Horn isnt working...

i've got an '03 Cavalier and my horn doesnt work, I've already checked the fuse in the fuse box and its still good. When I push on the horn nothing happens.... any suggestions.

it may be your relay switch. my horn doesnt work either but i just said screw it since im not driving it right now.

is there a way I can find out for sure if thats what it is without having to take it to a mechanic??
