2-tone horn now only 1-tone!

[Tony D]

Guys

Before I take my car in to the garage for this has anyone come across it before? What could be the cause, and at worst case how much should I expect to pay to get it back to normal?

If it makes any difference, it sounds like the high tone has stopped working as the low tone is just working on its own.

Thanks.

Check your horns electrical connection...
