Door lock makes an awful scream and it does not open sometimes. When I use my car remote to open or lock the doors or when the automatic door lock, the driver side door makes a scream. This problem is causing a short circuit that killed my battery. Not sure how to fix this problem, anybody has an idea?

This is a known problem to Chrysler/dodge cars.

The power door lock mech will strip gears eventually and make a loud grinding noise when trying to lock. Imagine revving an impact drill inside a car, THAT's what it sounds and feels like.

My right-rear door developed this problem earlier this year and now it had totally died. Door cannot be open.

Actually, this is a good thing, my car doesn't make as much murderous noises now. (see my other post about the break screams)
