Condition

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

Correction

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.

- If the connector is discolored at the bulb interface, replace the connector (service pigtail listed below) and bulb.

Important

Use only Duraseal splice sleeves (salmon, P/N 19168446). Other splice sleeves may not protect the splice from moisture or

provide a good electrical connection. Refer to Splicing Copper Wire Using Splice Sleeves in SI for splicing procedures.

1. Cut the wires of the connector approximately 45 mm (1-3/4 in) from the connector and splice in the service pigtail connector. Ensure

that the splices are not above the connector when re-installing.
