Nope, no low beams at all now, passenger or driver. Another new issue is the highbeam dash idiot light isn't working. Isn't that circuit 36 off of 37 driver highbeam - which works?:.

I checked the dash headlight switch for continuity across the circuits, it seems fine. I jumped the headlight switch socket in the various circuit configurations, and it made no difference in the lowbeams not working. I assume the problem isn't the headlight switch. 

The passenger-side outer/inner headlights and turnsignals are grounded to the chassis behind the outer headlight. Since I have turnsignals and highbeams all around (both outer and inner since I have a SA setup), is there another ground I don't know about? The driver side low beam being intermittent is a new problem. 

New problems are what happens when playing with 33 y/o wiring. 

The list wisdom would be greatly appreciated.
