Gauge lights?
To change the gauge lights just take the instrument cluster out by doing what triton said, but be sure to take out the light panel first (I don't know if you do since it sounds like you have power everything, I don't know if all models have the manual light switch) because it doesn't look like something to take out separately but if you just tear it off its an easy thing to break lol. But yea just take out the instrument panel and you'll see a bunch of slots on the back side for bulbs. I did this a couple months ago to replace the check engine bulb, its really easy like a 20 minute job. With the A/C and stuff I would assume its the same way
The a/c light are simple. Pull the vent panel off, it just clips in. Remove the (4) 7mm screws in front. In the back of the a/c panel you will see 2 black twist lock sockets. Those are the bulbs. Post some pics when your done I want to see how it looks!
