Evening all,
Just been out to try to diagnose my lack of horn. I do not have 12v at the horn on the purple/black wire (when the button is pressed). I have removed the steering column cover, and removed the multi plug from the rear of the rotary coupler - I have got 12v at this point (purple/black) and I have got an earth on the black wire. when plugged into the coupler, and the horn pressed, no voltage leaves the plug. Do I need a new coupler? The SRS airbag light is functioning correctly. Is there any "contact points" I can clean when the coupler is removed?
With the multi plug removed, and I earth the purple/black wire, the horn sounds. So all wiring from inside to the horn is ok, plus the horn relay itself is ok.
Also, what kind of bolt / screw holds the airbag?
Ryan.
