I've read the many posts about this issue. Fuses are all good, relay is fine, even though it clicks when e-brake is let down. Long story short, I've read where people say a corroded wire is under the battery tray. I had my car all apart basically, but can not figure out a way to get to the wires directly underneath the battery tray. How is it possible to get these visible so I can check if there's a knick or something in one of the wires? The battery tray is obviously welded to the car. So how can I accomplish this, so I can possibly get my headlights to work properly? Thanks
