Answer
Check for a bad, or broken ground wire for the left side of the car.  It sounds like you still have power, but just not a complete pathway to ground.  It doesn't even have to be a broken wire, it could just be a corroded connector.  Pull the lights out again, and examine their elctrical connections, are any discolored from high heat?...ie., too much resistance.  Use a test light to try and narrow down the region where the ground is no longer available for this lighting circuit.  Happy hunting!
