Passenger blinker and brake lights not working

Hi guys, (and gals) I am having a problem with my 65 Barracuda that I need you help with please.

I only have headlights and the drivers front blinker for some reason. No break lights or passenger blinker front or rear.

I have gone over the wires and firewall plug and they look fine.
All fuses are ok.
I can hear the blinker ticking on when turning left, but no ticking noise when turning right.
All the bulbs were replaced one at a time, even thought the old bulbs looked ok. (Just in case)

There is a light green wire that makes a test light blink on and off when the test light is hooked up to the positive terminal and turning left. This same light green wire 4 feet away, where it is hooked to the passenger blinker won't blink at all when turning right.

I hope this makes sense to at least one of you out there and you have some ideas. :-D

Diagnosing wiring problems is the Devil to me! :angry7:
