Why 2012 Volkswagen Jetta Horn Not Working

Blown fuse

The most common cause of a non-working horn is a blown fuse. To check the fuse, first locate the fuse box. In a 2012 Volkswagen Jetta, the fuse box is located under the hood on the driver’s side. Once you have located the fuse box, open it and find the fuse for the horn. The horn fuse is typically a 15-amp fuse.

To check the fuse, use a voltmeter to check for continuity. If the fuse is blown, it will have no continuity. If the fuse is not blown, replace it with a new fuse of the same amperage.

Wiring problem

Another common cause of a non-working horn is a wiring problem. The horn is wired to the fuse box, the horn switch, and the horn itself. If any of these wires are damaged or disconnected, the horn will not work.
