Front door locks not working?

There are several components that can cause this.
First off, does the passenger side door lock switch work make the front door locks work? If so, then the issue is more related to the driver door switch or wiring for the driver side door lock switch.
If it doesn't work also then the issue is more with the power door lock actuators itself.
Second, there is a possibility that there is a wiring issue preventing the door lock actuators to work. If the power door lock switch unlocks and locks the rear two doors also then it wouldn't be the switch itself.
If you need a wiring diagram or remove and replace instructions for the door lock actuators let us know what you are looking for.

Here are the wiring diagrams for the driver and passenger door lock actuator. I highlighted all the circuits to the door lock actuators.
