So I tore apart the dash today and swapped out the plain backlight bulbs in the cluster and climate controls for green LEDs. .. Almost a complete success, lol. Not sure what's going on with the fuel gauge. LEDs say you can get them "backwards" so maybe? The housing connection could be messed up too. Since I have to tear half the same shit off to swap in a "new" dimmer switch (Sunday), I'll just pull the cluster again and test that bulb/connection, see if I can't get it working. #DIY
