OK, so I've searched the forums, and I've only found one thread with a similar problem, but the solution for that did not work. I have a brand new, verified working relay. The fuse is good. The horn works with 12v from a jumper wire. But, I still cannot get either the key fob or the horn button to set off the horn. Neither will either of those cause the relay to click. I have looked at the horn wire behind the airbag and so far without going through the whole process of disabling the airbag system and pulling the steering wheel apart, the little red wire looks to be intact and in the right place. Before I go through that ordeal, is there anything else that I haven't checked?
