2000 S: Horn Doesn't work when ignition 'On', works when 'Off'?

Horn works when ignition 'Off', doesn't work when ignition 'On'? I have wiring diagram and already confirmed 25A fuse B3 is good, and relay 10 is good. What can I try next (replacing ignition is out of the question to solve a horn problem)?
