Relays will either be in the fusebox under the dash or under the hood. Being that you truck is an 86, there may not be a relay controlling the headlights. It may just the switch that supplies the power, so check that as well.

You may have ground-switched headlights since it's a Nissan. If you do have a relay, I want to say it's under the hood. I don't think the relay would be your problem though, because you're likely to have both lights come on, or neither (I don't think they have dedicated left/right relays). I'd start checking the wiring at the bulbs. How does the harness look, pretty ratty?

There is a bad contact point in the wiring switch. As I have read your post several times as it is not very clear.

Start by replacing the switch as Auex has indicated as a beginner.

From there, you will want to inspect all the wiring, and any ground points that directly relate to the light assemblies.

Either of the three, will give you intermittent failures.

Yeah, all good possibilities, and it's been my experience that it's your ground.
