None of the controls on my 2006 Titan crew cab steering wheel work. The horn does not work, however, when I was driving the other day the horn just started blaring. A friend of mine had to actually disconnect it to make it stop because I had no idea where to find the horn relay. I was told to replace the clock spring (?) but I have no idea where it is located or how to change it. Could someone please help point me in the correct direction??
