I'm assuming you started with the easiest first. Fuses, then checking if the actual harnesses are plugged into the individual items that are not working.
Have you checked the harness that runs from the roof down to the floor harness? I would check that first. FSM will show you location where the harness is located. Do you know if there are working bulbs in the dome light and map lights? Could be as simple as changing out the bulbs or making sure both are plugged in.
Have you check the headlight switch on the dash to make sure it is plugged in?
Also check the motors to make sure they are also plugged in.
This write up should give you an idea on how to check the headlight motors.
