Headlights won't turn on!
So I probbed the green wire on the dimmer and there is power
So follow it out. From the dimmer, two wires go out through the bulkhead connector, out into the engine bay, around to the front of the car in the lighting harness, and go to the headlights connectors. THE GROUND for both lamps is normally "Y"ed together to one ground. If that one ground goes bad neither will work.
Pull one lamp, I'd pull driver's side. Drop the lamp out, let it hang on the wire. Probe the rear of the connector for power. Regardless of which beam is activated, only one terminal should be "hot" (power.) If TWO have power, you have a ground problem.
Follow the harness visually. AT some point, the ground terminal should be bolted to the rad support.
