The Acura CSX is a compact luxury car produced by Honda for the Canadian market from 2006 to 2011. It shared many of its components with the eighth-generation Honda Civic, including the fuse box and relay. The fuse box, located under the dashboard, houses the fuses for various electrical components, including the headlights, wipers, and audio system. The relay, located in the engine compartment, controls the power flow to these components. It is important to check the fuse box and relay regularly to ensure they are functioning correctly and prevent electrical issues.
