Dodge 2005 Door Sensors

Hi: Own a 2005 Carvan. Yesterday, the door warning light; the odometer; and the doom light came on and would not shut off. It’s as if the car thinks one of the doors are ajar-they are not. We turned the doom light off but the battery went dead overnight-reading lights either came on or I didn’t notice them. Is this a sensor problem that I can fix or try to fix. If not, what sort of problem is it and how much to repair. The day before this happened, my drivers side window was left open and rain came in on the door panel-if this has any bearing.

Thanks

Roger
