Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the vehicle is on a flat surface and safely secured.

2. Check and Replace the Fog Light Fuse

Locate the fuse box, usually 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 continuity; replace if blown (typically a 15A fuse).
Reinsert the new fuse into the correct slot.

3. Inspect and Replace Fog Light Bulbs

Access the fog light assembly by removing any necessary covers or panels.
Disconnect the fog light connector.
Twist the bulb socket counterclockwise to remove it.
Replace the old bulb with a new one of the same type (often H11).
Reassemble the fog light assembly and reconnect the electrical connector.

4. Test the Fog Light Switch

Reconnect the vehicle battery.
Use a multimeter to check for voltage at the switch when activated.
If no voltage is present, replace the fog light switch.

5. Inspect Wiring and Relay

Visually inspect the wiring harness for any frays, corrosion, or damage.
If damaged wiring is found, repair or replace the section as needed.
Locate the fog light relay in the fuse box and test it by swapping with a similar relay. If the fog lights work with the swapped relay, replace the faulty relay.
