Just realized the other day my passenger door lock wasnt working, truck and driver door work fine, but passenger just seems to not have "enough power" anyone have this before? What kind of system is in these things? I know on my audi when this happened all the doors and trunk went and had to replace the central locking pump, but since its just passenger I'm thinking something came loose or wore down? Any help appreciated it, its embarrasing to have the girly wait outside the car while I reach over to unlock, lol!!!
TIA

 

You can perhaps try this:

Most probably your Actuator. Common with our cars.

 

you need a new actuator
