Mazda CX9 Horn sounds different

[Chelnmike816]

Hi everyone

I just noticed a couple days ago that my horn when I lock my car sounds different almost more high pitched.

Anyone know how to fix or if it's serious?

It is getting to fail soon. I had the same on my previous car. It goes to high sound then dies. You just need to replace the horn itself. 2 bolts and 2 wires
