How to fix a broken (non-working) horn on your antique car (and adjust the steering wheel)

[@jasonhatfield4747]

This is great! Thanks for filming it and uploading it. I just got a 49 Cadillac and the horn isn't working on it either so this video is helpful to see the basics of how the horns were set up.

Glad it helped.

[@nuffelbagget9173]

The screw is a current adjustment screw. My 1990 Cadillac Deville FSM specifies that the horn should draw between 4.5-5.5 amps. The horn will make a "mooing" sound if too much current is drawn and a "groaning" sound if too low. I am not sure if this applies to all vehicles but it should help you get in the ballpark.

Thank you for this video .I would like to point out that the wire that runs thru the steering column provides a path to ground to trigger the horn relay . The power at the relay ( positive ) is constant .

[@billpayne3983]

Excellent explanation. Especially on the horn relay. Same as on my ‘53 Hudson. Thanks.

[@innov8tive1]

You state that there is power coming up to the horn switch. This is not really the case. The power goes to one side of the relay coil, the horn switch provides the ground in order to activate the relay and make the horn work. You can measure voltage at the horn contact when the horn is not in use but what you are seeing is the voltage that has passed through the coil of the relay.

[@RaybuckAutoBodyParts]

You're right. I misspoke. Some 4 prong relays could require power through the horn switch, but in this 3 prong setup the horn is completing the circuit.

@@RaybuckAutoBodyParts Just wanted to clarify that so someone wouldn't attempt to run 12V pos. thru the horn switch and create a whole new issue. I help many classic car guys with electrical gremlins and I've seen many attempts at repairing them in interesting (albeit incorrect) ways. Keep up the videos, things like this are what make KZbin such a wonderful resource!

Thank you. I have a 53 and this helped me troubleshoot my horn not working

[@123jones8]

Thanks for the video, well done! I'm working on a 50 chev PU. Hopefully I can get the horn working.

Information on point! Good job buddy

[@daleswirsding4714]

VERY HELPFUL! Thanks

[@georgephilpot-bk3tn]

I have a 1956 buick and the horn was working before I changed the old steering wheel to another steering wheel. After I installed the new steering wheel the horn stopped working. Please help me.

[@danielcloutier1861]

The adjustment nob on the back. Is intensity switch??

[@GenerationOldschool]

Very well explained video!! I hope other how to KZbin videos where like this one

[@RaybuckAutoBodyParts]

Thanks. Let us know if there are any other how-tos that you would be interested in seeing.

Raybuck Auto Body Parts I tried doing what you did and my horn didn’t work

[@RaybuckAutoBodyParts]

@@GenerationOldschool Are you getting power to the horn ring? How about before and after the relay?

[@GenerationOldschool]

Raybuck Auto Body Parts nope, I press the horn and nothing happens. It used to work 3 days ago. I checked the connections by the horns in front of the grill and they are done

[@RaybuckAutoBodyParts]

@@GenerationOldschool If you have power to the horn itself, then the horn may have gone bad. If there's no power anywhere then you may have just blown a fuse. If it was working a few days ago, then I'm guessing it's either a fuse, the relay or the horn itself.

[@scottschmittmusic]

I just got a 52 Styline and noticed both wires were cut for both horns?

[@cocopublicnews6766]

My horn just started going off and won't stop I checked the button that's better than expected would a corroded relay cause that? It's a 49 pontiac

[@RaybuckAutoBodyParts]

Typically that's caused by the horn ring constantly making contact, which can be caused by a worn out spring. There's a chance that the relay went bad, but usually the relay would remain open and the horn just wouldn't sound.

[@lisad476]

Ty sir!!

[@RhubarbCat-lb9bm]

Nice going over everything but the horn it's self.
