Installation Recommendations
- Disconnect the battery before beginning work to avoid short circuits and ensure personal safety.
- Inspect mating connectors and the lamp housing for corrosion or water ingress; clean contacts or replace connectors if necessary.
- Use a small amount of dielectric grease on the contacts to improve corrosion resistance and electrical reliability.
- Route and secure the wiring so it cannot be pinched by the lamp assembly or trunk panels and is protected from sharp edges and heat sources.
- After installation, verify all lamp functions and error messages on the instrument cluster.
Why This Part Fails
Typical causes of socket failure include contact corrosion from moisture ingress, heat-related deformation from high-power bulbs or poor ventilation, mechanical damage when removing or installing bulbs, and deterioration of insulation and connectors over time. Water leaks into the lamp housing accelerate corrosion and contact loss, so addressing the lamp seal is often necessary to prevent repeat failures.
