03 Horn Help

I'm looking to replace the horn on my dad's 03 caravan but need a small bit of help. First of all, from what I have read I picked up some indication that there are 2 horns instead of 1. Is there any truth to this? Secondly, I would like help in locating and accessing the horn(s) It has become hard to hear since I drove it through the deep water making it more difficult to locate. Any help would be greatly appreciated.

On 98s they are behind the bumper cover in front of the left front wheel. Yes, there are two.
