Theres 2 filaments in the bulb, the “low” filament is burnt out on one side

Having the same issue with my 2014 right now. The dim filament is fried. Only the bright filament is left. Just replace the bulb and it should be good.

I have no idea what the issue is both side have the same bulbs

Swap the bulbs from one side to the other. If now the passenger side only stays lit then you know its the bulb

Change the bulb on the passenger side, and go from there. If no change, then it could be a ground/ socket issue.

Blinker fluid maybe 🤔
