I have a 2003 2500 Avy. There was a rattle under the steering column, inside the dash. It was not constant, and it seemed to be more noticeable at high speeds.
After some checking, it appears that the transmission shift interlock (keeps the trans from being shifted out of park unless the brake pedal is pressed, if the ign is on) snaps on to the steering column loosely, and wiggles around.
I stuck a spring underneath it, and the noise has 90% disappeared. Next time I'm at the dealer, I will discuss it with them; for now it's much easier to fix it myself.
The part is located underneath the steering column, behind the knee bolster (see photo).
