The power door lock on my car can be opened or closed on the driver's door, but I cannot open three passenger doors. However, I can close all four doors. The switch on the passenger front door makes some noise but it won't open the door lock.
I replaced the master switch, but it did not solve the problem. Any suggestion will be appreciated.

There are a number of things that could cause this, so we need to start with checking the voltage at the actuators that are not working.

There is a chance that we have actuator issues or something like a possible ground issue.

Depending on the voltage at each actuator (start with the passenger front) we will know what next steps to take.

I am attaching the wiring diagrams below, so we need to take these and access the actuator and lock the door and see if you have 12 volts going to the actuator.

Please let me know what questions you have, and we can go from there.

Thanks

It sounds to me like your door lock actuators have failed. Can you post a video of you locking and unlocking the locks with the switch and remote if you have one? That would help us guide you to the next step.
