Horn not working :(

[Guest]

When I press the horn button, I hear a quiet pinging noise in the right horn, and when I put my hand on it I can feel the ping and the vibrate a bit. But no horn noise...what to to do first? One day it worked, the next day it didn't

First thing to try is cleaning the connections and check that you are getting about 12V with the motor stopped. After that the internal contacts wear out and can be adjusted by turning the screw on the horn. After that your looking at the horn switch. The ball bearings corrode. The size that worked for me was 3mm.

And where might these contact adjustment screws be?

Usually dead center on the back, sometimes with a locknut.
I'll see if I have one lying around and get photo

First post in this thread has the general idea. Don't read to much into the advice about colour variation
