Hi! Just had a main dealer health check who says one horn is off. Just wondering if it's usually a connection fault at the horn? I had a look under the bumper today and the connectors and horns seem readily accessible?

 

Hey I managed to fix it by checking the fuses and the connection leads.

 

Glad it was an easy fix. Looks like you're chasing several electrical gremlins. Hope they are all this simple to correct.
