1. pop off your aircon vents (using flat head screwdriver and a cloth)
2. take out ashtray and undo the screw under it
3. pop off your gear surround (using flat head and cloth near handbrake)
4. under four screws (two top, two bottom, to remove the entire center console including climate control panel)
5. take off the four screws (some only have two) holding the climate control panel together.
6. disconnect the two plugs connecting the climate control panel.
7. you'll notice that there are several 'levers' to open climate control panel itself... i use a guitar pick (or three) to open without breaking any levers.
8. you'll find three twist type bulb holders. twist them to remove.
9. insert new bulbs (t10 i think, not sure though). Or make some new led ones up, by pushing the legs through the two little holes in the bulb holder.
10. check to see if they light up. when it's all back together.
reverse process to install again.
Hope that helps.
