Oldsmobile/Buick Repair: fuses, buick skylark, fuses

Question
1985 Buick Skylark Limited - 6 cylinder - Can fuses run down or do they just die suddenly?  Should I replace them all?

Answer
hi connie, blew a fuse huh lol.well typically there is never a need to replace a fuse unless it blows.and if you have only blown one fuse and you replace it with same amp and did not blow again.then prob just a tired fuse.but if it blows more then once then a elec prob.please take a min of your time to rate my help ty connie.....billymac
