Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent short circuits.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Remove Fog Light Assembly

Use a socket set to remove the screws holding the fog light assembly in place.
Carefully pull the fog light assembly out from the bumper.
Disconnect the wiring harness from the fog light.

3. Replace Fog Light Bulb (if necessary)

Remove the bulb from the fog light assembly by twisting it counterclockwise.
Install a new fog light bulb, ensuring it is the correct type (typically H11 for this model).
Reinsert the bulb and twist it clockwise to secure it.

4. Check and Replace Fuse (if necessary)

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fog light fuse (refer to the fuse box diagram).
Remove the fuse using a fuse puller or pliers and inspect for continuity.
If blown, replace it with a new fuse of the same amperage.

5. Test Relay and Wiring

Access the relay box, locate the fog light relay, and remove it.
Test the relay with a multimeter to ensure it operates correctly (it should click when energized).
Inspect and clean any corroded connectors in the wiring harness.

6. Reassemble and Test

Reconnect the wiring harness to the fog light assembly.
Insert the fog light assembly back into the bumper and secure it with screws.
Reconnect the negative battery terminal.
Test the fog lights to confirm they are functioning.
