Car horns are simple metal diaphragms with coils operating them. They’re usually located right in front of the metal frame tha holds the radiator, right in all the road salt and debri. They’re generally grounded just by virtue of being bolted to the metal radiatro muont, and often the ground corrodes. It’s super easy to check for voltage at the wire and if it’s there a whole new generic horn can be purchased for under $20 at any parts store.
