The volume buttons and cruise control buttons don't work on my M-sport steering wheel. I have seen other threads that say there horn dosnt work but mine does so im unsure what to do. I've checked fuses and they all seem okay, also no airbag lights show.
Take the airbag off (disconnect the battery prior to that) and check the wiring for buttons - make sure it is plugged in and isn't dried out/worn.
