make sure the contacts are clean and plugged in properly
Each type of vehicle has a unique design to its headlight assembly. Some have the headlight and emergencey lights in one housing others have them seperated.
behind the headlight
I would start with replacing the head light switch

Yes.
bad headlight switch
A 1990 300zx headlight is recessed into the bumper. To remove it, first loosen the headlight bracket bolts. Unplug the lights and push the housing outward. Be careful not to ruin the weather stripping for the lights.
It's the head lights only.
The headlights work on a totally different relay than the parking and fog lights. The headlight relay or headlight fuse is usually blown when only the parking and fog lights work.
On a four headlight system there are two filaments for the inner lights. They have a filament for a high beam and one for a low beam.
Headlights,interior lights stop working.checked all fuses. I would suspect the headlight switch and/or the electrical connection at the headlight switch is faulty.
REPLACE THE PASS SIDE HEADLIGHT
