This is a NEW power door lock actuator.  this part work on this vehicle: 2009 to 2017 Infiniti FX35 FX37 FX50 QX70 passenger rear door - right rear door. ( does not comes with cables - you must switch the cables from the old actuator) ( I will include a video link to show you how to switch the cables - it is very easy to do it and only takes a couple of minutes ) contact me if you need it for any other doors. This part comes with lifetime warranty even if you sell the car. In order to qualify for the lifetime warranty you need to send us the old unit (the part you are removing from your car) using a pre-paid return shipping label that I will include. It is easy, just put the old part in a box, put the prepaid label on it and drop it in any post office. International buyers will not receive the prepaid label. need more than one actuator?  2 actuators = combine shipping for one shipping amount 3 or more actuators = FREE SHIPPING Have any questions? contact me.
