1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fog Light Bulbs

Sub-steps:
1. Remove the fog light assembly from the bumper by unscrewing the mounting screws.
2. Disconnect the fog light connector from the back of the bulb.
3. Remove the old bulb by twisting it counterclockwise and replace it with a new bulb of the same type (H11).
4. Reconnect the fog light connector and reassemble the fog light assembly.

3. Check and Replace the Fog Light Fuse

Tools Required: Fuse puller or pliers
Sub-steps:
1. Locate the fuse box under the dashboard or in the engine compartment.
2. Remove the fog light fuse (refer to the owner's manual for the exact location and fuse rating).
3. Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.
4. Reinstall the fuse into the fuse box.

4. Test and Replace the Fog Light Relay

Sub-steps:
1. Locate the fog light relay in the fuse box (refer to the owner's manual).
2. Remove the relay and test it by swapping it with a similar relay in the box.
3. If the fog lights work with the swapped relay, replace the faulty relay with a new one.

5. Inspect and Repair Wiring

Sub-steps:
