Not sure about the 13, but when I looked into changing my console lights on my 08 I found they were all soldered LEDs on the back of the control panel circuit board. I hope yours is still under warranty, if not, take a look at the instructions available either through the service manual (CD) or at one of the kits to change the color of your lighting like I did.
Or, is the light you are talking about at the shifter itself? If so, then just remove the shifter cover and it is probably on a circuit board behind the cover.

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
