I am having a real serious problem with my car (85' 300Zx turbo). At first, it was just the front left high beam not getting power. Now, the tail lights are out, the dashlights are out, the parking lights are out, the front right low beam is out, the front left fog light is out, the reverse lights are out, and the front left high beam is still out. We checked all of the bulbs and know that they all are good. We also checked the fuses and relays, and they are all good too. I'm clueless... any ideas?
