I see that there is a dedicated horn relay as well. I have a wiring diagram on the way, so I will be able to pull the relay and check out the circuits. |

Shorted? |

Could be. New ones are inexpensive and considering the age, I might just replace all 3 at the same time, regardless of whatever else I find. |
