Hey guys,
I have the same problem with my auto door locks.
I replaced the assembley on the passenger side (which fixed it so far), now it is doing it everyonce on the driver side.
(bought some new plastic gears on ebay first, then found some mabuchi motors to replace inside the assembley, but they arrived after i had bought the new door latch).
When I had the door latch assembley built out and still connected to the wiring, i had a feeling that the motor blocks in one direction under load, the mechanism 'flips back'then and triggers the opening process.
Not sure if this is how it works,...
Do you have any new infos by now?
according to the door chime, which sounds once you have the key in the ignition and you open the door:
If you cut the thinnest wire in the ignition key assembley (i think it is black and red), the annoyance stops.
Theoretically, it could have an effect on the door lock situation as well, I had this wire cut after i already had the door problems and nothing changed on this side after it.
Any thoughts?
