Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, turn off the ignition, and disconnect the battery to prevent electrical shock.

2. Inspect and Replace Headlight Bulbs

Remove the headlight assembly by loosening the retaining screws or clips.
Disconnect the wiring harness from the bulb.
Remove the bulb by turning it counterclockwise and replacing it with a new bulb of the same type.
Reconnect the wiring harness and reinstall the headlight assembly.

3. Check and Replace Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the cover and check the headlight fuse; it will be marked in the diagram on the cover.
Replace any blown fuses with new ones of the same amperage rating.

4. Test and Replace the Headlight Relay

Locate the headlight relay in the fuse box.
Remove the relay and test it with a multimeter for continuity.
If faulty, replace the relay with a new one.

5. Inspect Wiring and Connectors

Visually inspect wiring harnesses and connectors for damage or corrosion.
Clean any corroded connectors with electrical contact cleaner.
Repair or replace damaged wiring as needed.
