Help - Horn does not work

[t1971Chally]

Hey guys,

I have moved on to my next electrical gremlin......the horn! It does not work!!!   I have look at the wiring from the horns back to the firewall and on the inside as well....everything seems to be ok.  I have also checked the horns to ensure they work by touching them with a hot wire from the battery and they both work.  I believe part of my problem is that I am missing the horn relay.  I am just not sure what it looks like and from the reading I have done on the forum it sounds as if it plugs into the top of the fuse panel below the dash.  If this is correct.....then I am missing the horn relay.  I have looked on the forum and performed some searches regarding this subject however each time I get a lead the link or picture is broke or missing.  Does anyone have a picture of what it looks like and where it goes?  Also, where can I get one?

Thanks

Ted

I was in your shoes once. Someone removed my relay. I guess the original might have been bad, but if you go thru the trouble to remove it, why not replace it?   

Yes, it is on your fuse block, but they varied thru the years. It is a rectangular silver thingie.

Hey sorry guys I forgot to mention that it is a 71 Challenger 440.

The relay also functions as the key-in buzzer, that's probably why it was removed.
  It should be easy enough to wire in a common 3-prong relay to serve the purpose

I've had plenty of cars with missing relays and jerry-rigged horn switches. Plug in a new relay and viola!

I guess those buzzers must have REALLY been annoying back then!

Annoying is not the term I'd use  F!@#$%^&* noise

Now that you mention it, mine's in the console until I get the car back on the road.

Hey Bullitt,

You'll never forget & leave your keys in

You can fold-over or cut off one of the tabs and the horn will still work, but no buzzer. I don't recall which tab, sorry.

I think it's the lonesome one, mine is broken off and I always wondered why.  seems like the correct relay is tougher to find locally.

Unfortunately they do not list a horn relay for our models with the fourth terminal, although I suspect the 3-prong relay for the '74 model would work for horn only.

Not to Hijack this too much -- but what about the opposite?    I was driving down the road and all of sudden my horn goes off and it won't quit!     I pulled the horn ring and disconnected the wire inside the steering wheel -- no change.    Ultimately I had to pop the hood and disconnect the horns.     Might it be this relay sticking or something?    This was with my '74 -- no other previous wiring issues and I hadn't touched it!    Any ideas?

could be the relay although I would suspect a ground short in the column 1st
