Why might a 2000 Ford Explorer make a loud humming sound when it is cold outside but when you press on the gas pedal the noise stops?

Your IAC (Idle Air Control) valve is going bad. It is attached on your throttle body..

Humming noise on the front passenger side of a 1997 Ford Explorer XLT may be due to a bad tire. Try to jack up the tire and spin it by hand to see if the noise is there.

If a car has a loud humming noise when accelerating, it could be that the air filter is missing. The air filter housing might also be loose. A loud humming noise can also be a signal that there is something wrong with the alternator belt or the fan belt.

Most ceiling fans make a humming noise. If you feel the humming noise is unusual, you should check how attached the fan is to the ceiling, as the vibration of the fan can cause a humming noise.
