If the door lock actuators (integrated into the door latch assembly) are noisy and/or not working, the latch should be replaced. For some model years, the actuator for the sliding door is available separately from the latch.Google+

My electric door locks constantly click up and down on there own , sometimes it was every second for the whole drive. We cleaned all the contacts , but no luck. I still haven't solved the problem because ive been trying to research all of the possible things it could be. It sucks when you spend the time and money and you still have the same problem. Any help would be great!
present for multiple years. lock replaced. works better but still quite noisy.

latch on back hatch wont work again, had the motor replaced @90.000 now broke again I think due to the rust in that area on the outside
