Mazda 6 horns not working when using steering wheel
 

Hello to all ; On my Mazda 6 2007 the horn stops working (when using horn switch from steering wheel ) When i lock the doors with key fob remote control, the horns comes on briefly as suppose to be , to indicate doors locking; So i think everything related under the hood (relay, fuse , wiring and horns ) are ok ; I did double check anyway and yes ,all are fine; So i suspect either clock spring or-and BCM module... But from my steering wheel every others controls (cruise , audio , radio, mute, etc ) are operational from steering wheel; About the BCM module : i do not have the complete electric schematics so i would like to know if the BCM module is involved in the circuit for horns when using the key-fob remote for locking the doors ?? Because i do not know what to look (or change ) at first : BCM module or clock spring ? Many Thanks
