Buzzing/Humming Noise

When I put the key in the ignition and turn the Jeep on, or turn the key backwards for just the radio I hear this loud buzzing/humming noise. I have no idea as to what it could be.

Has this happened to anyone?

noises? coming from a YJ? that's unheard of.

But if it still runs fine don't worry about. It's probably your heater blower motor turning on and if it's loud than it probably needs to be replaced. no biggie, just make sure you turn all of the heater stuff all the way to the left and the speed selector all the way down

Ok, did this. And it was still there. I looked under the Jeep, all around the engine and fuse box making sure their was nothing missing. Looked at all the dials that are all over my dash board. Carefully inspected my battery. Checked out pretty much everything, then I found the solution.

The Doors. Close them.

It was strange because whenever I had the doors open and wanted to play the radio or start it up, i never heard this buzzing sound.
