Dash lights stay on after starting
 

I have a 2010 Chrylser Town & Country Touring with 125,780 miles, yesterday after i started up the vehicle all of the intsturment warning lights and bells stayed on, windshildwipers came on by it's self, no power to the doors or windows, no turn signals or A/C but still drivable, after I arrived home and turned the ignition off the dash lights remained on, I had to pop open the hood and disconnect the battery cable to make sure the vehicle was off, this happened during the wintertime, intermitted at first but no problems after that, I'm leaning towards a short somewhere in the wiring where the power cables run from the door to the dash (then again it could be something else) wondered if anybody had the same problem and a solution before having to make a trip to the dealer.:confused:
Thanks
