I have a 2004 deville with 49k miles. Car is new to me, and there is a high pitch tone which seems to be coming from the instrument panel area. Think ringing in ears sound. It occurs whether car is running or not, key in or out, and the only way imcouldmgetmit to stop is by pulling fuse #7(instrument panel). Any ideas on a cause or fix?

That would be an internal noise from the instrument cluster gauge assembly.Removing and reinstalling the fuse will often temporarily cure the problem.But to repair requires removing the instrument cluster and sending out for repair or exchange.
