Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and replacement bulbs (if necessary).
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to ensure safety during electrical work.

2. Inspect and Replace Fog Light Bulbs

Locate the fog light assembly beneath the front bumper.
Remove the fog light assembly by unscrewing the retaining screws using a socket set.
Carefully disconnect the electrical connector from the bulb socket.
Remove the old bulb by twisting it counterclockwise and replace it with a new bulb (ensure it matches OEM specifications).
Reconnect the electrical connector and reinstall the fog light assembly.

3. Check and Replace Fog Light Fuse

Locate the fuse box, typically found under the dashboard or in the engine bay.
Identify the fog light fuse using the diagram on the fuse box cover.
Pull the fuse using a fuse puller or pliers and inspect it for continuity.
Replace the fuse if it is blown with one of the same amperage rating.
Reinstall the fuse and close the fuse box.

4. Verify Wiring and Connections

Visually inspect the wiring harness leading to the fog lights for any signs of wear or damage.
Use a multimeter to test for voltage at the fog light connector with the fog light switch activated.
Repair any damaged wiring or connections as necessary.
