Passenger door does not lock when you push the button?

Hello,

This sounds like you have a faulty door lock actuator on that passenger side door.
The actuator is what controls the locking and unlocking function when the button gets pressed. It is an electrical component and can go bad overtime.
Another possibility is to have bad wiring to the actuator, which can prevent the actuator getting the power to operate or getting signal to function.

In order to access the actuator, the door panel needs to be removed.

Here is a helpful guide:

I have attached the wiring schematics below for your reference.

Please let me know if you have any questions.
Thank you.
