The 2009 Mazda RX-8’s electrical system is protected by fuses. If any lights, accessories, or controls don’t work, inspect the appropriate circuit protector in the fuse panel/block. Inspect the fuse and replace it if it’s blown. Insert a new fuse of the same amperage rating, and make sure it fits tightly.

The following schematic shows the 2009 Mazda RX-8 Engine Compartment Fuse Block and Panel Diagram.
