Humming noise from under the hood?!
Hi guys,
yesterday I realized a humming noise which seems to have it's source under the hood. It's happening intermittently, no matter if the the car is locked or if it's unlocked and the hood is open. Sometimes it is quite regular happening every 10 seconds, sometimes the pause in between seems to be longer. Sometimes it does not happen at all. Does anyone have an idea what this might be? |

Never heard it. Is the car fully turned off when this happens? Regardless, its not normal and shouldn't happen.

No clue what it could be, but that doesn't sound like anything I've ever heard come out of my car.

This is shot in the dark but I believe there might be an electrical short with the horn..
It's easy for it to get water intrusion and begin to fail. If the sound persists, that might be a place to start checking. |

That sounds like coil whine of some kind. Very odd indeed.

Today I did not use the car and there was no noise as well. Also unlocking and locking it did not start the noise. |
