I'd check all your light sockets for corrosion, sometimes the contacts get corroded down and you might be having power backfeeding into one circuit from another. I'd bet that your passenger's front turn signal/running light is the culprit. Reason being, when the hazards are operated, the lights all operate on part of adifferent circuit than when you use the turn signals. So when you're using your right turn signal, power is feeding back into the lights and is getting into the drivers side turn signals. If checking bulbs and sockets don't work then other things to check out and possibly replace would be the combination flasher relay and the hazard switch.
