Ok, when i bought the car the harness on both sides have been cut and just wires sitting there, so i put connectors on there and ran HID's. The other day my passenger side one stopped working and since i thought it was just the HID i took it out and put a regular bulb in and nothing happened. I plugged them both up to the other side and they both work fine on the drivers side. I'm guessing it's a wire but i have no idea, if someone could point me in the right direction on what to check and how to fix that would help A LOT.
