Hi All,
I've just bought a 2001 Cooper MPI and the horn has stopped working. I changed the stereo last weekend and I'm wondering if I've 'upset' something behind the dash. The horn was working when I bought it and the alarm still sounds the horn so I know the fuse and horn are good. Research suggests the rotary coupling but I'm wondering if the stereo change has done something.
If it is the rotary coupling, is it recommended to change yourself as the airbag worries me.
