Car Horn Sound Change

My horn did the same here . i have two warranty work now :

1. my driver side vanity lights not working ( the bulb is fine but the wire inside got short or something already covered under warranty .still waiting for the part )

2.horn ( going tomorrow to the dealer )

No one likes a good set of aftermarket horns that are louder and not expensive?

I wouldn't bring my car in to a dealer for a horn....not worth my time and horror stories from dealership monkeys.

That's true.. But I already have problem to fix under warranty ( the vanity lights ). So why not hit two birds with one stone

And believe me I know and lived all the dealer horror . They scratch my door paint to the metal . but they fix it

So yes I always try to avoid going to the dealer
But this one is a must

Don't wanna pay for something that can be fix for free

If you get an aftermarket horn, insure the polarity is correct. If you get the + and - swapped the horn will suck rather than blow. This would be a problem if driving in the rain as it will fill your electrical system with water. You will see the headlights filling....first clue.

Anyway, let me know if I can give more sage advice!

I always wondered why the headlights filled with water. Who knew?

Mine just started doing this today after honking. It sounds wimpy

i got the "mazda 3" horn sound now too.

Is there anything on a mustang that dosnt break?

I went through a deep puddle during a storm and my horn started doing the same thing the OP mentioned. Took it to Ford and they stated it was water related and replaced it.

I had a set of pretty loud horns on my last Mustang

I've noticed when it is cold outside the horn sounds weak. After driving the car for a bit and under hood temps get nice and toasty it sounds normal. Maybe the horn mechanism just doesnt like being frozen ?

I've pondered this too. It makes some sense - there is a membrane inside, isn't there? Like the cellophane in a kazoo? So it stands to reason that it could/would become brittle in -20°C temps?

That said, I doubt that the under-hood temp rise would effect it much...since it's 'waaay over by the outer edge of the G.O.R. and down close to the road. But...maybe.

I just got a Procharger D1x installed and with that install you have relocate the original horn placement to the inner front fener behind the wheel well. Since i got it back i lost half my sound...thinking about upgrading my horns to a different type sounding horn..

For what its worth. The horn is two pieces. A low tone, and another for the high tone. The low tone is closest to the grill and is the one that will catch the most moisture n such. Its very easy to replace, just pull out your airbox. With a 10mm take off one of the horns and youll have easier access to the 8?mm nut that holds the bracket. Reinstall new one. Horn cost me $20

I ordered a new set from ford through work so im paying cost. They are relocated to an easier access point so i will install them myself!

Same problem here, I have just noticed how the horn sound has become much weaker. Will get the car to the dealer.
