Electric horn wont stop on Cascadia

I spilled water on my steering wheel, and now my horn won't stop going off. I tried disconnecting it at the steering wheel, but it still kept going off. I then tried pulling the fuse, but to my dismay, that fuse also controls the my cruise control and instrument cluster, so that won't work because I won't be able to know my speed while driving. I'm hoping it dries out by the time I need to hit the road and it will be fine, but if not, I'll need to disconnect the horn some other way if possible. Any suggestions?

 

I don't really know where the actual horn is.

 

I wasn't really able to do that because I was parked near other trucks where drivers were sleeping, plus it was dark. Anyways, I guess it dried while I was sleeping because I put the fuse back in and it's not going off now.

 

You're correct. I was told during an inspection that anything that you have on your truck even if it's not something that you're required to have, has to be in working order.
