Q: I recently replaced the battery in my vehicle; after replacing the battery the car horn completely stopped working.

To diagnose this you can check for battery voltage at the horn terminals when you activate the horn button. If voltage is present, the horn is defective. If no voltage is present, trace the circuit back to the battery and that will reveal the interruption (use the factory wiring diagram).
