Evo 8 horn not working?

Ok so me and my cousin we're out tonight playing poker at a local casino and on our way back to my place we got cut off and when he tried to use the horn we got nothing. We've been trying to figure it out for the past 30 min but we are lost. Checked the fuses but they are new.....
Any ideas?

swap out the steering with another.. see if its the wheels fault or maybe its the horn.

Have you tried checking all the fuses and the wiring?
