Saturn Ion Blinker

My 2004 Saturn Ion 2, with 306K miles has a blinker/running light, which is the same bulb, issue I can not figure out. With the car in park and the headlights off the running light is out (it should be on), with the car in drive it works, with the headlights on, in either drive or park, the running light works, the blinker doesn’t work in either position and as I said before its the same bulb. No issues with the passenger side blinker/running light. Tried a new bulb but that didn’t work. Tried the bulb from the passenger side and that didn’t work. Inspections due this month and I would like to correct issue before it goes for inspection.
