Recently my passenger side headlight stopped working, so I replaced the bulb, but it still didn't work. The bulb works, I tested it. So then I tried switching the actual headlights. I took the driver side headlight & plugged it into the passenger side, it worked. I took the passenger side headlight & plugged it in the driver side, it didn't work. I also bought new fuses and replaced both headlight fuses, still no luck. Any ideas?
