Does anyone have any idea why the pitch of the horn on my 2004 Deville has changed? it used to have this beautiful deep, loud pitch and now it is much higher pitched. Can this be easily fixed?

There are 2 horns - different pitches combine for the "Cadillac honk". Either one is dead, there's a wiring problem, or one of the electric diaphragms is cracked.
