Interior lights and cruise control not working

All my interior lights do not come on when I open
the door or when I turn the light know all the way to
the right. It does brighten up the dash. Also the
cruise control doesn't work either and light doesn't
come on the dash when pressing the cruise control
and trying to set it. Is the lcm responsible for this?
All fuses are fine. Could it  be great wiring? Is a
civilian crown Victoria  base model that was use as
transportation for disable people to get around and
it had a GPS that is located on the truck with a
power supply box inside the truck. Could they have
forgot to connect something back together when
they sold the car because I notice small holes on
the the trim of the dash as if they had a monitor or
laptop attached on it just below the radio like police
cars. Could you help me.
