Dome light and door lock issues

[Dwight]

I have a 2002 AWD Asrto van. Recently when I take a left turn my dome light will come on until I straighten out my turn. I have checked all the doors and they are shut. I cleaned the contacts on the sliding door. Yesterday my door locks kept clicking on, numerous times, while I was driving and I was not hitting the door lock button. Any ideas as to the cause of these electrical issues?
Thanks

Check the door wires near the hinge.

I had the same problem. The light switch on the sliding door jamb has a plastic end. The plastic end was broken off leaving the long enough to engage when the van was stationary with the door closed but...when driving, the door would vibrate just enough to let the switch turn on and off again and again. This activates the interior lights and will unlock and relock the doors. It is a $2.97 fix, so I would try it first if I were you. Good luck.
