Solution

1. Preparation

Gather necessary tools: multimeter, socket set, fuse puller, and replacement bulbs if needed.
Disconnect the negative battery terminal to ensure safety during repair.

2. Inspect Fog Light Bulbs

Remove the fog light assembly from the vehicle:
1. Locate the screws or clips securing the fog light assembly.
2. Remove these fasteners using the socket set.
3. Disconnect the wiring harness from the fog light.
Inspect the bulb:
1. Remove the bulb from the socket.
2. Check for any burn marks or broken filament.
Replace with new bulbs if necessary, ensuring they match the specifications (typically H11).

3. Check and Replace Fuse

Locate the fuse box:
1. Refer to the owner's manual for the exact location of the fuse box (usually under the dashboard or in the engine compartment).
Identify the fog light fuse:
1. Remove the cover and locate the fog light fuse (typically labeled).
2. Use a fuse puller to extract the fuse.
Inspect the fuse:
1. Check if the filament is broken or the fuse appears burnt.
Replace with a fuse of the same amperage rating if blown, ensuring proper installation.

4. Test Relay and Wiring

Locate the fog light relay:
1. Refer to the owner's manual for its location in the fuse box.
Test the relay:
1. Swap it with another relay of the same type in the fuse box to see if the fog lights work.
2. If swapping works, replace the faulty relay with a new one.
Inspect wiring:
1. Check the harness for any frayed wires or loose connections.
2. Repair or replace any damaged wiring as necessary.
