Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Replace Fog Light Bulbs

Tools Required: Screwdriver set, gloves.
Open the hood and locate the fog light assembly.
Remove the screws or clips holding the fog light assembly in place.
Carefully pull out the fog light bulb from the socket.
Inspect the bulb for any signs of damage; replace it if necessary with a new bulb of the same type.
Reinstall the fog light assembly and secure it with screws or clips.

3. Check and Replace the Fog Light Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box (usually under the dashboard or in the engine compartment).
Refer to the fuse diagram to find the fog light fuse.
Remove the fuse and inspect it; if the metal strip is broken, replace it with a new fuse of the same amperage.
Reinstall the fuse and close the fuse box.

4. Inspect Wiring and Relay

Tools Required: Multimeter, wire strippers.
Trace the wiring from the fog light assembly back to the relay and the switch, checking for any frays or disconnections.
If damage is found, repair or replace the wiring as necessary.
Test the fog light relay for continuity using a multimeter; replace it if faulty.
