Horn on my 2014 Toyota Corrola LE is not working

yes it is probably a fuse issue. could also be a connection issue in the steering wheel or under the hood,

I have same issue, was told to disconnect negative from battery , pump brake 10 times, connect back, start car, tried it and reacts better to functions but screen still blank, will try again though, good luck to you, Anthony,

Mine was chewed through wiring. Horn is in front of radiator...wiring was hanging below it, plug still in connector at horn. Horn is a small (3 inch or so diameter, half inch thick) disk near top of radiator.

It took 8 months for an answer?

I know this is late, but have you checked the connector at the horn? Pull the wire; if it comes off the connector, that's your problem. Apparently, this is a common thing with this particular model.

after the recall of my vehicle toyota corolla S 2014, the horn doesn't work. That can be the reason?
