Okay so I have no Taillights, and my right head light doesn't work in my 88 300zx. All turning signals and brake lights work but not the right head light or taillights. I checked the fuses and relays and they appear to be fine. I was gonna try taking the steering wheel off and cleaning the light switch but that's all I could think of.

 

When I put my AE dash back together, I did not reconnect the turn signal switch tightly..and I got all sorts of funky light issues. Had a heart attack until I checked it..plugged it in tight and viola!

I hope you nail it..in my experience that plug is key to lights functioning properly.
Perhaps follow the cable to the opposite end as well and make sure all connectors are clean.

 

There are complete electrical diagrams in your factory service manual (XenonZ31 Reference) and they can be traced on large 11x17 print outs using colored markers. Yeah, takes time.

Assuming all your fuses are good, the issue is usually dirty or corroded harness connections, especially anywhere under the hood. Inside the dash, too, if you live anywhere near salt water. The trick is to trace each step in the harness from the light control stick on the steering column to the headlights/other lights that aren't working right. Separate the connectors, test with a multimeter, key at 'on' position, spray corrosion cleaner/brush connectors, dry, retest and reconnect. For the lazy headlight, I would start there at the front and work back to the control.

Wish there was a short cut! But you may get lucky and find it fast.

 

Okay ill try this, thank you.

 

Ill look in to this too if the other thing doesnt work. Thanks for the help
