I'll keep it brief. So I have an '82 280ZX and I have the drivers side light dim while the passenger side fine. I've done all the normal fixes such as changing the headlights, cleaning the harness and connectors around the area, cleaning the connectors for the headlight, new fuses for both lights, and checking the fuse-able links but nothing changes. Interestingly enough, if you cycle the headlights on and off, 90% of the time nothing changes but every once in awhile both headlights will shine as they should (AKA no dimming). So I'm assuming the combo switch for the headlights is all messed up. But since it at least works SOME of the time, I'm thinking I might be able to do a repair rather than a replace. Any ideas on what might be causing this? A ground in the combo switch?
