Hi,
Are all of the locks making a noise but not working? Since you hear a noise, it doesn't sound like a power issue. It could be a ground problem as well. If only one door is doing it, then the actuator itself could be bad.
Regardless, I attached the entire wiring schematic for the door locks. This is for a vehicle without a smart key. If you have one, let me know. Also, if it is a hybrid, let me know.
I cut the pics in half to make them readable. I did overlap them so you can follow from one to the next.
Here is a link you may find helpful as well:
