Have you swapped the headlamps to see what that might do?
What do the connectors look like for the left side vs. the other for corrosion?
How rusty is this car?

I cleaned one ground near the battery, though it didn't need it. There's no rust of any kind. The engine comparment is as clean as new. Little to no corrosion in the several connections I inspected. I did swap headlight bulbs, same problem (so its not the bulb). Voltage to the left bulb is also 6-7 volts. So I'm thinking it IS a relay thing and the voltage is being backwashed through the right headlight cuz when I uplug the right headlight bulb, the left side goes out. But where are these relays?
Our Superscrew Dealership "never heard of such a thing" (not according to my buddy who works on 'em). Didn't know whether one or two relays. "Bring it in". Sure hate to. I'll have to take out a second mortgage.

well, taking off the lower two large pieces of plastic under the steering wheel will allow for access to the relays I'm aware of.
there are some 4 to 8 relays up under there ALL of them are on the left side of the steering wheel shaft, they also all seem to be the round steel design with the diagram printed on the metal.
There are 2-4 that are "C clipped" onto the top side of the ECU (engine control computer with 3 bolts attaching it to the steering frame.) Remove those three bolts and getting to these relays will be less hassle.
The other 4 or 6 relays are up above the fuse block - and I do mean UP, they too are held in with those same designed "C clips" for snap out and pull down of the relay and the wiring to see them easily out in the open air dangling for ease of swapping the relays.
Here's a time testing trick of the relays as they are all the same design.
At least one of these relays is for the A/C system so if you have the A/C on while unpluging the relays one at a time you'll find out which one(or more) they are and can then then stick those relays into the *STILL EMPTY A/C socket for proving those relays work and that way your not climbout back up and looking to "SEE if the lights are on or not".
care to try that?

Got any ideas on a good repair manual. Most I've looked at have unreadable pictures or improper location of parts/accessories or absent of troubleshooting/diagnostics.

The best manual is the factory service manual set. They can be pricey, but they some times pop up on ebay or from members on the board.. I paid $30 plush shipping for mine

I'll try tinkering some more and let you know. Meantime I can only drive during the daylight....
