Passenger side marker turn signal on key off?

Hello,

One day last week, returning home from work, all was fine went outside around 9:00pm and saw only my passenger turn signal was on key was not in. Attempted pulling all corresponding fuses/relays. Flicked the right turn signal on and it flashed rapidly, and passenger side mirror arrow stayed solid on. It did nothing, the only thing that turned it off was unplugging the battery. Plugging in to start get where I'm going and unplug. Don't want to drain battery and get stuck. I've spent hours and hours in the cold troubleshooting and diagnosing the best I know how. Any help would be greatly appreciated. Thanks

PS:
Pulled out headlight assembly and inspected for corrosion and rubbed wired-all good.
