I just realized that only my driver side door is locking and unlocking both with the key fob and the power door switches. When I hit the lock/unlock button on the door switch it sounds like it is trying to do something on both the driver and passenger side so I am thinking probably actuator.

My question is will the front passenger side door lock actuator keep the rear doors from locking and unlocking as well? Or do I possibly have 3 bad door lock actuators? Thanks
