In need of some electrical help. My dashboard turn signal indicators on my 1978 are inop. I have replaced the fuses, bulbs and they still don't work. the switch and exterior turn signals/hazards work as advertised. Not sure what to troubleshoot next.....thoughts?

If you know the light bulbs are good it could be the ground for the tach and speedo it is above the left courtesy light screwed into the hinge pillar. you may need to make sure you have power to the center contact of light socket. those lights are on the same circuit as the front turn lights

If you turn your signals on and the corresponding front parking/signal lights comes on, then the only thing that is left is the dash light, circuit board or the ground for the dash light circuit board. Both sides use the same ground "G101"

Do the indicator lights light up at all, or are they totally dead/dark? A dim bulb would indicate a ground problem, but if neither bulb is lighting up at all, I would have to go directly to the bulb circuit on the dash circuit board.

Been a while since I had time to address the problem. I think it is the circuit. Thanks for all the advice. Now I just need to get motivated to replace it!
