Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Repair Wiring

Tools Required: Wire cutter, electrical tape, and multimeter.
Check the headlight switch connector and wiring harness for corrosion or damage.
Repair any damaged wires using splices or connectors and insulate with electrical tape.

3. Replace Blown Fuses

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the headlight fuse using the diagram on the fuse box cover.
Remove the blown fuse and replace it with a new one of the same amperage (usually 15A or 20A).

4. Test and Replace Headlight Bulbs

Tools Required: Screwdriver set and gloves.
Remove the headlight assembly from the vehicle according to the owner's manual.
Inspect the bulbs for damage or burnt filaments; replace any defective bulbs with new ones.
Reinstall the headlight assembly and secure with screws.

5. Replace Headlight Relay

Find the headlight relay in the fuse box (consult the owner's manual for location).
Remove the relay and test it for continuity using a multimeter.
If faulty, replace it with an identical relay.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Turn on the vehicle and check if the headlights function properly.
