Is the front passenger door on your Infiniti FX (or QX70) not locking or unlocking with the remote or interior switch?

This brand new door lock actuator assembly is likely the fix.

It's specifically for the front right (passenger side) door on 2009 to 2017 Infiniti FX35, FX37, FX50, and QX70 models.

It's an unbranded part but comes with a 1-year warranty.

Made from a mix of plastic and stainless steel, it's built to be durable and promises easy installation.

It's a direct replacement – you take the old one out of the door panel and put this one in.

The part is black and comes in its original packaging.

It's made in China.

If your door only works manually with the inside handle, or you hear a clicking sound but no action, the actuator motor inside this unit has probably failed.

Swapping it out will restore full power lock/unlock function to that door.
