Headlights and tail lights dont work?

I have a 97 Toyota camery LE V6 So my headlights will only work if i hold the high beams on for a few seconds then let go. My tail lights didnt work. Then they came on for a bit. Now they are not working again Also most things on the dash dont light up. Ex. My high bean icon, seat belt icon, brake lights etc... show more I have a 97 Toyota camery LE V6

My tail lights didnt work. Then they came on for a bit. Now they are not working again

Also most things on the dash dont light up. Ex. My high bean icon, seat belt icon, brake lights etc come on. But the gas tank gadge and speed thermometer dont light up.

Power windows do work but not the power locks

We have replaced the relay and ive replaced the switch. Neither fixed the problem as of yet.
We have checked all the fuses and made sure the fuses were getting power.

Now i have checked the wiring myself, i am no mechanic but nothing looked bad.

Hope this is enough info and thanks in advance!
