Post a photo with finger pointing to object humming.
we can not ever guess this.
there are 3000 parts on the car, and ive seen like near each make noise moving fast, 1 time the other.
1: check all fuses
2: makes sure battery voltage is at 12.6vdc rested, key on still close to 12.6vdc , still makes hum.?
my guess is the battery is drained but no proof, im not there use my voltmeter.

Check the fluid level and make sure. If the fluid level is not the problem, I would have someone do a complete check on the front end.

SOURCE: humming sound gets louder the faster i go 05 scion tc

Rather than guess witch one it is( sounds to me to be a wheel bearing or hub bearing) just chg. out both, but if it gets louder when you make a right turn i would say its the left side sense when you make a right turn you are putting more forse and weight on that side.

2008 Mazda Tribute had the ignition switch change.. Engine is not turning over, no sound at all except a small humming sound. What could bethe problem?


Hi, i take it since you changed the ign switch that the car has been turning over if not then you have to check the wiring. The only other humming noise could be the starter motor its spinning but not engaging the fly wheel. Best get them checked.

Humming loud noise


Sometimes depending on what type of tire you have, they can be making the humming sound, other than that you'd have to give more detail as to where you think it's coming from, like the back or the front, the engine or the wheels, transmission?

1978 super beetle won't crank. battery good. turn key, hear faint humming sound, nothing from engine


think you may have a faulty starter motor here ,this year vehicle will be of the pre engaged type so no seperate heavy duty solonoid unlike older cars ,i would expect a click of the solonoid and nothing if the starter has burnt out but its possible that the solonoid on top of the starter has failed but without a look myself and only a description i cannot diagnose correctly .Try some jump leads just to be sure it isnt a flat battery then check the engine earth to chassis cable then remove the starter motor and have it checked out

Hyundai accent 2001 will not start all lights work radio works heater fan works battery in 3 months old when I turn the key all i hear is a humming sound for about 1 min. than nothing. weather has be


The humming would be the fuel pump coming on. It should only hum for a few seconds, then shut off.
Your problem is with the start circuit from the battery to the starter, or from the ignition switch to the starter solenoid. Check the connections at the starter (the big cable) for tightness.
Is the battery charged up enough to turn the engine over? Check by turning headlights on and observe while someone turns key to crank. If they dim a LOT, then either battery is too low, or the starter is bad and needs removing for testing. If brightness doesn't change, then the circuit from ignition switch to starter solenoid is likely not working. Check for 12 volts at the small wire to starter solenoid with key in cranking position. If you have power there, the solenoid may be bad. Remove starter for testing. If no power at solenoid in starting position, then either the ignition switch is bad or the neutral safety switch might be the problem, or the wiring from the switch to the starter solenoid is not passing current.
Good luck.

1994 buick regal 3.8l v6 won't start sometime start


could be a weak fuel pump or mostly plugged fuel filter check at the engines fuel rail for fuel pressure after you start it and it dies...if no pressure or low pressure, start with the filter,its cheaper.the humming is your fuel pump and that is normal.
