2000 JGC Laredo power panel on door quit working the windows, mirrors and locks.

last week all of a sudden my o/h info center said the hatch back was open, got out of
truck open and reshut it and the message went away. 2 days later started my jeep at
night to go to the store and all the interior lights were on and would not go off unless i
turned the switch on the blinker to the off position. Which is ok but now all the dash
lights are very dim at night and cant turn them up because then all the interior lights
stay on as well. Then coming home from the store the info center said my driver door
was open. It was not open. Now I have very dim dash lights. cant roll the windows all
the way up, cant adjust the mirrors and today the service engine soon light came on. I
love my jeep but man all the little issues popping up all the time are drive me crazy
and emptying my pocket book. Please help. What can be the problem?
