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
1.
Remove the headlamp bulb. Refer to Headlamp Bulb Replacement procedure in SI.
2.
Inspect the connector.
3.
•
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.
•
If the connector is discolored at the bulb interface, replace the connector (service pigtail listed below) and bulb.
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.
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 J38125-8, crimp nest F, to complete the repair.
INTERNAL WIRE SPLICES
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.

*This is a unique Labor Operation for Bulletin use only. It will not be published in the Labor Time Guide.
Note: If only bulbs are replaced, use labor operation 2043350.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
