2010 Cadillac Truck Escalade RWD V8-6.0L Hybrid Page 113
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.
