1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Replace Blown Fuses

Locate the fuse box: Refer to the owner’s manual for the exact location.
Remove the fuse: Use a fuse puller or needle-nose pliers to extract the fog light fuse.
Inspect the fuse: Check if the fuse is blown (the metal strip inside should be intact).
Replace the fuse: If blown, replace it with a new fuse of the same amperage.

3. Replace Fog Light Bulbs

Access the fog lights: Depending on the design, you may need to remove the fog light cover or bumper.
Remove the bulb: Twist the bulb socket counterclockwise and pull it out.
Install new bulb: Insert the new bulb into the socket and twist it clockwise to secure it.

4. Repair Wiring Issues

Inspect wiring: Look for any damaged wires or loose connections leading to the fog lights.
Repair or replace: If damaged, cut out the affected section and splice in new wiring, using solder or wire connectors.
Use electrical tape: Wrap any exposed wiring to prevent short circuits.

5. Test Fog Lights

Reconnect the battery: Reconnect the negative terminal and ensure all connections are secure.
Turn on the fog lights: Activate the fog light switch to check if they illuminate.
