Do fuses eventually go bad?
Random question, I know, but do fuses just fail after a while? And by a while, I mean like 30 years? :)
Twice in the last six months I've noticed something on the Jeep wasn't working (first time it was the blower motor, today it was reverse lights). Both times it was the fuse. Nothing has changed on those circuits (no additional load, etc.) but I'm also betting they're the original fuses. I've had it since '95 and can't remember ever changing fuses on it for any reason.
So do they just occasionally give up after 30 years of sitting there flowing current or is this pointing at some other problem lurking in the electrical system?
