The lighting for my console display right above the climate controls (time, temp, gas mileage, etc.) is now fixed. Even though it was only the right side that went "dark," I decided to replace all 3 bulbs. Super easy fix that took me all of 7 minutes (only because I had to hold the unit upside down and carefully "play" with the bulbs to get them to drop out).
For those who are interested:
Part# 90010-09017 $3.54 Consists of (2) clear bulbs that are installed behind the mid section and right section of the display panel.
Part# 90010-09018 $3.54 Consists of (1) green bulb that is installed behind the left section of the display panel.
Step 1) Remove pop-out cubby storage unit by simply opening it and then pull at an angle towards your body. Pops right out.
Step 2) Remove Phillips screw now exposed directly under temperature controls.
Step 3) Using two hands, grab a hold of the underside of the temp control unit and pull the bottom section free.
Step 4) Using two hands and many fingers, hold the display portion of the unit and pull straight out.
(I have read that sometimes it will sound like you're breaking clips but it's just them releasing. Mine came out with ease - no "cracking" noises)
Step 5) Release wiring harness clip.
Step 6) Once you have the whole unit released (info panel and temp. controls are all one unit), flip it over to find the (3) bulbs.
With a small flathead screwdriver, you will need to turn the back of the bulbs counter clockwise to release. Flip the unit upside down to wiggle or shake loose the bulbs and they should eventually fall out. Do one at a time.
Step 7) Install new bulbs and put everything back together.
