So here is the situation.

The domelight unit does not work at all. None of the buttons or switches work and either does the front dome light when I open and close the car. I can not open my sunroof or anything, its as if the whole domelight unit is busted. I even pulled it down and took a look using a electricity checker thing I noticed that once I give the unit, or wires, some ground all of a sudden the front dome light lights up. Also, my rear dome light does turn on when I open the doors but since the rear domelight button is on the front domelight unit itself I cant turn it off and on manually. The vanity lights on both driver and passenger dont work and the rear view mirror doesnt change color at night, and it looks like these are all connected to the front dome light unit. I checked every single fuse in my car three times over. I dont know what to do. The dome light unit itself will run close to 300-400 dollars from junkyard I found. Anyone know what the problem is?

Regards,
Daniel
