on my 1991 e34 my passenger side headlights just went out. no bulb cracks and no crusty wires. the high beams dont function either. the left side works fine. my LKM is ok and fuses are good. any suggestions if theres a relay for this particular issue???

They get there power through the Front Power Distribution Box, check fuses 11 and 13. should be 7.5 amp ones. If the fuse is good, pull the connector on the bulb and see if you are getting power to the connector. If you have power, you more than likely have a ground issue. Trace the wires to the ground and see if it is loose or disconnected.

Go here and get your copy of a 1991 E34 Electrical Troubleshooting Manual (http://e38.org/e34/e34_91_etm.pdf) Look at page 270-272 of the 408 pages.
