Why do the brake lights on my Volvo 240 not work?

If the brake lights on your Volvo 240 are not working, it could be due to a blown fuse, a faulty brake light switch, or burnt-out bulbs. Check the fuse box for any blown fuses that correspond to the brake lights. Inspect the brake light switch, typically located near the brake pedal, to ensure it's functioning properly. Lastly, verify that the bulbs are intact and properly seated in their sockets.
