Check the fuses related to the low beam lights in the fuse box. A blown fuse could be the cause of the issue. Let us know if this resolves the problem or if you need further assistance.
The fuses are fine, and the battery has power so the engine can start. But my multimeter is on loan, so my own troubleshooting is currently limited.

Try checking the headlight relay, as it could be faulty and preventing the low beams from turning on. You can swap it with a similar relay in the fuse box to see if that resolves the issue. If the problem persists, let us know for further guidance.

All relays are working. All fuses checked, but still no low beam. I can see that the previous owner has added a wire between the headlights.

Inspect the wiring for any signs of damage, corrosion, or poor connections, especially where the additional wire is connected. This could be causing a disruption in the circuit. If you find any issues, repairing or replacing the faulty wiring might solve the problem. Let us know how it goes or if you need more help.

I can add that I have now replaced the light switch, but still no low beam. An authorized Volvo dealer said that the switch cannot be bought new, but he gave me the part number so I could find a used one. In the meantime, I checked the old switch, but found it intact. So now I'll check the wiring.

Ensure that the ground connections for the headlights are secure and free of corrosion. A poor ground can prevent the low beams from functioning properly. If the ground connections are good, continue inspecting the wiring for any hidden issues. Keep us updated on your progress or if you have more questions.
