Solution

1. Preparation

Gather tools: multimeter, socket set, replacement bulbs, fuse puller.
Ensure the vehicle is parked on a flat surface and turned off.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Bulbs

Sub-steps:
1. Locate the fog light assembly under the front bumper.
2. Remove the fog light cover (if applicable) using a socket set.
3. Twist the bulb socket counterclockwise to remove it from the fog light assembly.
4. Remove the old bulb and install a new bulb, ensuring it is the correct type (H11 for front fog lights).
5. Reinsert the bulb socket and twist it clockwise to secure it.

3. Check and Replace Fuse

Sub-steps:
1. Locate the fuse box (usually under the dashboard or in the engine compartment).
2. Find the fog light fuse (refer to the owner's manual for exact location).
3. Use a fuse puller to remove the fog light fuse.
4. Inspect the fuse for continuity; replace with a new fuse of the same amperage if necessary.
5. Reinsert the fuse and ensure it is seated properly.

4. Repair Wiring Harness (if applicable)

Sub-steps:
1. Visually inspect the wiring harness connected to the fog lights for damage.
2. If damage is found, use a wire stripper to remove the damaged section.
3. Splice in a new wire of the same gauge and use heat shrink tubing for insulation.
4. Secure all connections with electrical tape or heat shrink tubing.
