Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect Door Switches

Tools Required: Multimeter, screwdriver
Locate the door switches for each door (typically found in the door frame).
Remove the screws or clips holding the switch in place.
Use a multimeter to test the switch for continuity; it should show continuity when pressed and none when released.
If faulty, replace the door switch with a new one (ensure correct part for the XC60 model year).

3. Check Wiring and Connectors

Inspect the wiring harness leading to the door switches for any signs of wear or damage.
Ensure all connectors are seated properly and free of corrosion.
Repair or replace any damaged wiring, ensuring connections are tight and clean.

4. Reassemble and Reconnect Battery

Reinstall any removed components in reverse order.
Reconnect the negative battery terminal.
Check that the interior lights operate correctly with the doors closed.
