The horn on my 90 Civic SI Hatchback is not working. I'm not sure where to begin, or how to get this fixed, but people are always cutting me off in traffic, and I've had people
merge into my lane with no turn signal where at times I REALLY need to have my horn working. Has anyone had to fix a horn in a 4th Gen Hatch? If so, please let me know
what I need to do.. I'm finding random photos when I search on Google, but nothing that really explains the process.

Thanks

 

I believe it shares the same fuse as the brake lights so assuming those still work, look into this:

 

Most likely your problem is the contacts behind the steering wheel. It would also be a good idea to check at the horn (under front bumper). I believe that our horn's are a one wire and the ground is through the mounting point. Make sure the wire is intact and the mount has a good bare metal to bare metal connection

 

Thanks for the replies, I'm going to look into it this weekend!
