Ok so today when an unruly driver cut me off I tried to lean on the horn unfortunately I got no horn only some clicks, I realize that this means I've most likely got a loose connection to my horn. I however do not know my S4 as well as I would like to as of yet, so my question is simple, where might I find the horn under the hood so I can fix this issue.

A pic would be quite helpful if someone cared to take the time.

Any help would be greatly appreciated

 

the click is your relays in your cpu (drivers side kick panel) most of the time the soldered points are shot ****, so resoldering is always a good idea
