Q: Side lights and tail lights - 1997 Volvo S90

The passenger side parking light doesn’t work but the directional light does. Do they run off the same bulb? The tail lights don’t work. I tried new bulbs and figured out after trial and error that’s it’s an electrical issue because I tested all the bulbs and they work. All of the relays and fuses are fine. My L main relay for my headlights in the 2nd fuse box under the hood had the prongs gone in it, so a relay wouldn’t there. But my headlights work well. Can you help me fix these problems?
