City horn want work can anyone help

This is kind of old school, but it is a good place to start. Did you pop the button of the steering wheel? If it is a round disk in the center, you can pop it off and check the contacts. You may have a broken contact, (a small flat piece of metal that would connect when you push the button) You may be able to gently bend that piece so it makes contact. Good luck!

 

Unplug the horn and insert a 12v test light between wire and good ground, then have someone activate the horn while you observe test light, or vice-versa. If the lights illuminates, replace horn, if no illumination then find location of power loss to horn. Sometimes the horn will fail and short, blowing the fuse.

 

99% you have bad horn(corroded inside). it's expensive in the dealer. Go to AutoZone and buy any aftermarket horn for $15. Cut the connector and connect the horn. It will work, I have done on my 2012 Cascadia.

 

Exactly what they said.
