thanks, ***** ***** colors look like they match the steering wheel heater switch, which wouldn't knock. I'm going to post a diagram of the column below and see if you can tell me the area.

What u thank is the noise

Expert:  K. Wiggins replied 1 year ago.
It's either the electric power steering motor or it's U joints. Usually the U joints on the shaft go out before the motor does. Since you wouldn't be able to hear popping of the EPS motor without a load on it I'd recommend replacing the lower shaft U joints first.
