both headlamps work as expected in low beams but just one in high beams. switched the bulbs to rule that out and both bulbs are fine. didn't really check on the fuses because i am assuming fuses should work, or not work, for both lamps. are there any known problems with the headlamps, as i have seen other with similar problems? thank you.

UPDATE: now what used to be the only properly-working headlight only works on high beams, so either i have the driver's headlight working in high beams or the passenger's in low beams, but not both, arrrg
