2010 nissan versa horn not working

SOURCE: 98 bonneville horn issue- changed both horns,

The HORN Is a GROUND CONTROLLED BUTTON you need to FIRST Check under CENTER STEERING WHEEL Cover to see if it has a Bad Commectiot, After Asuring this there Is c CLOCK Spring UNDER Steering Wheel that is Fairly Common for Failing.

The FOB / Remote Utilizes a Different Part of the Curcuit to Activate Horn, I Hope this Helps you With your Problem as Im Sure of All that I Advised. Remember to RATE ME !!

SOURCE: horn stopped working, fuse and relay is good

With test light check voltage at horn assembly on both wire's, could only have one, horn assembly itself could be ground, have some one press horn button while checking, if there is voltage replace horn assembly, if no voltage horn pad at streeing wheel bad. that's being fuse and replay are good.

SOURCE: Horn doesn't work, where is my relay?

That sounds like the relay is working
Unplug the horn and jump it direct to see if it works.
If the horn works check for voltage at the plug and for a good ground on the other lead.

SOURCE: horn stop working......horn relay clicking

could be the horn, wiring to it or a bad ground, pretty straightforward diagnosis will tell you
