I hit my horn on the steering wheel a couple of times. Now my horn doesn't work

Any fuse you checked, did you use a voltage tester on the fuse circuit? Even if the fuse is good, if no voltage on the circuit, the circuit is dead.

Usually the problem is in the steering column/steering wheel. You need to disarm the air-bag, where applicable, before trying to work on it.

Check out the diagrams (Below). Please let us know what happens.
