Solution

1. Preparation

Gather tools and parts needed.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or engine compartment).
Remove the cover and identify the fog light fuse using the diagram on the fuse box lid.
Use a fuse puller to remove the fog light fuse and inspect it for continuity.
- Tool Required: Fuse puller.
If the fuse is blown, replace it with a fuse of the same amperage rating.

3. Check Fog Light Bulbs

Access the fog light assemblies by removing the necessary covers or panels.
Remove the fog light bulbs by twisting them counterclockwise and pulling them out.
Inspect the bulbs for any signs of damage or burnout.
- Tool Required: Flathead screwdriver (if clips are present).
Replace any damaged bulbs with new ones, ensuring they are compatible with your XC60.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the fog lights for any signs of wear, fraying, or corrosion.
Clean any corrosion found on connectors with electrical contact cleaner.
Repair or replace damaged wiring as necessary.
- Tool Required: Wire strippers, electrical tape, soldering iron (if repairs are needed).

5. Test the System

Reconnect the battery.
Activate the fog lights and use a multimeter to check for voltage at the fog light connectors.
If voltage is present but the lights do not work, further investigation into the fog light assembly may be necessary.
