I have a basically stock 69. All turn signals and emergency flashers work except the front right blinker and the right dash blinker. Right rear works fine and the blinking rate is correct when signalling. Emergency flasher appears to be blinking faster than it should. I put secondary power to the right front socket and it works fine. I pulled the dash blinker bulb and it lights as well when tested. So sockets and bulbs are working but what is very confusing is the right rear works fine but the dash blinker doesn't light when signalling or in emergency flasher mode. Any advice?

 

And the driving light works fine on the front right as well.

 

Cluster indicators are wired at the firewall connector with front lights.
