Yes, I believe so.

It turns out these headlamp circuits are individually fused, Bob. Since they share the same initial feed (and one side works), the problem is with the second circuit, probably starting at the fuse.

Fuse 6 is the left low beam circuit, Fuse 7 is the right. Here's a pic of the Power Distribution Center (PDC), the underhood fuse block...

Check out your #7 fuse and let me know if we need to keep looking.

Thanks,

No, it's a feed from the low beam relay, also in the PDC. Did you check to see if power is present on both sides of the fuse once turned on, Bob? The PDC may have an internal splice problem that isn't transferring power to the circuit. I've seen some of these PDCs get pretty corroded inside...

I'll check some more stuff while you're doing that.

You might need to roll the PDC over and check connector C3 (violet wire) for power with the low beams on. That's not handy, especially since you pretty much have to take the battery out to do that. This might require some jumper cables to connect the battery to the van for power testing.

Here's the lighting circuit for headlamps...

Note the common feed from the relay and the internal PDC power splice. They emerge as violet/ red and violet colored wires but from two completely different connectors at the PDC base. I haven't been able to find a good diagram of the connectors, doesn't look like I'll be able to.

From the PDC, it appears there are no more intermediate connectors all the way to the right side headlamp, so it would have to be a broken wire between the two points or the PDC isn't feeding the circuit. It's hard to say where to start, but a quick inspection of the front wiring would be good. I'm not sure at this point just where the loom is routed to get to the right front corner of the van; maybe you'll be able to tell.

Your target wire color is violet (no tracer). See if you can locate it in the loom at a midpoint and test it there for power. Either way, you'll know which way to keep looking at that time.

I'll keep looking for a good C3 connector pinout and description (my diagrams rename the connectors, making the wiring diagram info worthless). You'd be looking for the same violet wire from one of those connectors as well.

Back in a bit!

G301 is the ground source number, but since your high beams work, it has to be good. They share the same circuit.

A jumper would work for a short while... you bet. That's probably the best choice right now with the amount of daylight we have left (and the amount of disassembly that might be required).

Use a 16 ga. wire or bigger and fuse it if at all possible. Had you found power at either of the Fuse 7 terminals? That would be an ideal source to take it from.
