Interior Lighting (EVAC & Nav Buttons) burned out
 

Hi folks, looking for some help replacing some burned out bulbs that light up the EVIC and Navigation buttons. If you look toward the right of the dash (from driver's seat) you have that area with the 4 directional buttons with enter in the middle (part of navigation I believe), then there are 4 buttons directly to the left of that. These control the EVIC / trip computer functions. There is reset, US/M, step, and ? heck I can't remember what each button is labeled but hoping you guys know which ones I'm talking about.

The only ones that DO work are the right directional arrow, and the two buttons labeled "nav" and "cancel" to the right of the arrows. All buttons on the left side (inc. three directional arrows and enter in the middle) are dark when you have the lights on. All other instrument panel lights work as they should, so assume these are just burned out bulbs. Fairly annoying as I use the trip computer often.

Assume these are just regular incandescent bulbs, anyone know what size. Most importantly, is it a total nightmare getting to them, or is this a not-too-frustrating DIY project? If anyone has any info on how to replace these, it would be greatly appreciated!
