2. Inspect Headlight Bulbs

Remove the headlight assembly cover by unscrewing the screws with a screwdriver.
Gently twist the bulb socket counterclockwise to remove the bulb.
Inspect the bulb for any signs of burn or damage.
Replace with a new bulb if necessary, ensuring it is securely seated.

3. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Using a fuse puller, carefully remove the headlight fuse (check the owner’s manual for correct fuse location).
Inspect the fuse for continuity. Replace with a new fuse of the same amperage if blown.

4. Test for Power

Reconnect the vehicle battery.
Use a multimeter to test for voltage at the headlight connector while switching the headlights on.
If there is no power, trace the wiring back to the headlight switch or relay for further inspection.

5. Inspect Wiring and Connectors

Visually inspect all wiring leading to the headlights for fraying, corrosion, or disconnection.
Clean or repair any damaged connectors and ensure all connections are secure.

6. Test the Relay

If applicable, locate and remove the headlight relay from the fuse box.
