Dash lights not working? 59 Gmc

[SCHRUMGMC]

I have replaced fuses, Bulbs.. The Gauges lights work..the indicator lights don't work, the right one flashes when I push the Turn signal lever down... Im lost here. There is a Fuse diagram under the dash where things are Grounded, could paint mess up a Ground? Where are the Grounds for this? Bad indicator housing maybe?

Could it be a bad printed circuit?

Gauges all work (I think)

Even the Dome light doesn't work..replaced that Bulb

I know some of you will say, Wiring diagram well I can't read them
