1965 Dodge Dart front blinkers and turn signal switch.

Well, this was a morecomplicated matter than I first anticipated. The left parking light, and left turn signal is now working. It was the bulb socket that was a bit corroded and did not give proper grounding. But, the right turn signal, that is a whole different matter. I have taken a wire from the battery to the connector on the inner right fender, and the light is steady on. Moved the wire to the connector through the cowl, on the engine side, and full light. Then moved it inside, still light, and all the way to the connector on the steering column. Got of the GT style stupid steering wheel (had to get a number two puller for that, with 3 bolts), and measured from the red wire that goes in to the switch, and then on the light green wire, that is for the left side, and when the switch is operated the peeper in the multimeter beeps, and when I move the switch to the right hand side turn signal the connection comes to that side. But, when put together, the voltage disappears to the right hand side, but is there on the left hand side turn signals. To the rear turn signals it is fine on both sides. I tried to find a way to open the turn signal switch, but did not have any success with that. So, does that mean I am ordering a brand new for example OER MD2138 ?
