Due to the way fuses are engineered, the likelihood that a fuse would become faulty without blowing is pretty slim, but there are rare instances in which a fuse might appear completely fine, even though no current runs through it. Inspect the wiring for loose connectors, unsupported wires, wires rubbing against sharp corners or edges, wire grommets that are missing, etc. .
