If the other steering wheel buttons are good then the horn is probably good, but, not a 100% sure thing. Taking the assembly apart to check is not easy and you risk damaging the flex cable. Try putting your hand on the horn relay while tapping the horn button. Make sure the relay clicks or just swap it with the A/C relay. Use the web page I posted earlier to determine which relay is the horn and A/C.
