: electrical humming noise

11-11-08, 04:32 PM
hi, recent '93 sts northstar purchase, new to the site. Seems the car developed a constant low electrical humming noise, level of noise doesn't change, can't hear it except when idling. Headlites also seem to be pulsating a little, but very rapidly. Anyone else run across this? I would think fuel pump or alternator, but car runs fine, no code errors thanks

Maybe your car is humming because it doesn't know the words.

Is the humming coming from the cabin or under the hood? Can you pin point it a little better?
