You don't, a bulb is $2. You can replace all 3 while you're in there to LED. Id do it for you if you lived by me.
Just remove the plastic center console piece surrounding the radio and unplug everything. Remove the 4 screws holding the ac knobs to the trim. Then you have to pry open the box. It seems like it isn't supposed to be opened but it will open, I used a small flat head screwdriver. Then the 3 bulbs are in there
