2005 Chrysler Town and Country dash lights ---sliding doors

Turned on ignition switch, no dash lights -no turn signals - no brake lights except light on lift gate-
radio-heater controls illuminated and working normal--
cruise control normal--hi and low beam work but no
illumination on dash -- BEFORE-- this problem neither
sliding door would operate using inside passenger
switch-- but -- doors operated normal using remote
or overhead panel switch--child safety switch in open
position.
At the same time as the 'no dash light problem' at
35 to 45mph [approx] the car feels like it is trying
to go into gear, you feel a back and forth or in and
out feeling, slight but my passenger felt it. This
is not felt at highway speed or with cruise on.
