Can you tell me why my 2017 Honda Civic's USB port is not functioning properly?

To troubleshoot non-functional steering wheel controls in a 2017 Honda Civic, start by inspecting the wires that power them and the fuse. The fuse is the more accessible option and is likely the culprit, so begin by checking it. To access the fuse box located under the car's hood, first open the hood and secure it in place. Look along the right side of the engine compartment for a black box or case with a visible seam. Opening this case will reveal the fuse inside. The lid of the case should have a diagram indicating which fuse corresponds to which component. If this information is not on the lid, consult the car's owner's manual. Once you identify the required fuse, remove it. A functional fuse will have a thin strip of metal connecting the two visible sections. If this strip is intact, the fuse is good to go back in place; if it's broken, the fuse needs to be replaced. You can purchase a new fuse for around $10, making it a cost-effective solution.
