Question type: Maintenance & Repair

My problem is the rear passenger door, I have used vice grips to lock it, only for
it to unlock about 2 months later. I cannot lock it with power or manually. I guess
the power eventually unlocks it as when I turn off ign. the doors unlock when
ign. is turned on all doors lock eccept for the rear passenger door. can you
help?

I would say that the door lock actuator needs to be replaced. When the actuator goes bad, the door either do not lock or unlocks by itself, just like in your car.
