I have seen this on many Volvos and Saabs. Do you have access to a multimeter to do some electrical tests (or at test light will do)? First lets check the easiest things first. The driver side light works I'm assuming this is the low beam light. Does the high beams light work? If so, does both lights work on high beam? Double check the fuse labeled c2 (10 amp fuse) on the passenger side fuse block. Start here and get back to me so we can do some electrical measurements if needed. TY
F.Y.I.
There is a technical service bulletin (T.S.B.) Published by Volvo on updated wiring cable for both left front and right front head light assemblies designed to increase the life of both head light bulbs (and reducing the risk of melting also). This repair operation should be done to both sides by installing new wiring cable (with built in resistance to step down the energy supplied to the low beam headlights).
