The horn does not work and we are trying to locate the relay it to replace it on our own if possible.

Do you

Same problem, I know it's the horn 'cuz when I press the button one of the horns blows, but it's too weak to be both of them. Where do I find it? I pulled the two upper engine shrouds but couldn't find it. It must be either in front of the radiator behind the grill or underneath the car.
