Car Horn Not Working On The Right-Hand Side

[Toyota3000]

Hi all

As the thread title states, when pressing the right-hand side of the steering wheel, there's no sound coming whatsoever.

Are there 2 parts to a Yaris car horn ? - the reason I ask is because the left-hand side is working fine.

Thanks in advance.

Ask an assistant to press the horn button at the steering wheel while you check for continuity at the wire running from the relay to the horn button and ground. If there is an open in the wire, fix it and test it again. If you don’t find the open in the wiring, replace the horn button.

The horn is grounded in the steering wheel on a white/red wire. A word of caution, however, to investigate the earth the airbag has to be removed. Not a task for the unwary!
