Door lock switch plug isn't working

clentl

My driver side door lock plug is not working. I can unlock the driver and passenger side doors from the passenger side switch, so I know it isn't the door actuator. I have also put the passenger side switch that does work on the driver side plug and it still doesn't work. I also have two other lock switches, since I replaced my door handle assemblies, that I have tried on both the passenger and driver sides. They all work on the passenger side, but none work on the driver side. I do not know what to check next, it appears the problem is the plug forward into the harness I guess.
