Horn not working

I'd check the fuse first. That's the simplest fix if it's blown.

Locate the horn, check for 12 volts applied to the horn when somebody pushes the steering wheel horn switch. If you have 12 volts at the horn then the horn is bad. If you do not have 12 volts at the horn then a fuse, relay, wiring or horn switch is probably the problem.

Engel...did you ever find the problem with these horns?

My 2004 Camry horn stopped working . Then it started working for a month. Now it is not working? Do zu think something g is loose?

Thank U so much.
