Can anyone advise how to replace a bulb for the climate control on an 89 Civic? I don't think it's the fuse since the temperature dial and the control 1-2-3-4 on the right still lights up. The indicators below it for feet, head, defrost, etc are the ones that are out. Also, I need to know where I can get a replacement bulb and what size to get. Still would like to keep it white. Advice much appreciated!
