Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent any electrical shorts.
Ensure that the vehicle is parked on a flat surface and is turned off.

2. Inspect and Replace Bulbs

Remove the fog light assembly by unscrewing the mounting screws.
Disconnect the electrical connector from the fog light.
Remove the fog light bulb from the assembly by twisting it counterclockwise.
Inspect the bulb for damage and replace it with a new one if necessary.
Reinstall the bulb and reconnect the electrical connector. Reattach the fog light assembly.

3. Check and Replace the Fuse

Locate the fuse box in the engine compartment or cabin.
Remove the fog light fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace it with one of the same amperage if it is blown.
Reinstall the fuse into the fuse box.

4. Test the Relay

Locate the fog light relay in the fuse box.
Remove the relay and inspect for any signs of damage.
If a similar relay is available, swap it to test functionality.
If the fog lights work with the swapped relay, replace the faulty relay with a new one.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the fog lights for any signs of wear, damage, or corrosion.
Clean any corroded connectors using electrical contact cleaner.
Repair or replace damaged wires or connectors as necessary.
