Hi
I have a Toyota Corolla 2000. The problem is that the tail lights don´t work, the lights in the dashboard also don't work and the medium lights in the front also don't work. I have checked the fuses but everything seems to be right. Can anyone help me please?

check your grounds

Hi,
Where should I check? I don't know much about electrical of a car, specially for this one. Even to locate the fuses box, I had to spend a couple of hours. More detailed explanation would be very appreciated.
Thanks
