I searched for anyone else having this issue, but was unable to find anything similar that worked.

Car is an 88 Formula, but has a 87 front wiring harness as I "believe" the original harness had the same issue.

I have LED switchbacks in the front bumper lights that run white with the driving lights and amber with the turns.
The problem is that both the turn signals for the passenger side are not working (I switched the bulbs from the other side and the same doesn't work, so its not the bulbs)

Once again, I "believe" the original harness had the same issue, but I could be wrong, I switched the harnesses over the summer when I tore the car down to the frame.
I think the idea was to fix this same problem, but at this time I don't remember.
I just got power back to the car the other day so I am rediscovering the issue.

I thought about trying to put a new socket on the front turn signal to see if that fixes the problem, but I don't know if that explains why the side signal isn't working either.
The fender grounds are in place on both sides, horn works, etc.

Any ideas other that me trying to solder on a new turn signal socket?

Check the bulbs in the side marker lights and the turn indicators in the instrument cluster. Is the issue thar the lights don't illuminate, or that they don't blink?

All the bulbs work, both in the instrument cluster and the exterior markers themselves.
The issue seems to be the the exterior lights are not getting the power/signal to flash

Check the grounds on the bulb sockets. Fairly common issue.

sockets themselves are free of corrosion, PO used plenty of electrical grease.

I second the grounds. I had one side that wouldn't flash, the ground wire at the front of the bumper turn signal was broken, but appeared just fine until I really yanked on it. Long story. But, as for the flasher units. Did you replace both flashers? And if so, did you use a flasher intended for LED's?

Replace w/ normal bulb to check the socket etc.

Leave socket out to see the filaments.
Park = dim filament only
Turn = bright filament only

Both filaments on for each function is ground problem.
Ground problems often cause Sneak Path ground w/ normal bulbs too.
