took steering wheel off......removed the 3 horn buttons on steering wheel and cleaned all contacts related to buttons........cleaned part of steer wheel that comes into contact with column and horn switch.....disconnected wire to horn switch on steering column and cleaned all contact points/connections on both sides........cleaned metal part that depresses on horn switch.....checked horn is working by activating alarm and horn works fine...at least the low tone one is working.......horn is still not working when depressing horn buttons on steering wheel...
