Even when I'm in the car and we are driving and I try to lock all doors with from the driver side, my passenger side door does not lock. I'm trying to figure out what the actual problem is and how to resolve it without spending tons of dollars at the dealership.
Many thanks in advance!

It could be that the lock actuator is bad or the wiring to it is damaged, or the mechanical cable between the lock lever and the actuator is bound. The first thing to do would be to take off the door panel on that side and get a look at the wiring and the cable. If that all look OK, you would then want to unplug the connector from the actuator and measure the voltage on the connector while power locking the doors. If you see the pulse on that connector then you will know for sure that the actuator is bad. The actuator is part of the door lock/latch assembly, so you would need to replace that entire assembly.
