Solution

1. Preparation

Gather necessary tools and components.
Disconnect the vehicle battery to ensure safety when working on electrical systems.

2. Check Fog Light Bulbs

Tools Required: Screwdriver set, replacement fog light bulbs (if needed)
Remove the fog light assembly by unscrewing the retaining screws.
Carefully pull out the fog light bulb from the socket.
Replace with a new bulb if the old one is burned out.

Tools Required: Fuse puller or pliers
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 and inspect it. If the metal strip inside is broken, replace it with a new fuse of the same amperage.
Reinstall the fuse and close the fuse box.

4. Check Wiring and Connectors

Tools Required: Multimeter, electrical cleaner, wire brush
Visually inspect the wiring harness and connectors for any signs of wear, fraying, or corrosion.
Use a multimeter to test for continuity in the wires leading to the fog lights.
Clean any corroded connectors with electrical cleaner and a wire brush. Secure any loose connections.

5. Reconnect Battery and Test

Reconnect the vehicle battery.
Turn on the fog light switch to check if the lights illuminate properly.
