Passenger low beam on 05 CS does not come on. All other lights work fine. I've tried unclipping the wiring harness and plugging it directly to the back of the housing....no luck. I've swapped the light bulbs & ballasts between the driver's side and passenger side. Driver's side will work with passenger side bulb & ballast, but passenger side will not work with either. Any idea whay else I can check? Is there a fuse specific to the passenger low beam and nothing else?

TIA
