Horn Fuse keeps blowing

  1. Can anyone help me!!!! /ubbthreads/images/graemlins/noidea.gif

    My horn does not work.
    This happened a year or so ago and I found the fuse had blown so replacing this solved the problem.

    This time, the fuse has blown and replacing it with a new one only blows as soon as you press the horn.

    Any ideas???? /ubbthreads/images/graemlins/shocked.gif
    MOT coming up soon! This is a fail!

    Your help would be much appreciated.

    For info: 2000 A4 2.5 Tdi

    Disconect the horn unit, replace fuse and press again...if fuse blows there would appear to be short in the wiring loom somewhere, if so, a case of tack and trace!

    If it doesn't blow, then the horn unit could be fault.

    May even be bad connections / corrosion in the connecter. Clean all contacts up.
