When turn signals are activated and lights are on, the only ones that work are the side lights and the rear lights both flash. Wtf. I have replaced all turn signals and rear tail/brake lights, have replaced one headlight as well with led light. When lights are off all turn signals activate. Just purchased a led turn signal flasher as well which fixed the non leds and now i have this

Check grounds. Especially behind both headlights and the one on the driver's side kick panel.
Battery terminals and the firewall ground would be great to clean too.

Like @macleanflood said above check your grounds. You did not go from incandescent bulbs to LEDs in the turn signals did you?

Replaced the whole thing which plugs into the existing incandescent
im not the best wiring person, but where should the grounds be going behind the headlights? Do you happen to have pics?
Thanks so much. I found some of the other Same issues on the forums and it appears there are some issues with the led turn signals and the way they ground or don't ground. Took them all out and all works again. I guess I will just return them and get some replacement oem.
I had this problem when I switched to all LED's. Bought three so called LED flasher units. Finally took the stock unit apart and scratched across the rapid blink circuit to kill it. That cured the problem. Maybe worth a try.
OK I am back. I have since removed all the LED Turn signals and back to stock. I have also remvoed the LED headlights.
All is working properly except one turn signal. The rear turn signal is fine unless the headlights are on. If I turn the headlights off, then it works great.
Update:
I do have LED taillight combos.

ok Someone did say that, and I still havent done it. I will do that when I get home.
I also updated that I do have LED taillights.
I’ve got led taillights with the updated flasher. They cause no problems and work perfect. Like @macleanflood said. Check them grounds!
Let me ask you this. Where did you hook the ground that came inside the taillight?
If I remember correctly it’s under one of the screws that holds the taillight on.
