A blown fuse might *indirectly* affect the gauge if it's a fuse supplying power to a larger circuit that also includes the gauge's power source (like a power distribution circuit for the instrument panel). To find a potential culprit, you'd need to consult your owner's manual's fuse box diagram. Look for fuses related to the instrument panel, gauges, or the fuel system.
Before replacing any fuses:
* Check the obvious: Make sure the gas gauge needle isn't just stuck. Try gently tapping the instrument cluster.
* Test the fuel sender unit: This is often the source of gas gauge problems. It's a component located inside the fuel tank that sends a signal to the gauge. Testing requires a multimeter and some mechanical aptitude.
If replacing fuses related to the instrument cluster or fuel system doesn't solve the problem, the issue is more likely with the fuel sender unit, the wiring, or the instrument cluster itself, requiring professional diagnosis and repair.
