Re: Troubleshooting: High Beams Not Working.
One shot is correct that they switch the grounds but they use that to trigger ther relay and the relay sends power to the headlights, like I said this is so difficult not being with the car. Now in your first post you said you have no power at the lights on hi beam or flash to pass mode and you replaced the relay. Dude my light bulb just turned on: Which relay did you replace? If you replaced the headlight relay you might want to look for the dim relay and replace that. It's in the small relay block(R/B No.4) right behind the fuse/relay panel under your hood. Look at page 21 of the wiring file NW FJC sent you.
