Ensure the vehicle is parked on a flat surface, and the engine is turned off. Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace Fog Light Bulbs

Remove the fog light assembly from the vehicle:
- Use a socket set to remove screws or clips securing the fog light assembly.
- Carefully pull the assembly out of the housing.
Replace the fog light bulb:
- Twist the bulb socket counterclockwise to remove it from the assembly.
- Replace the old bulb with a new one of the same type (check the owner’s manual for specifications).
- Reinsert the socket and twist it clockwise to secure it.
Reinstall the fog light assembly into the vehicle and secure it with screws or clips.

3. Check and Replace Fog Light Fuse

Locate the fuse box:
- Refer to the owner's manual for the exact location of the fuse box.
Remove the fog light fuse:
- Use a fuse puller or pliers to carefully pull the fog light fuse.
Inspect the fuse:
- Check for a broken filament or discoloration.
- If blown, replace it with a new fuse of the same amperage.
Reinstall the fuse into the fuse box.

4. Test the Fog Light Switch

Access the fog light switch:
- Remove any necessary panels to expose the switch.
Use a multimeter:
- Set the multimeter to the continuity setting.
- Disconnect the switch connector and test for continuity when pressed.
If the switch does not show continuity, replace the switch with a new one.

5. Inspect Wiring and Connectors

Visually inspect the wiring:
- Look for frayed wires, loose connections, or corrosion.

- Use electrical tape or heat-shrink tubing to insulate repaired wires.
- Replace connectors if corroded or damaged.
Reconnect any loose connections and ensure all components are properly secured.
