Hey. I am new to this forum. Sorry if I'm not posting in the right place. The horn on my 2008 ford focus ses sounds like it is dying. I have located it and I know how to take it off. I was just wondering if I can use a horn from a different vehicle to replace it. My parents have a dead saturn car and chevy van. Could I use a horn from one of those vehicles to replace mine? Or are they not interchangeable?
