Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Bulbs

Tools Required: Socket set, Phillips screwdriver, new fog light bulbs
Remove the fog light housing by unscrewing the retaining screws.
Disconnect the wiring harness from the fog light.
Remove the old bulb by twisting it counterclockwise and replace it with a new bulb, ensuring it is seated properly.
Reattach the wiring harness and reassemble the fog light housing.

3. Check and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fog light fuse in the fuse box (refer to the owner's manual for the exact location).
Remove the fuse and inspect it for continuity; replace it with a new fuse of the same amperage if blown.
Reinstall the fuse into the fuse box.

4. Test the Fog Light Switch

Tools Required: Multimeter
Access the fog light switch by removing the panel around it (if necessary).
Use the multimeter to check for voltage output when the switch is activated.
If no voltage is detected, the switch may need to be replaced.

5. Inspect Wiring and Connections

Visually inspect the wiring leading to the fog lights for any signs of fraying or damage.
Clean any corroded connectors with electrical contact cleaner.
Repair or replace damaged wiring as necessary.
