I need to get my truck inspected next month but the horn stopped working. Replaced horn with new unit and replaced fuse (wasn't blown but did so for troubleshooting). Neither fixed the issue so assuming horn relay or horn switch. I bought a new relay but don't know where it is on the truck to replace (if you know, please share) or how to remove the center of the steering wheel where horn button is. I tried prying it with decent pressure and it didn't budge so I stopped before I possibly broke something. Do I just pry harder or am I missing something. Thanks in advance!
