2007 Ford Explorer

I have a 07 Ford Explorer XLT 4x4. I am having some issues with my dash,
The instruments work but a lot of the time the lights on the dash do not work,
the radio lights do not work. The E-Brake light is always on the door ajar light
is always on and a Real (TPMS) light is on. when the problem is occurring
the turn signals work on the outside but not on the dash, and the 4x4 select
will not work.While Driving all the warning lights on the dash will go off and
the dash will start working and so will the 4x4 select this may last 20 minutes
may last an hour or maybe even just a few moments then the dash lights go
off the warning lights come back on and the 4x4 select will not work again.
Vehicle drives great otherwise just a pain in the rear. any ideas???
