'02 Caravan power door lock actuator problem
I have a 2002 Caravan Sport (short wheelbase version) with the 3.3L V6. Recently the driver's side power door lock began making a very loud (as in, could wake the dead) groaning/grinding noise when I used the key fob or inside switch to unlock it electrically, though no noise when locking. After about a week of this, it has now started making the noise when I lock electrically as well. Also the actuator doesn't always fully unlock or lock the door now, though everything still works fine if you operate the lock button manually or use the key in the lock.
I assumed there was probably some kind of stripped gear inside the power lock actuator, but I took mine out of the door and then took it apart and didn't see anything obvious wrong.
Two questions: (1.) Are these actuators rebuildable? If yes, where would I get parts for it, and what is it likely to need? If no, (2.) Are they available anywhere from the aftermarket, or is the dealership the only option? I checked with Advance Auto and they only listed one part number for a Dorman-branded universal actuator which I'm guessing won't work since the assembly I removed pretty obviously requires different parts for left and right.
I'm attaching a couple photos of my actuator/latch assembly if that is helpful.
