Need help please. Husband wants to change it out but can not locate it on my car. Serious people who know what they are talking about. Would like to know if there is a site to see a diagram.
is there a place on the net that we can see a diagram

Follow the upper coolant hose to the engine, before it connects to the engine, it divides the hose to the engine.

l highly doubt u need to replace the whole horn , u need to unplug the horn & clean the contacts with either fine sandpaper or a small wire brush & take the horn off & clean the metal the ground connection , plus any good auto parts store like auto zone can help u find the horn or print u out a diagram for it.

Hope that helps & best of luck.By the way most of the horn failers r related to bad grounds & be sure u check the fuse & almost any horn from a do it yourself auto wreckers can work on that vehicle too.
