Power locks not working properly

Welcome to 2CarPros.

The first thing I would recommend checking is the wiring to the driver's door main switch. Make sure nothing is loose, damaged, or corroded.

Here are the directions for removing the switch. I will add the directions for removal in order. All attached pictures correlate with these directions.

Let me know if this helps. I have to be honest, since none of the locks are working properly, I have a feeling the switch is the problem, so take your time and make sure none of the wiring is disconnected or broken. Often times, the wiring between the door and the door frame will break from bending so many times. So, check that too.
