2010 Cadillac Truck Escalade RWD V8-6.2L Page 108

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.

2. Replace the bulb.

3. Verify that the headlamp is fully functional.
