Front turn signals not working

I just wanted to say thank you to Crewchief, 67Dart, and Redfish. After a month of torture, nearly everything works, and your suggestions helped me figure things out.

I replaced both of the flasher units, just to be safe. I also ended up replacing the rear wiring harness, as it was giving me sporadic lighting in the back, and there was no point fighting with it.

The hazard switch itself was not putting out power to the other prongs when in the on position, so I ended up taking the hazard switch apart, cleaning up the contacts, and reinstalling. That solved some of the power to the front parking lights issue, and I had power to all the prongs when on.

For the front parking lights, it turned out that the spring-loaded bulb contacts in one of the lights had somehow rotated and gotten jammed inside the housing. It was jammed in a position where that light bulb wasn't making clean contact; once I forced it back into position (there is a guide tab in that housing), the light worked fine.

The turn signal switch was the real culprit here, though. The contact wire on the replacement cam was slightly too long and was hitting the plastic instead of the contact point for the right rear signal. I trimmed that, and the signal worked, but the brake light did not. Took the column apart yet again and bent those contact wires up a bit, so they made contact while in the neutral position, and finally, everything worked. What a headache!

What's left? The dash turn signals don't light when the signals are on, and the right half of the dash doesn't illuminate when the headlights are on (the left side does). All the bulbs are new and are LED, but I've heard that if the LED lights are rotated 180 degrees in the socket, they don't light (?). Not sure if that is true or not, but when I can get under there, that will be one of the first things I try. Any suggestions on what else to check, I'm open to it.

Thanks again!
