1. check fuses

2. check all wires running to the horns

3. purchase new horns ( make sure to get one high and one low tone ....)

4. dont know how you'd check the button in the steering wheel.. but check it lol

5. if all of the above fails.. buy a train horn, air tank and compressor and contact Redog about installation instructions

about the high and low tone.. I accidently bought two high tone horns- not even looking at the tone on the package- installed them both.. and the first time I was passin' by someone I knew I gave a honk and it sounded like I ran over a small child.. so make sure you get a high AND a low.
