Please discard Corporate Bulletin Number 10-08-42-001C.

Condition
Some customers may comment that the low beam headlamp is inoperative.

Correction
Important: DO NOT replace the entire headlamp assembly for this condition.
Replace the bulb and inspect the connector following the procedure below.
1. Remove the headlamp bulb. Refer to Headlamp Bulb Replacement procedure in SI.
2. Inspect the connector.
• If the connector is NOT discolored or damaged, replace the bulb only. For bulb part numbers, see Headlamp
Bulb (Low Beam) in Group 02.727 of the appropriate Parts Catalog.

3991128

• If the connector is discolored at the bulb interface, replace the connector (service pigtail listed below)
and bulb.
3. Cut the wires of the connector approximately 45 mm (1¾ in) from the connector and splice in the service pigtail
connector. Ensure that the splices are not above the connector when re-installing.
EXTERNAL WIRE SPLICES
4. Use Duraseal splice sleeves (salmon, P/N 19300089) for wires spliced external to the lamp. Refer to Splicing
Copper Wire Using Splice Sleeves in SI for splicing procedures.
5. Replace the headlamp bulb. Refer to Headlamp Bulb Replacement in SI.
6. Verify that the headlamp is fully functional.
INTERNAL WIRE SPLICES
7. For wires spliced internal to the lamp, use splice clips (P/N 05297428) and heat shrink (P/N 12355010). Other
splice sleeves and heat shrink tube may not protect the splice from moisture or contain an adhesive that will
cause headlamp gassing.
8. Fold the wire ends in half and overlay the ends of exposed copper wires over each other and crimp the splice
clip over the wires using Special Tool J-38125-8, crimp nest F, to complete the repair.
Note: Inspect the crimp quality.
Caution: Keep the heat shrink above the splice when soldering the splice to ensure that the heat shrink is not
prematurely shrunk and closed down over the wire or the splice area due to the heat from the soldering iron.
9. Solder the crimp and the splice clip.
10. Center the heat shrink tube over the crimp and use the Ultratorch, part numbers 12085116, J-38125-5A, to
shrink and seal the heat shrink tube properly over the splice crimp and the insulated wires.
11. Replace the headlamp bulb. Refer to Headlamp Bulb Replacement procedure in SI.
12. Verify that the headlamp is fully functional.
