Click on the link.
As you can see, no actual horn relay, but, there is the security module. As far as the security module location, seen two different locations in my database, so I'm not sure of location?
Give me a second, will try to post wiring diagram.

You'll probably have to find it to get the number off it. Do you have your owner's manual? It should show location of the horn relay.
Check the Power Distribution Box under the hood. The cover over it may show relay locations. Look on the underside of the cover.

check for it on google or youtube type " location of horn relay" then your car's model

under the hood ... usually near the battery is a fuse panel. in there you should be able to locate the relay for the horn.. it's likely gone bad. sometimes the relay will be located in the fuse panel inside the passenger compartment

horn relay ....look in owners manual..under hood

is the fuse 26 and the relay is R305

There is the actual horn located in front of the radiator on the support.
I would also check the horn relay. You want to make sure that when depressing the horn button you are getting 12 volts to the horn, but it needs to go to the relay first.
I have a diagram for you :
