Power door lock issues

[Napu(StrongWave)]

Im having a problem with the power door locks whenever opening(unlock) or Locking the doors. They all seem to lock except for the driver side rear door lock will get stuck 1 out of 4 times The locks when unlocking or locking the locks by way of door switch or key fob seem to be making a "loud typewriter" type noise..Sometimes driver front door lock is weak. Can anybody shed some light on this subject??

More than likely a sluggish actuator or a binding part.
Try cleaning the door latch by thoroughly flushing with
WD-40 or similar, followed by white lithium spray lubricant.
If that works, it's probably a good idea to lube them all.
If not, the only way of diagnosing is by removing the panel. GL

Actuator. Drivers door more-so as it is functioning more often. Not horrible to replace. I used and old style one but had to tap in an old style wiring plug into the harness for it because, of course, Ford changed it when they went to a different supplier. Now I can replace it with either/or!! Smart, eh?
