- In this video i will show you how to dissassemble, clean, repair and reassemble an A.C. Delco horn found on 70s 80s and 90s cadillacs and other GM vehicles. NOT TROUBLESHOOT YOUR HORN PROBLEM! Once you have established your problem to a mechanical malfunction within the horn, (Not an electrical problem within the car) then this video should help you.

Great job, mostly everyone on the web just tells you to replace without really helping to fix them. Thanks a lot.
Lol it actually did help me troubleshoot my horns because I'm an IDIOT. I have those same horns or very similar in the A and F notes in this '89 Firebird which I acquired last summer, and they never sounded off. I always assumed that the horns were busted but I just didn't know how to test them properly because I had no idea how those one-wire horns work as far as power wire and ground go so thank you for showing how that works! I feel like an idiot for not figuring out by myself that they were grounded THROUGH the mounting bracket onto the car. In retrospect I cant believe it wasn't more obvious. I finally tested them correctly and determined that the horns themselves are just fine so I'm hoping it's the relay. I only just figured out how to expose it from looking online so the next step is of course to do that and then hit the horn button to see if the relay clicks or not. Fortunately the relay for the horn is right underneath the steering column so I shouldn't have a problem doing that and I guess I'll go from there. The horns are a bit rusty with paint bubbling and peeling off so I'm probably going to use your technique just to clean them up a bit so they don't rot any further and then I don't have to spend a bunch of money on new Delco horns. Thanks again!
Poor cameraman is dying near the end lol
Thanks for the video. Good job of explaining everything so clearly. Keep up the good work.
I'm about to take the stock horn out of my 2017 Civic Hatchback and install a Cadillac 4-note system. I went to two junkyards and pulled three sets of horns (eight horns from two '95 Devilles and four horns from a '96 Deville). I'll test them out soon. I'm sure I can put together one whole working set out of the twelve. Some look like they're top notch for being 20+ years old, but some definitely have got weather-worn over the decades.
Thank you for this video. I'm confident enough to pull them apart and fix them if I have to, now.
The gut who was filming was choking lol at the black paint spray lol
Nope
Epic repair video and an epic handle-bar mustache' to boot! Thanks for the info!
Recently pulled my horns of a 79' vette because they didn't work. I haven't bought replacements yet because I really wanted to try to save them. I will give this a try. Thanks for the share.
Great video and troubleshooting of your horns. Tho I didn't have the benefit of this video years ago while I was rebuilding the horn on my Norton commando which included rewindind the coil as well you covered all of the problems that I encountered . Thank you for sharing your horn repair experience with us all!
Thanks for posting. This helped a lot. My horns work again!
Awesome presentation ,thankyou .
Nice job!
Your work is good!
Great video!
Thanks again.
Ultimately a cameramen who does a excelent job, very smooth filming.
And you spray Jason to death. Although breathing difficulties he's filming.
Or where he was after you sprayed horn, Jason and the floor?
Anyway, great job from both of you.
Great video,iam gonna do exactly the same for my 68 impala, only 1 of the 2 horns are working and now i can fix em. Thank you soo much, very imformative video.
Very helpful. Thanks!
Thanks for the video,you just saved me a lot of trouble and money
Great video! Very informative. Thanks.
the beauty of old cars....they are simplistic genius...I love the way America created things that the everyday person could afford to maintain....when making 20,000 to 30,000 a year wouldn't hurt you
Great video. I put 4 note horns on all my cars. On about 1/3 of the horns I have repaired, the connector was either rusted, and/or the magnet wire needed to be re-soldered. You need to scrape the lacquer insulation off the end of the magnet wire in order to get the solder to stick. It is pretty easy to get the solder to stick to the actual terminal post side. I always polish the two contacts with 600 Grit sandpaper.
You can test the horn that you repair the wire on by screwing it all together without Permatex and applying 12v to it. It will sound lousy, but it is just a test to see if you get continuity and oscillation of the diaphragm.
Also, make sure you mark where the two halves line up. It is possible to glue the whole thing together with the mounting bracket in the wrong place.
I always paint the inside bare metal with POR-15 because water gets in there and rusts it out from the inside.
Then I put on the permatex and screws and screw it together, and paint it. I almost always have to turn the adjusting screw out in order to make it as loud as I want it. I make them as loud as I can get them!
FYI. . . you cannot buy 4 note horns anywhere, and you can only find them in Junkyards if you are lucky. They were mainly in Cadillacs but were also in Roadmasters, and the big Buicks and Oldsmobiles too. I don't think they were in any Chevys.
Nice training video helped me. A +
Great video! I have a 1985 Dodge D100 that one of the two horns doesn't work and I believe that they're pretty much the same as yours, single terminal body grounded... Off to work I go! Thank you!
It was really nice of u sir showing us how to do it if i had a garage or work shop i would try to do it sometimes "Thank you "
good video. how much would a new or used horn cost instead of repairing the broken one?
Very nice job......Thank You........
Good job! Very smart.
Thanks for the video!
good video!! thank you!!!
ive always wanted to know if you can fix these fuckers. i have 12 gm cars and now all the horns will work THANK YOU ,,,,saved me some money
beep beep new automobile watch tobacco road
your workshop is nice ! lol from Bangladesh
Good job!
Awesome video and great job! How many of you viewers got a cute chuckle at the end when you noticed that it was a classic HEARSE? Hehe! : )
great job
Great stuff dude!
Thank you. I have 4 horns on my 97 D'elegance. If they are not rotted I will try this.
Thank you for this great video. I watched this like 4x and finally got to work today. I had two Delco horns not working, both the very rare C and D note.
On the C note *I* made a major F*, I dremeled a bit too harsh and ruined the coil. Half of it around the Dremel bit :(
So for those doing the same referbishment: be carefull not to dremel too much to the side, because that is where the coil is.
So that one is on me, ruined.
The D note was very rusty and its diaframe was 1/3 rusted, holes. Gone. Rest seems OK and rust inside removed.
Hence a question: do you now know what causes the actual note?
Is it the moving diaframe itself, the body where the coil resides, or is it the shell shaped amplifyer? What makes the difference in tone?
Obviously, I now do have parts to create 1 working horn from this mess of two broken ones.
I'll give it a try. Still I need either an extra C or D note to get the complete 4-set. Until now, I had 2 Delco horns on two vehicles.
Great job bro
Awesome video! I had to buy one because my wife needed one....with all these crazy drivers after work and pickin' up kids, yadda, but I think I might fix the broken one and put it on my tractor.
thank you bro .. youhelp me to much with this video
Great video!! I got a box of them I can fix now!!
Thanks Bro, I am planning to find a 4 note set of GM horns. Now I know success is certain, Even if they do not work well or at all to began with,
Tabby1957Cat I have seen horns that have a screw that tunes the horn, so you could tune each horn to what pitch you like....
Nice work. I would also rather repair than replace myself, as you did. Now to make my S15 sound like a caddy........
..thanks so much!,...a little dark, but I watched a couple times.
thank you mate.
This video is under-watched/liked.
Gonna save me $ LIKED!
THINKING: you should ooze it with corrosion/weather protection liquid, re-meltable/re-usable.
Gerald, I have a horn that the contact point broke off...can it be replaced if the take down occurs as your video has shown?
No, the contact is rivited into the plastic which is pressed into the horn casing. If you have any contact left sticking out of the plastic, i suggest soldering a wire to it and crimping a male connector to it.
Gerald Carroll the horns I have are from a buick Roadmaster. The one that is broken is the D note from the passenger side. It has a # on it as follows: 16574. Is there any difference in that and a universal D note I can get from the local parts store in terms of decibles...This is for a Ranger project truck I'm working on and I particularly like to tone of the 4 note horn!
Great video. I am fixing my C note and it works until I install the parts that need to be bolted down. At that point, no spark on the battery. I feel like the diaphragm loses it's flex.
that screw i believe is to adjust the horn tone
The screw on top of the horn adds or relieves pressure on the inside contacts of the positive current
By dailing out that screw out counter clockwise one half turn the horn becomes louder , I'm not sure why they have it adjusted to make it softer maybe due to power draw or noise ordinances, IE NYC wear people use their horn a lot. But when running that wonderful ACDF notes delco remy quad horn setup louder is what your after.That may or may not cause that plastic to get down inside the electromagnets but I'll find out.seems the ones needing repair are factory set with a softer tone and not used much
So maybe more use and the electromagnet going further into the hole with use may actually keep them working longer. Anyhow they are louder.
Datsun made some almost exact replicas of the delco ones caled miyamotohorn. And turning the screw atop the horn a half circle counter clockwisenthey get twice as loud.then get a pair of those fiamm cheap new car horns for higher notes to mix with thebdatsun lower notes 70s horns and you get a quad set up and have a china&Japan train horn in the econo bubble cars... The delcos are getting harder to find and getting spendy too.great to know they can be repaired...
Thank you sharing! Great knowledge ,no need to buy things you don't need ! We have become a throw away society.
Not only that, the C# and D# horns are hard to find. No one makes new ones that replace them, and E# + F# sounds wrong on a big old car.
Hahha at the beginning he said GO.
am i saying right?i ask that because im from serbia
my horn blows when I turn on my lights on my 2001 cad. northstar do know what that may be from
Possibly bad turn signal stalk assembly
Dude can you sent me a website where you can get that mini circuit test jumper to literally test continuity with sound of a horn with a rechargeable car battery plugged into🔌🔋a car battery wall charger
On google plus

gaskget?
i use pliers for edges
As good as it gets.
Those are "Delco Remy" Horns, Not "AC Delco".
Yes i know, But they're all built the same... I labled it "A.C. Delco" because they're the most populer. Good Eye though.
If you hit the copper coil with the grinder your done, junk.
i use pliers
Nice vid, but I’ll just spend $25 on a new horn. My time is worth more than the time to go buy screws, buy a gasket, grind shit.
It’s a throw away part.
I’d hold on to them, they won’t be around forever, especially a 4-note caddy horn.
the paint is hazardous, it is a bad idea to do it in basement without ventilation. Humans lungs are not strong enough to withstand chemical abuse. You and the camera person should go get yourself check with your doctor. Anticipate future breathing problems
Well thank you doctor! Being that i don't really give a fu@k about the minimal amount of exposure to the fumes and that it was so long ago.... I respectfully decline your advice to visit a doctor. But feel free to paint your horns in a well ventilated area if you like..... our not, i don't care....
Gerald Carroll that is your choice and right but no need to curse? why curse. You are on a WWW, sharing with everyone, and I don't see any thing out of disrespect to make an observation on your video.
arshi khur if you don't like the way i talk then that's your problem.... i wasn't "cursing" at you. Just putting a lot of emphasis on how much i don't care about your advice... understand?
Gerald Carroll I did like your video and its very helpful, thank you for teaching
Good stuff but the hardware costs more than a new horn nowadays
Yes but the garbage replacement junk is inferior to the original sound these classic horns produce... And when restoring a classic vehicle, the more ORIGINAL parts you can rebuild the better. You want hear a HONK HONK from a Cadillac, Not an eep eep....
