I was sitting in my friends driveway waiting for him to get home and all of a sudden my dome light comes on. I didn't think twice and turned it off.
But later that night and since when I use the car the dome light randomly comes on and the window randomly goes up and down a little like when you close and open open the door. Any ideas?

 

Door switch is faulty tricking the car into believing the door is being opened...most likely. Doubt it would be very hard or costly to replace

 

Thanks
