This might be the cooling fan which in today's cars is electric and runs only when needed, not continuously like the 50's and 60's vehicles. When you sit idling, with no cooling air passing over the engine, the coolant temperature rises and causes the fan to switch on. This could also happen during acceleration.
the humming noise is coming from a bad ground on you stereo
A hummingbird
wheelbearing or cv axle enjoy
it could be your tires on the pavement.
id say type and size of tire, and if bearings are bad either or will make that humming sound.
you need a noise filter! go to your local stereo shop and tell em you need a noise filter.
Noises are impossible to correctly diagnoise unless you hear them. TAke it to a good diagnoistition.
I have heard that if you have papers or napkins in the glove compartment box they can get sucked into the air vent which then makes a humming noise that you can hear while driving and as you increase the speed the pitch of the noise gets louder.
no it does not
A humming noise on a 1999 Park Avenue is caused by bad wheel bearings. When bearings are loose or worn they will create a loud humming noise that will get louder and louder as the car accelerates.
its probably your radiator
