Constant buzzing sound?

[Max_With_a_Shovel]

It's loudest from the interior of the car and continues even after i shut the car off. What's the deal?

Can you tell where exactly the sound is coming from? It could be something like this:

Could also be electrical, like a stuck relay or something. Try to locate exactly where its coming from

Sounded like it was coming from the rear of the cabin, in the hatch area. Almost like a fan or pump was stuck on permanently. I figured i'd just disconnect/reconnect the battery before i went looking around for the exact source and the noise stopped. For now. lol.

Could be your fuel pump or your ABS unit.

My antenna makes that annoying buzzing sound for like 10 seconds when I turn on and off the car because the teeth on the little motor are broken.
Idk if this helps but it's something to look for?
