Solution

1. Preparation

Tools Required: Multimeter, socket set, OBD-II scanner, screwdriver set
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent any electrical shorts.

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 pliers.
Inspect the fuse for continuity. If blown, replace it with a new fuse of the same amperage (usually 10A).
Reinstall the fuse and reconnect the battery terminal.

3. Inspect and Replace Fog Light Bulbs

Tools Required: Socket set (specific to fog light housing)
Access the fog light assembly by removing the necessary cover or screws.
Disconnect the wiring harness from the fog light bulb.
Remove the old bulb by turning it counterclockwise.
Install the new bulb by reversing the removal process (ensure it is a compatible type).
Reconnect the wiring harness and secure the assembly.

4. Test the Fog Light Relay

Locate the fog light relay in the fuse box.
Remove the relay and inspect for damage or corrosion.
Use a multimeter to test for continuity.
Replace the relay if it is not functioning properly.
