i have the pac- rps- gm11, wire harness for the steering wheel controls ect... i had everything hooked up, radio working, and so on, when i would hit the steering wheel control, the volume or any other one, it doesnt work, but the blue box from the wire hardneess LED light would light up as if it was getting the signal from hitting the steering wheel control, but they wont work.... anyone know what i should do or y its doing this, i tried programing it, didnt work, its like its getting the signal but not making it work, could the wire harness be bad?
