underhood relay buzzing. must be bad but what does it do?
Under the hood where the coolant resivour is there are some relays. the outer most relay going towards the passanger side is buzzing. car is drving fine. would buzz when the car is shut off but not when driving. when I went out to the car this am it was no longer buzzing. what is this relay for? I am hoping that its for something I don't need and can just disconnect it.

If its chatter you'll know. Relay chatter happens when the switcing wire has instable/fluctuationg or borderline voltage.
