No crank no start no dash

I have a 2005 T&C that no longer starts. The last
time it ran, the instrument cluster went crazy ( all
lights/dials went on/off, full/empty, top/bottom
several times) then worked fine. Went to start it a
few minutes after shutting down and it acts like
there's no battery. Instrument cluster does not
come on with the key on, turning key to start gives
no results. Tried to jump start it with no change.
Interior lights work. Radio works. Checked all fuses
and relays. All wires secure and connected.
