I had the same problem. It was a defective lamp socket on the driver's left side, Volvo Part Number 8662985. Costs me $11.24 to replace the lamp socket, which included the bulb. If you've already replaced the bulbs yourself, you will find replacing the socket pretty easy, just use a thin flathead screwdriver to delicately pry off the metal retainer clip which holds the lamp socket in place, as you'll need to reinstall the existing metal retainer clip once you've replaced the lamp socket. Two minute job.
