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

asked by on January 08, 2018

I drive a 2010 Ford Fusion SE and about 3 weeks ago my battery died. I had someone replace the battery for me since I did not have time and after fixing the battery the car horn began to stop working. The car horn worked the day after replacing the battery, but since then it has quit working. I checked the fuse panel and everything and the car horn fuse was perfectly fine.

My car has 113000 miles.
My car has an automatic transmission.

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).
