Solution

1. Preparation

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

2. Inspect and Replace Fog Light Bulbs

Remove the fog light assembly by unscrewing the retaining screws.
Disconnect the electrical connector from the back of the fog light.
Remove the old bulb by twisting it counterclockwise and replacing it with a new one.
Reconnect the electrical connector and reassemble the fog light assembly.

3. Check and Replace the Fog Light Fuse

Locate the fuse box in the engine compartment.
Identify the fog light fuse using the diagram on the fuse box cover.
Remove the fuse using pliers and inspect it for continuity.
If blown, replace it with a fuse of the same amperage (usually 10 or 15 amps).

4. Test and Replace the Fog Light Relay

Locate the fog light relay in the fuse box or under the dashboard.
Remove the relay and test it using a multimeter for continuity.
Replace the relay if it does not function properly.
