Did a shop install it for you?? If so, then you may be able to get it under warrenty. Was the siren pointed upward? If it was, then water can collect inside the horn part, and mess it all up. I install DEI stuff at my shop, and I have a bunch of older 514T sirens, all brand new. Let me know if you cant find one locally, i can prob hook you up.
