Blinkers inop,car hums,atlenator in question

fuses
alternators

#1
  1. Blinkers blew a fuse, replaced twice, replaced again w/ 30gauge fuse. Saw little smoke, removed fuse- now it doesn’t work at all



    2. Car engine hums (sounds likes a horn) terribly when at idle or parked. Checked out service engine soon code- it states fuel to lean or rich, problem w/ #2 firing



    3. Autozone says alternator is bad, Firestone say it’s good (they replace it less than a year ago) I may have electrical problems which is causing a drain on my battery. I don’t know if I’m running on pure bateery power or not. Car works fine if I don’t turn on radio or AC



    -All are separate problems on a 2001 Nissan Maxima

  2. Hums comes from engine idler puller/y, belts= alternator. $624.48
