Ken,
If you have the OE Fiamm horns each trumpet is driven by compressed air from the horn compressor. If one horn works that means you are getting power to the compressor. Swap air line connections on the trumpets and see if it works. Also check the air line to the bad trumpet just in case it has a hole. |

Hi, Ken--one way to test would be to disconnect the wiring from each horn, one at a time, and press the horn button to see if each one honks. |

I have a feeling that only one of my two horns are working. How can I test to see if this is the case? |

Randall,
You should have one wire going to ground from the compressor mounting point to the the compressor, and the power wire comes from the wire loom that runs next to the right side headlamp motor. From that loom there are two wires that split and go to the lower radiator temp sending unit and one that splits and goes to the horn. You should get power at that wire when somebody presses the horn. |

I just ordered the owners manual and supplement, but I was hoping to install a horn before it got here. |

Yes, that is where it is. Cap the wires until you find out. |

Is the compressor on an '82 308gtsi on the passenger side near the radiator? If it is I don't have one installed. What colors are the wires that go into it? I've found several loose wires (never a good sign) and need to figure out which is which. |
