97' grand caravan horn trouble

I attend school a Tech HS in the automotive area and as a project decided to bring my mothers 1997 Dodge Grand Caravan 3.3 Liter in. I was going to work on the horn but can't find any diagrams and even my instructor is unsure about where it would/could be located in the compressed front end. So...if anyone could help me in any way it would be greatly apprectiated.
