Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Replace Bulbs

Remove the fog light assembly from the vehicle:
- Unscrew any retaining screws using a socket set.
- Gently pull out the fog light assembly.
Replace the fog light bulb:
- Twist the bulb socket counterclockwise and remove it.
- Replace the old bulb with a new one, ensuring it is the correct type (H11 for XC60).
- Reinstall the bulb socket by twisting it clockwise.

3. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fog light fuse (refer to the fuse diagram on the fuse cover).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it is blown with a fuse of the same amperage.

4. Test Wiring and Connections

Reconnect the battery and use a multimeter:
- Set the multimeter to measure DC voltage.
- Turn on the fog light switch and probe the fog light connector.
- If voltage is present, the wiring is intact; if not, trace back the wiring to locate the fault.
Repair or replace any damaged wiring as necessary.

5. Reassemble and Test

Reinstall the fog light assembly back into the bumper.
Secure with retaining screws and reconnect any electrical connectors.
Reconnect the negative battery terminal.
Test the fog lights by turning them on.
