Where is the horn in a 1998 Ford Contour?

The front bumper has an 'air seal' piece that spans the width of the car under the bumper. On each side there is a square access hole just behind the fog light locations. Through this access hole & adjacent the inside of the fender you will find the horn on the driver side. Ford eliminated the passenger side horn after the 1995 model year, but many people re-content it by running an extra wire from the existing horn and installing aftermarket horns.
