The above pic will be the wiring diagram that we will start with first. You need to gain access to the headlamp switch connector.
The should be 12 volts on the red and light green wire at the headlamp switch connector. If okay then turn the headlamps on and see if 12 volts comes out on the light green wire. This circuit then leads to the highbeam switch mounted on the column. You will need to gain access to the connector for this as well. Once you have access to this then make sure all the wiring is firmly seated in the connector.
Check these items and then let me know what you find.

So the circuit leading up to the high beam switch checks good at this point. If there was a short anywhere the fuse would be blown. There is no speration of driver or passenger side lights at the highbeam switch in the wiring diagram so Im not sure why you think the passenger side lights are shorted to ground. The circuit goes into the highbeam switch on the light green wire. When on low beam, 12 volts comes out on the violet and white wire when the headlamp switch is on and the high beam 12 volts comes out on the red and orange wire when the high beams are turned on. Make sure you check both of these using the multimeter. I know you said you jumped the light green and read and orange but please check the low and high beam like I stated using the multimeter so that I can see where we need to go next. The reason I ask you to check it exactly the way I describe is so that I can keep the same path in my mind for checking it.
Will do as you request.
Just to clarify, I jumped the LG to R/O across the connector block to see if the high beam would light, but nothing. I checked the resistance of the R/O to ground at the connector block without a bulb and the R/O is connected to ground. I checked the bulb connector on the passenger side and the B, R/O and V/W are all connected to ground.
I have owned the vehicle since new and have not made any modifications to the wiring. My daughter has been driving this vehicle and has told me that the headlights would die periodically while driving then come back on.
Just one other fact. Flashers work as do parking lights and turn indicators. Fog lights work, but do not go out on high beam. High beam light does not illuminate.
The circuit from the high beam switch goes from there to the headlamps.
So please check the low beam and high beam circuits at the highbeam switch with it plugged in. I need to know the voltage readings so that I can point you in the next direction. Because if voltage is present but still not at the bulbs themselves, I will have to have you check other connectors inbetween. Thats why I need to know the voltage readings.
If 12 volts is going in on the light green wire as you say and not comign out on the red and orange or the violet and white then we have an issue with the switch. Here is a picture of the high beam switch connector so that we can be sure your checking the correct circuits.
Terminals 18, 19, and 20 are the ones we need to be worring about.
So is the low beams now working now that the #19 is fully seated? I assume the 0V or 13.78 on V/W is from moving the switch to high beam and back?
Good, I have a feeling they will now start working
