Yet another light issue..left parking light not lighting but blinks with turn signal

[jeepbiscuits]

So yeah what subject says. Left parking light not lighting but blinks with turn signal. Side marker works as expected. On with headlights then blinking alternately with the parking light when the turn signal is on. So bulb works. Any idea what could be wrong?

sorry I suck horribly bad at electricity

You have a burnt out bulb most likely. There is a separate filament for the turn and running lights I believe.
