I am trying to install the 2006 steering wheel audio control buttons that light up on my 2005 GTO. I have the correct 2006 part , I believe, (#92507993), they plug in and all the buttons operate correctly, but they don't light up. Another GTO website has a thread that says you also have to actually remove the steering wheel and replace the 2005 clockspring with a 2006 part. First, I am not sure why since you can easily remove the switches without doing that,and then, what does the clockspring have to do with the buttons lighting up, if anyone knows. Any tips would be appreciated.
