Alarm/ door lock/ interior light problem
 

One day I was driving on the highway then the cluster screen came on saying my driver door is opened. Then kept going on and off saying it was open and closed. So yesterday I just took off the door panel and could not find anything wrong with it. Since it was too cold I had to drive to work without the panel on then all of a sudden the alarm light started flashing then the car shut down and I felt a big jolt. And then turned back on and it drove fine but I drove it slow to work. Any ideas anyone I need help bad????
