On my 87 GM, there's a sound and I'm not sure exactly how to describe it but it sounds like a low pitched hum or whine. It sort of sounds like a little electric motor is running when the car is on. I don't think it's coming from the accessory pulleys because it continues for a half a second after the key is turned off and the engine stops.
I checked and it's not the blower fan for the vent/AC. It's not coming from the radio either.
Any ideas on what it might be?
