My cousins car randomly lost all lights, radio, horn and turn signals. The only way the lights will work is if you pull the dimmer and hold it back. Oddly enough though, prior to this issue the sunroof would not work, but now it is the only working accessory. I am thinking ground issue, but I have no clue where the under dash grounds are and I cannot find an diagram. Any ideas?

Hey Arron,

Start by checking all the system fuses, it could be the ignition switch itself since they had problems with them, here is a wiring diagram for the headlights though so you can get started.

Let me know what you find
