What are all the ways to get a headlight working? on 1990 BMW 735i

The right headlight and fog light do not work. I have tried replacing the bulbs, checked the wiring, and replaced the switch on the interior dash. None of these seemed to work.

did you check the lighting control module???
no I haven't. I will check that. Thanks.

Napa carries the headlight pigtail and connectors for BMW, So it must be a common part that fails But there are 4 different styles So best to drive to your local Napa store So the counter person can match it directly and you can find a store near you here
