I know this is a 4runner forum but I need some help with a 1996 Avalon. None of the buttons light up behind the AC panel so at night it makes it a nightmare for my girlfriend to change the heater or AC. I check the fuse, assuming it's the fuse that corresponds to "panel" in the fuse box, and it looks fine. Do you think all of the bulbs could just be out? I pulled them out and they're so small that it's hard to tell if they are bad or not. Could something else be wrong with the lights? Thanks.
