Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box, typically found in the glove compartment or under the dashboard.
Remove the cover and identify the headlight fuse using the diagram.
Inspect the fuse visually or test it with a multimeter. If blown, replace it with a new fuse of the same amperage.

3. Inspect and Replace Bulbs

Remove the headlight assembly as per the service manual instructions.
Twist and remove the bulb holder from the assembly.
Remove the old bulb and replace it with a new bulb, ensuring it is seated properly and does not touch the glass with bare hands.
Reassemble the headlight assembly and reinstall it in the vehicle.

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

5. Check Wiring and Connectors

Inspect all wiring leading to the headlights for any signs of wear, corrosion, or disconnection.
Repair or replace any damaged wiring or connectors.
Ensure all connections are secure and properly insulated.
