2015 Town & Country rear driver running light not working

So only the running lights on the rear driver side stopped
working. All functions work except for the running lights on
just that light. Braking, reverse, hazards, and turn signal all
work perfectly fine on that light. I swapped the working
passenger side rear tail light with the left driver side tail
light, and all functions work except for the running light, so I
know the taillight assembly itself and bulbs are good. Also
to note, the left taillight has trailer hitch lighting wired into it
if that makes any difference. I don't have a trailer to see if
the driver side light works for a trailer. Thank you for your
help.
