How do I repair dash lights on Volvo s80 2003?

To repair dash lights on a 2003 Volvo S80, start by checking the fuse associated with the dashboard lights in the fuse box; replace it if it’s blown. If the fuse is intact, inspect the dimmer switch for proper function, as it may be malfunctioning. If the issue persists, consider removing the instrument cluster to check for damaged bulbs or connections. If you're uncomfortable with these steps, consulting a professional mechanic is recommended.
