2006 Infiniti QX56--Steering wheel controls are not working

What is your question?

I am not sure when they quit working as I bought this from a friend just to drive my friends and family around when they came in, so it was merely just a 3rd vehicle that seats seven. But then I decided to turn it into a daily driver and wanted to use the steering wheel controls, for the phone, radio, cruise and horn. Checked all the fuses and then found out it might be the clock spring. Put the new one in the horn worked, but not the controls. Horn quit working a few minuets later. So now maybe a short, took it to a mechanic and they said it was the turn signal switches, bought both the wiper and turn signal switches, that didn't work. Then he said it was the body control module. Well after 2 different modules, that still doesn't work. What in the world do I need to do next? Mind you these wiper and turn signal switches came from a junk yard, along with a different steering wheel to make sure it wasn't the controls on the actual steering wheel. Any other suggestion
