It's not as easy to change them as previous AVEO's. I took the liberty of trying to figure it out by myself.
So here it is, the 2010 gauges. As simple as can be:
Flip it over, and try replacing the bulbs like you did on typical, previous AVEO's. But it turns out, those three bulbs control the turn signals and the notification box (door ajar, low gas, etc.):
So I looked thoroughly to see where the green light that illuminates the gauges comes from:
And to my dismay, the lights for the gauges are soldered on:
Sad news for a guy who hates that awful green light. I'm going to try finding a piece of film to put in-front of the LED to hopefully portray a different color. Soldering a different LED would be far too difficult and the juice wouldn't be worth the squeeze. I also would probably screw it up somehow.
