My alarm module seems to have crapped out a couple days ago. It randomly goes off and honks the horn, but not in a steady pattern like normal - instead, it randomly honks like a madman is wailing away on the horn. When I unplug the alarm module, all is fine. I'm thinking the alarm module is shot, but I can't seem to find a replacement one. Does anyone know a part number, or possibly other mazda models I can use one of these from? I'd rather not have to wire in an aftermarket alarm if I can avoid it.
