So getting the horn working is one of the last nonfunctional pieces left to fix. Pulled the steering wheel, cleaned the contacts, used the dielectric grease, replaced the pin and spring but still no horn. Checked the fuse which I’d already replaced. Going to try replacing the relay. The part comes back as a horn relay as well as the taillight relay. When I removed it the taillights stopped working so I don’t know if it’s the relay for both the horn and taillights or not. If the taillights work with the relay Id assume the horn would as well. This relay was just above the fuse panel in the drivers kick panel.
