I just replaced my turn signal switch in my 82 not 84 rampage. it works fine but when I replace the steering wheel, the horn honks and won't stop.when I look at the switch, I don't know how it could possibly work. There is a copper ring behind the steering wheel that rides against a copper pin that goes to the horn. The ring is in contact with the steering wheel and goes to ground and causes the horn to honk. I think the ring should not be grounded that world allow the horn to work properly. I must be missing something. I neet a diagram. Bob

behind the airbag is the horn switch i dont reccomend checking the the switch unless you know how to disarm the srs systems but i accidently leaned on it once pushed the plate in and when i pushed on it it went off but if i took my hand off it it would go back on otherwise their could just be a simple short

check all the wiring in the stearing wheel. Cover should screw off from the back side. Make sure the horn is hooked up. Should be in the front bumper. If it still dont work then buy a new one. Should run about fiftenn bucks.

Check the horn actuating contact at the centre of the steering wheel. It may be damaged or mis-aligned.
Also check the carbon contact that runs on the slip ring under the steering wheel (associated with steering wheel horn actuate switch) It may be damaged or mis-aligned.

If none of the above are faulty, you should look for a possible intermittent short to ground on the horn actuation control wiring.

You can remove the horn relay and use a Ohm meter and check the resistance between the horn relay connector terminal No. 86 (Black Wire) and ground. If the ohms are less then 5 ohms replace the horn relay. There are a lot more tests but as Polarcycle states you can do what he suggested other then I believe you have two horns in this vehicle.
