Audio Steering Wheel Controls Not Working On Nissan Cube 2012?

Need help trying to resolve why my 2012 Nissan Cube Steering wheel controls do not work. Little bit of background when I first got the car it worked fine until I notice slowly it started not working when pressing the audio control buttons. Finally one day it completely stopped though this was shortly after my horn went out and I replaced with a aftermarket one. It worked for maybe 5 months after the horn was installed. Though suddenly it completely stopped working no matter what I did to get it to work again. I already got a new OEM spiral/clock spring cable installed recently, replaced the radio with a pioneer radio and installed the steering wheel controls though did no work . Lastly I replaced it with a brand-new steering wheel although nothing seems to be working. I know it worked when I first got my car although now its seems nothing I do can actually fix the issue. I really appreciate any assistant and thank you!
