The turn signal switch is reletive to brake lamps, not park lamps.
If the brake/turn element of the rear bulbs work your problem is not in yellow or green wires. Back to the browns. Good luck
Exactly. I had brake light trouble on a Charger I had and I wound up taking the steering wheel off , take turn signal switch out, cleaned the contact points with sand paper and it fixed it. If the tag light is not working then there is something up with the headlight switch.
