Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is turned off and parked on a level surface.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the headlight fuse using the fuse diagram located on the cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for a blown filament; replace if necessary with a fuse of the same amperage.

3. Check and Replace Headlight Bulbs

Open the hood to access the headlight assembly.
Rotate the headlight bulb socket counterclockwise to remove it from the assembly.
Carefully pull the bulb out of the socket.
Use a multimeter to test the old bulb for continuity; replace with a new bulb if defective.
Reinsert the new bulb into the socket and secure it by rotating clockwise.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the headlight assembly for fraying or breaks.
Check connectors for corrosion or loose connections. Clean contacts with electrical cleaner and reconnect securely.

5. Test the Headlight Switch

If all components appear functional, test the headlight switch.
Use a multimeter to check for continuity at the switch terminals when the switch is activated. Replace the switch if no continuity is found.
