Thanks for the response. Looks like the whole assembly is $70 an maybe just take a chance and just replace the whole thing. The horn isnt that important to me, except to communicate with my dog.

My horn continued to go off even after hitting the button, so I turned off the 500. The horn does not work now? I pulled out all the fuses and relays, and they all look good? I have limited mechanical abilities and no multimeter. Any quick fixes out there?

Thanks, D
