I've been searching around the forum most of today trying to find something similar to the situation I have on my '78 280Z. All of the parking lights work and the lo-beam headlights work. When I turn on the hazard lights, only the driver side front and rear light blink plus the left arrow on the tach - the passenger side lights are dark as is the right arrow on the tach. Neither the left or right turn signal function. All of this used to work not that long ago. Any thoughts on why hi-beams are out and why the hazard and turn signals are malfunctioning?

I just yanked the center console out and checked the Hazard Switch and it seems in good working order. I replaced the turn signal flasher not that long ago but I think the hazard flasher is the original factory model (love where they put that one - SOOOO easy to get to ). I've taken apart the cover to the steering column but haven't really touched any of the inner workings yet.

Thanks!

Sounds like a bad ground connection somewhere.

The circuits for the left and right side are isolated in the switch. IIRC the 12VDC+ splits at the switch. Look in that area. Also, look at the wiring diagram carefully. I think there is a link to a colorized version of the wiring diagram in Blue's tech tips (link below).

With the high beams, the first thing to do is to check continuity through the high/low beam switch. If it is not working properly, consider contacting Dave Irwin (aka Zs-Ondabrain) about cleaning/repair.
