Hi, I have a 02 wrx and the guage cluster's backlight started flickering on and off a few months ago. sometimes it would happen every night for a couple days straight and other times it would stop flickering at all for a few days and work fine. Then Last week it completely stopped coming on. Any ideas of what it could be? I checked all the little bulbs behind the cluster and they are all fine. If its a ground does anyone know where it is located?
