Head light problem

For my 1991 735i my right head light low beam does not work and i tryed getting a fresh new bulb and nothing worked and all the fuses are all good. would it be a wire problem? or anything else that can be wrong?
new at this whole BMW owner thing so any help would be AWESOME!
thank you,
donny

Go to http://www.e38.org and look at the E32 wring diagram for your car, I do not know if your lights are like the E30 but if they have the dual element bulbs(one relay for low and one for high/low), if so it may be the relay for the side you are missing. Do you have low beams with high beam selected (both high and low beams on) if so it is probably that relay.
