Hoping someone can help me with this...I've searched everywhere with no luck!

The horn on my 85 Toronado no longer sounds like a tractor trailer instead now it just sounds like a horn...haha. I think one of the horn modules went out. I have no idea where they are located and have been all over the engine bay with my flashlight.

Does anyone know where they are located on these cars? I assume the low note module went out...but not sure how to tell.

Thank you!

 

Usually they are in front of the radiator. I agree that one unit may not be working but don't assume it is bad, you may have a wire pulled loose or a connector that is loaded with corrosion.

 

Cool...thank you. I have to replace the radiator anyhow, so I will look for them then. You could be right because it blew out when I was using the horn...I beeped it 3 times and the last time it sounded like a plugged trumpet! lol Then it sounded different afterwards.

They have replacements at Checker but they are universal...I assume it might not sound the same as the stock one?

 

I found them, thanks to another owner. They are in the fender right behind the bumper. Looks pretty hard to access though...eek.

 

I bet you will find corrosion to be the culprit. Let us know though...

 

If you do need a replacement, I would suggest the salvage yard and look for a bigger Olds. Horns do not usually go bad and the universals at the parts stores will prolly sound different (or even strange), and there are usually no returns on electrical parts. Last thing you need is one that makes that icky foreign 'beep' sound...

I remember the horns being marked H or L depending on tone.
I also remember somewhere that said Olds used two particular notes (like A and F), while other GM cars used others. Can anyone clarify?
