take the shifter shroud apart as best as possible and under there youll see a single bulb. should be the same as the bulbs that go in the back of the gauge cluster. they are standard instrument panel bulbs, get them anywhere.
Like everyone else said, theres a single bulb under there. I'd check fuses first. If it's not the fuse, then removing the trim requires a switch between removing phillips-head screws and carefully popping out plastic bezels, but the whole process should take under ten minutes to remove all the trim and get to the bulb.
