URGENT I want to pull this steering wheel off because the horn isn't working, everywhere i look up talks about a screw on the bottom of the horn pad but i can not find it. Please someone help as there are plenty of horrible drivers on the road and i need my horn before i get run off the road by an idiot ps ive tested the horn so i know its working now i just need to work out whats going on with the horn pad
