Solution

1. Preparation

Gather tools and parts: Socket set, multimeter, replacement bulbs (if necessary), fuses.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Replace Fog Light Bulbs

Open the hood and locate the fog light assemblies.
Disconnect the fog light wiring harness by pressing the release tab.
Remove the fog light assembly by unscrewing the mounting screws.
Remove the old bulb by turning it counterclockwise and pulling it out.
Insert the new bulb by aligning it and turning it clockwise until secure.
Reinstall the fog light assembly and reconnect the wiring harness.

3. Check and Replace Fog Light Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fog light fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for any signs of damage; replace it with a new fuse of the same amperage if blown.
Reinsert the fuse into its slot securely.

4. Verify Fog Light Relay

Locate the fog light relay in the fuse box (refer to the vehicle manual for exact location).
Remove the relay and check for continuity using a multimeter.
If faulty, replace it with a new relay of the same specifications.
