I've looked extensively online and nobody has asked about this. There is a sound like an electrical pulsation behind perhaps the glove compartment or the passenger airbag - like an electrical signal to something, in my Silverado truck. It lasts about 3-4 seconds and then goes off, only to come back again in about 30 seconds. Does anyone have any idea what it might be? I don't see any performance issues in the truck.
