i have an 86 trooper and just recentlythe horn just quit working no warnings i chekd the fuse and its good chekd the conections on the back of the horn and i just cant seem to be able to figure out y its not working please help if you can

 

well i finally figured it out i took the plastic shroud off the steering shaft and found the problem seems that isuzu had the 4 contacts for the horn connect to a conductive circular plate on the back of the steering wheel that is supose to make contact with a small spring loaded conector that comes out of the top of the steering column well my spring was bad and the post had slid in and wasnt touching that plate problem solved!
