I did not notice until very recently that the horn does not work. I hear th contacts hitting each other inside the steering wheel when pressed and I an assuming the design is similar to that of an older Mercedes. The wires leading to the horn appear to be connected but no sound. Any insight would be appreciated.

 

Check for power at the Horns.

 

I am learning, how would I go about that? Sorry to ask multiple questions. Thanks tech

 

You can unplug the horns and use a test light to test for power. One end of the test light on ground and the other in the horn wire. Then have someone push the horn button and see if the light lights up.
