2002 BMW 330XI, high beams do not come on fully when switched to on. Momentary on then off. But they do come on when you flash to pass. low beams and fog lights work good. Any help would be cool! Thanks
check fuse and relay, if its good, than you have faulty switch, only work on low but not high beam, to turn high beam on the switch move forward which is fauty or no contact, flashing high beam move toward you which has a good contact and working. it two switch in one unit.
