Driver's side low-beam is not working. When I check voltage at the bulb harness I only get 5.5V, compared to 13 at the same point on the pax side. I checked voltage across the harness and grounding directly to the battery, same result, so I don't think I'm dealing with a ground problem in the wiring. I also checked the voltage at the harness that connects the headlamp assembly to the vehicle wiring and again got 5.5V so somewhere the voltage feeding this side is being reduced. The affected wire is blue on white, ground is green on black. I have looked for wiring diagrams but cannot find any that show the wiring I need.
Seriously considering just bringing a + wire across from the pax side harness. Running aftermarket HID so the operating amperage is very low compared to the load of the original halogen bulbs.
